Question details

The user wants to automatically change the background color of specific cells from red to white when data is entered into another related cell in a different column.

How to Automatically Change Excel Cell Colors When Data Is Entered

Product: Excel
Device & OS: not provided
Scenario: Tracking data entry where a cell needs to visually indicate that input is missing in an adjacent column.
Observed behavior: Cells require dynamic formatting so they remain highlighted in red until the required data is entered, at which point they should automatically clear the formatting and become white.

Before you start

Ensure your spreadsheet contains the necessary headers and data layout before applying conditional formatting rules to avoid overriding existing formats. Determine exactly which column will act as the trigger and which column will change colors.

Solution 1Recommended

Use Conditional Formatting with a Custom Formula

Apply a custom formula within the conditional formatting menu to evaluate whether an adjacent cell is blank and change the target cell's fill color accordingly.

To achieve the effect where a cell remains one color until data is entered elsewhere, you can set a default fill color for your target cells and then use conditional formatting to override that color when the condition (data entry) is met.

Apply Default Cell Color

Select the cells in your target column (e.g., B2:B100). Go to the 'Home' tab and use the 'Fill Color' bucket tool to manually paint these cells red. This serves as the default 'waiting' state.

Select the Target Range

With the target cells (e.g., B2:B100) still selected, navigate to the 'Home' tab on the ribbon.

Open Conditional Formatting

Click on 'Conditional Formatting' in the Styles group, then select 'New Rule' from the dropdown menu.

Enter the Formula

Choose 'Use a formula to determine which cells to format'. In the formula box, type =A2<>"" (assuming column A is your trigger column and row 2 is the first row of your selection). This formula checks if cell A2 is not blank.

Set the White Fill Format

Click the 'Format' button, navigate to the 'Fill' tab, and select the color white (or 'No Color'). Click 'OK' to close the Format Cells dialog, then 'OK' again to apply the rule.

Use Conditional Formatting with a Custom Formula

Dynamic Formatting Applied: Once applied, entering any data in column A will instantly change the corresponding row's cell in column B from red to white.

Powerful Spreadsheet Tool

Use WPS Spreadsheet for Advanced Conditional Formatting

Easily set up complex conditional formatting rules, including custom formulas to change cell colors dynamically based on adjacent data entry, using WPS Spreadsheet.

1. Open WPS Spreadsheet: Launch WPS Office, open your workbook, and manually fill your target column with a red background.
2. Select Target Cells: Highlight the cells you wish to format dynamically.
3. Apply Rule: Go to Home > Conditional Formatting > New Rule, choose the formula option, and enter your logical formula (e.g., =A2<>"").
4. Format to White: Click Format, choose a white fill, and apply. The cells will now automatically change color when data is entered.

Frequently Asked Questions

Can I apply conditional formatting to an entire row based on one cell?

Yes. Select the entire row range, go to Conditional Formatting, and use an absolute column reference in your formula, such as =$A2<>"". The dollar sign ensures that every cell in the row looks specifically at column A.

Why isn't my conditional formatting formula working correctly?

Ensure that the row number in your formula exactly matches the first row of your selected range. If you select B2:B10, your formula must start with A2, not A1. Mismatched rows will cause the colors to shift out of alignment.

Can I highlight cells if they contain a specific text instead of just any data?

Yes. Instead of checking for non-blank data (<>""), you can use a formula like =A2="Completed" to change the color only when that specific word is entered into the adjacent cell.
