## Excel conditional formatting for blank cells

Everything you need to know about conditional format for empty cells in Excel

As simple as it may sound, highlighting blank cells with conditional formatting is quite a tricky thing. Basically, it’s because a human understanding of empty cells does not always correspond to that of Excel. As a result, blank cells may get formatted when they shouldn’t and vice versa. This tutorial will take a close look at various scenarios, share some useful bits on what is happening behind the scenes and show how to make conditional format for blanks work exactly the way you want.

### Why does conditional formatting highlight blank cells?

Summary: conditional formatting highlights blank cells because it makes no difference between blanks and zeros. More details follow below.

In the internal Excel system, a blank cell equals a zero value. So, when you create a conditional format for cells less than a certain number, say 20, blank cells get highlighted too (as 0 is less than 20, for empty cells the condition is TRUE).

Another example is highlighting dates less than today. In terms of Excel, any date is an integer greater than zero, meaning an empty cell is always less than today’s day, so the condition is satisfied for blanks again.

Solution: Make a separate rule to stop conditional formatting if cell is blank or use a formula to ignore blank cells.

### Why aren’t blank cells highlighted with conditional formatting?

There may be different reasons for blanks not being formatted such as:

• There is the first-in priority rule that stops conditional formatting for empty cells.
• Your formula is not correct.
• Your cells are not absolutely empty.

If your conditional formatting formula uses the ISBLANK function, please be aware that it identifies only truly empty cells, i. e. cells that contain absolutely nothing: no spaces, no tabs, no carriage returns, no empty strings, etc.

For example, if a cell contains a zero-length string («») returned by some other formula, that cell is not considered as blank:

Solution: If you want to highlight visually empty cells that contain zero-length strings, apply the preset conditional formatting for blanks or create a rule with one of these formulas.

### How to highlight blank cells in Excel

Excel conditional formatting has a predefined rule for blanks that makes it really easy to highlight empty cells in any data set:

1. Select the range where you wish to highlight empty cells.
2. On the Home tab, in the Styles group, click Conditional Formatting > New Rule.
3. In the New Formatting Rule dialog box that opens, select the Format only cells that contain rule type, and then choose Blanks from the Format only cells with drop down:
4. Click the Format… button.
5. In the Format Cells dialog box, switch to the Fill tab, select the desired fill color, and click OK.
6. Click OK one more time to close the previous dialog window.

All the blank cells in the selected range will get highlighted:

Tip. To highlight non-empty cells, select Format only cells that contain > No blanks.

Note. The inbuilt conditional formatting for blanks also highlights cells with zero-length strings («»). If you only want to highlight absolutely empty cells, then create a custom rule with the ISBLANK formula as shown in the next example.

### Conditional formatting for blank cells with formula

To have more flexibility when highlighting blanks, you can set up your own rule based on a formula. The details steps to create such a rule are here: How to create conditional formatting with formula. Below, we will discuss the formulas themselves

To only highlight truly empty cells that contain absolutely nothing, use the ISBLANK function.

For the below dataset, the formula is:

`=ISBLANK(B3)=TRUE`

Or simply:

`=ISBLANK(B3)`

Where B3 is the upper-left cell of the selected range.

Please keep in mind that ISBLANK will return FALSE for cells containing empty strings («»), consequently such cells won’t be highlighted. If that behavior is not want you want, then either:

Check for blank cells including zero-length strings:

`=B3=""`

Or check if the string length is equal to zero:

`=LEN(B3)=0`

Aside from conditional formatting, you can highlight blank cells in Excel using VBA.

### Stop conditional formatting if cell is blank

This example shows how to exclude blank cells from conditional formatting by setting up a special rule for blanks.

Suppose you used an inbuilt rule to highlight cells between 0 and 99.99. The problem is that empty cells get highlighted too (as you remember, in Excel conditional formatting, a blank cell equals a zero value):

To prevent empty cells from being formatted, do the following:

1. Create a new conditional formatting rule for the target cells by clicking Conditional formatting > New Rule > Format only cells that contain > Blanks.
2. Click OK without setting any format.
3. Open the Rule Manager (Conditional Formatting > Manage Rules), make sure the «Blanks» rule is at the top of the list, and tick the Stop if true check box next to it.
4. Click OK to save the changes and close the dialog box.

The result is exactly as you would expect:

Tips:

• You can also exclude blanks by creating a conditional formatting rule with a formula that checks for blank cells and selecting the Stop if true option for it.
• Also, you may be interested to watch a video showing how to apply conditional formatting if another cell is blank.

### Conditional formatting formula to ignore blank cells

In case you already use a conditional formatting formula, then you do not really need to make a separate rule for blanks. Instead, you can add one more condition to your existing formula, namely:

• Ignore absolutely empty cells that contain nothing:

NOT(ISBLANK(A1))

• Ignore visually blank cells including empty strings:

A1<>»»

Where A1 is the leftmost cell of your selected range.

In the dataset below, let’s say you wish to highlight values less than 99.99. This can be done by creating a rule with this simple formula:

`=\$B2<99.99`

To highlight values less than 99.99 ignoring empty cells, you can use the AND function with two logical tests:

`=AND(\$B2<>"", \$B2<99.99)`

`=AND(NOT(ISBLANK(\$B2)), \$B2<99.99)`

In this particular case, both formulas ignore cells with empty strings, as the second condition (<99.99) is FALSE for such cells.

### If cell is blank highlight row

To highlight an entire row if a cell in a specific column is blank, you can use any of the formulas for blank cells. However, there are a couple of tricks you need to know:

• Apply the rule to a whole dataset, not just one column in which you search for blanks.
• In the formula, lock the column coordinate by using a mixed cell reference with an absolute column and relative row.

This might sound complicated on the surface, but it’s a lot simpler when we look at an example.

In the sample dataset below, suppose you wish to highlight rows that have an empty cell in column E. To have it done, follow these steps:

1. Select your dataset (A3:E15 in this example).
2. On the Home tab, click Conditional formatting > New Rule > Use a formula to determine which cells to format.
3. In the Format values where this formula is true box, enter one of these formulas:

To highlight absolutely empty cells:

`=ISBLANK(\$E3)`

To highlight blank cells including empty strings:

`=\$E3=""`

Where \$E3 is the upper cell in the key column that you want to check for blanks. Please notice that, in both formulas, we lock the column with the \$ sign.

4. Click the Format button and choose the fill color you want.
5. Click OK twice to close both windows.

As a result, conditional formatting highlights a whole row if a cell in a specific column is empty.

### Highlight row if cell is not blank

Excel conditional formatting to highlight the row if a cell in a particular column is not blank is done in this way:

2. On the Home tab, click Conditional formatting > New Rule > Use a formula to determine which cells to format.
3. In the Format values where this formula is true box, enter one of these formulas:

To highlight non-empty cells that contain anything: value, formula, empty string, etc.

`=NOT(ISBLANK(\$E3))`

To highlight non-blanks excluding cells with empty strings:

`=\$E3<>""`

Where \$E3 is the topmost cell in the key column that is checked for non-blanks. Again, for the conditional formatting to work correctly, we lock the column with the \$ sign.

4. Click the Format button, choose your favorite fill color, and then click OK.

As a result, an entire row gets highlighted if a cell in a specified column is not empty.

### Excel conditional formatting for zeros but not blanks

By default, Excel conditional formatting does not distinguish between 0 and blank cell, which is really confusing in many situations. To resolve this predicament, there are two possible solutions:

• Create 2 rules: one for the blanks and the other for zero values.
• Create 1 rule that checks both conditions in a single formula.

#### Make separate rules for blanks and zeros

1. First, create a rule to highlight zero values. For this, click Conditional Formatting > New Rule > Format only cells that contain, and then set Cell value equal to 0 like shown on the screenshot below. Click the Format button and select the desired color.

This conditional formatting applies if a cell is blank or zero:

2. Make a rule for blanks with no format set. Then, open the Rule Manager, move the «Blanks» rule to the top of the list (if it isn’t already there), and tick the Stop if true check box next to it. For the detailed instructions, please see How to stop conditional formatting on blank cells.

As a result, your conditional formatting will include zeros but ignore blanks. As soon as the first condition is met (the cell is empty), the second condition (the cell is zero) is never tested.

#### Make a single rule to check if cell is zero, not blank

Another way to conditionally format 0’s but not blanks is to create a rule with a formula that checks both conditions:

`=AND(B3=0, B3<>"")`

`=AND(B3=0, LEN(B3)>0)`

Where B3 is the upper-left cell of the selected range.

The result is exactly the same as with the previous method — conditional formatting highlights zeros but ignores empty cells.

That’s how to use conditional format for blank cells. I thank you for reading and look forward to seeing you next week.

What tasks would you advise to solve for those who are preparing for a Python interview?

## Field properties, aliases, and table display options—ArcMap

• Navigating the list of fields on the Fields tab
• Setting field properties
• Field Aliases
• Table Display Options
• Quick Set Properties and Field Aliases
• Set Column Width

Each field, or column, in an attribute table has properties that describe its content and how its data should be displayed. You can view and, in some cases, edit the properties for each field on the Fields tab of the Layer Properties and Table Properties dialog boxes. The settings on the Fields tab are used to determine how attributes are displayed in ArcMap, including in the attribute table window, in the Identify window, and when editing in the Attributes window.

For example, you can:

• Specify which fields should be displayed in the table (visible fields).
• Set an alias for the field name so that the field appears in the table with a friendly name. Aliases are useful because you cannot change the field names in the data after it has been created.
• Set formatting for numeric fields (currency values) or set the number of decimal places to display. The formatted data is displayed in the Identify window, the Attributes window, legends, table of contents, table windows, and so on.
• Define a display field that is used in the Identify window, the Attributes window, and other functionality in ArcMap.
• Write an expression that can be used to construct a more complex row element rather than the contents of a single field.
• Set table display and column handling options.

Some field properties are set when the feature class or table is created and cannot be changed later (data type, precision, and number of characters).

### Navigating through the list of fields on the Fields tab

The settings you select on the Fields tab, including visibility, field order, and field aliases, are used in ArcMap in all places where you work with attributes—in the attribute table window, in the Identify window and when editing in the Attributes window. These settings also apply to joined fields, although they can only be edited when they are not joined, that is, in source tables.

The left side of the Fields tab contains a list of all fields in the feature class or table, including all attached fields. You can check or uncheck a box so that it may or may not be visible in ArcMap. You can toggle the visibility of all fields by clicking Enable All Fields or Disable All Fields by holding down the CTRL key and clicking the check box, or by pressing CTRL+SPACEBAR if the field is highlighted in the list.

The order in which fields are listed on the Fields tab is the default display order for fields in ArcMap. To change their order, click on a field in the list and drag it to the desired location, or use the up and down arrow buttons to move the field in the list. You can select multiple fields and change their order at the same time. By clicking on the arrows, you move all selected fields one position up or down the list. To move a field to the very top or bottom of the list, click the drop-down arrow next to the arrow buttons and use the Move To Top or Move To Bottom commands.

To sort the list alphabetically, click the Table Options button and select ascending or descending order. To return to the original data order, click the Table Options button and use the Reset Field Order command. Using the Table Options menu, you can switch between displaying aliases and field names.

### Setting field properties

When you click on a field in the list on the left, the properties of the individual fields are displayed on the right side of the tab (if you have multiple fields selected, the right side is left blank). You can change the properties shown in the Appearance section, but you cannot change the properties listed in the Field Details section. If you click on a line on the right, a line describing that property will appear at the bottom of the right pane.

Display properties specify how the contents of this field are displayed in ArcMap. The field alias is its alternative name, which may be more understandable to the user than the real one. If you want to distinguish certain fields—for example, to make them more visible when editing in the Attributes window—set the Highlight property to Yes. This will change the font color and background shadow to make the fields stand out from the rest. You can also set the field to read-only, which means it can be seen but not edited, regardless of geodatabase permissions. Also, if you are working with numeric fields, you can set the number format by clicking the ellipsis button on the Number Format row. Each category has currency, interest, etc. - its own set of available formatting options.

All items in the Field Details list are ArcGIS system properties, which include the field's data type, name, precision, length, coded value or range domain names, and whether null is allowed. These will vary depending on the data source (geodatabase, shapefile, and so on) and field type (text, long integer, date, and so on). Because these properties are visible but not editable, they are shown in gray instead of black.

### Field aliases

An alias is an alternative name that is a more descriptive description of the contents of a field. Unlike real names, aliases may not comply with database restrictions and may contain up to 255 characters - including spaces, numbers, and special characters. By setting aliases, you can name fields more descriptively than real names.

For example, you can alias "Validity Date" for a field stored in the database as "DEED_DATE".

There are two types of field aliases: feature class field aliases (geodatabases only) and layer field aliases. You work with feature class field aliases in ArcCatalog on the Feature Class Properties dialog box. When a database feature class is added to ArcMap, its field aliases are initially used for the layer's field aliases. However, there is no connection between the two types of aliases after that. Properties set in ArcMap temporarily override data source property settings, but are not carried over to the data source. This means that if you change a layer's field alias, it will not change the feature class's field alias, and if you change a field's alias in the geodatabase, it will not update the layer's field alias for any layer created from that feature class.

The only way to save what is set on the Fields tab is by saving the map document or layer to a . lyr file.

### Table display options

When you open a table, you can customize its appearance in several ways. For example, if you don't like the default table font, you can change it and set a different font size. You can make changes to all tables or just one - each table can have its own individual settings.

When examining the contents of a table, you can resize columns to better see the values ​​in the table. You can also swap columns to make it easier to compare values ​​in one column with values ​​in another. Freezing table columns can also be useful when examining the contents of a table. Pinned columns are rigidly fixed in the table on the left and are separated from other columns by a thick black line. When a table is scrolled horizontally, all other columns move as normal, while pinned columns remain fixed.

Some table display options you can set include:

• Changing the width of visible fields and rearranging them
• Pinning a field so that it is always visible when scrolling through a table
• Choosing whether or not to show a value or description for fields with subtypes and domains
• Change the color or font used to display attributes in tables
• Set the height of headers and cells
• Set the character that indicates that the field is indexed (indexes can improve query processing speed)

#### Setting the height of headers and cells

You can change the height of column headers (the top row of the attribute table with field names) and cells. By increasing the heights of headers and cells, you can increase the height of rows.

If the column or cell header height you specify has enough room for additional lines, then the field name within the column header or cell content will wrap to the next line if it does not fit the current column width. This can be especially useful when the table has fields with long names or long text fields, such as fields with descriptions or comments. Increasing the height of headers or table cells will make it easier to work with such fields.

The default height of the header is 125 percent of the font size. The default cell height of the header is 115 percent of the font size. If you set the cell height to less than 115%, it can make it difficult to edit the contents of the cells.

Generally, you should leave the default values ​​of 125% and 115% for the height of headers and cells on the Tables tab in the Setup menu > ArcMap Options dialog box so that all new tables you create use the default settings. If you want a specific table to have higher rows so that long text fields wrap to the next rows, as shown in the figure above, set the desired setting in the Table Options > Appearance dialog box. In this case, the given row height will be applied only to this particular table.

### Quickly set field properties and aliases

With the table window open, you can right-click on a field header and select Properties from the menu to open a dialog where you can set and view specific properties for that field. In this dialog box, you can set a field alias, make the field invisible or visible, change the formatting for numeric fields, and view (without changing) other field properties such as whether null values ​​are allowed in the field, the precision, and the length of the field.

### Set column widths

The table window displays fields as columns. You can drag the separators between fields to the left or right to change the width of the field, up to the point where the field can be completely hidden.

You can also auto-reset column widths to undo your changes. The Restore Default Column Widths command on the Table Options menu restores all default column widths. In addition, it opens all fields that are completely hidden by reducing their width to zero. The Restore Default Column Widths command does not reset the order of the columns, so if columns have been rearranged in the table window, their order will not change after using this command.

If a table field is completely hidden, it will be shown with a thicker separator in place of that field. Thus, it is always easy to see that one or more fields are hidden. If multiple fields are hidden in the same place, this will be shown with an even thicker separator line.

To open a hidden field, drag the separator line to the right, or double-click on the separator. To reveal all hidden fields in a table, use the Restore Default Column Widths command on the Table Options menu. Hiding fields completely in the table window can be useful because allows you to customize the desired table view, including the table view for printing using the Print command in the Table Options menu, without completely turning off the margins, which turns off the margins in all other places.
