Making negative numbers red in Excel is a simple and effective way to quickly identify and differentiate them from positive numbers. This visual cue can be particularly useful when you’re dealing with financial data or any dataset where negative values are significant.
Step by Step Tutorial: Making Negative Numbers Red in Excel
Before we jump into the steps, let’s understand what we’re aiming to do. We’re going to apply a custom format to the cells containing numbers. This format will automatically change the color of negative numbers to red, making them stand out.
Step 1: Select the cells with numbers
Click and drag your mouse over the cells that contain the numbers you want to format.
When selecting cells, make sure you only select the ones with numbers. If you select cells with text or dates, this formatting might not apply correctly.
Step 2: Open the Format Cells dialog
Right-click on one of the selected cells and choose ‘Format Cells’ from the context menu.
Alternatively, you can press Ctrl + 1 on your keyboard to open the Format Cells dialog box directly.
Step 3: Navigate to the ‘Number’ tab
In the Format Cells dialog, click on the ‘Number’ tab to access the number formatting options.
This tab contains various formatting options including currency, accounting, date, and more. We’re interested in the ‘Custom’ category at the bottom of the list.
Step 4: Select ‘Custom’ format
Scroll down in the Category list and select ‘Custom’.
The Custom format option allows you to create your own number format by using specific codes that Excel recognizes.
Step 5: Enter the custom format code
In the ‘Type’ field, enter the following code: 0.00;[Red]-0.00
This code tells Excel to display positive numbers with two decimal places and negative numbers in red with two decimal places and a minus sign.
Step 6: Click ‘OK’
After entering the custom format code, click ‘OK’ to apply the formatting to the selected cells.
Once you click ‘OK’, the selected cells will now show negative numbers in red. If you’ve made a mistake in the custom code, you can always go back and edit it by following the same steps.
After completing these steps, you’ll see that all the negative numbers in the selected range are now displayed in red. This change will automatically apply to any new negative numbers you add to the range.
Tips: Making Negative Numbers Red in Excel
- Use the ‘Accounting’ number format if you want negative numbers to be displayed in red with parentheses instead of a minus sign.
- If you want to remove the red color from negative numbers, simply change the number format back to ‘General’ or another appropriate format.
- Remember that changing the color of a number does not change its value; it’s purely a visual aid.
- You can apply this formatting to entire rows or columns if you expect them to contain negative numbers.
- Experiment with different custom codes to find the format that works best for your data and your needs.
Frequently Asked Questions
What is the custom format code to make negative numbers red?
The basic custom format code to make negative numbers red is 0;[Red]-0. However, you can modify it to include decimal places, currency symbols, or other elements as needed.
Positive numbers will display normally, while negative numbers will appear in red. This visual distinction can help prevent data entry errors and make it easier to interpret your data.
Can I use this formatting for currency values?
Yes, you can format currency values to appear in red when they are negative. Use the custom format code $0.00;[Red]-$0.00 for dollars, for example.
This format will display positive currency values as normal and negative values in red with a dollar sign and two decimal places.
Will this formatting change if I move the data to another worksheet?
The red formatting for negative numbers will remain if you cut and paste the cells into another worksheet. However, if you copy the values only, the formatting will not carry over.
To maintain the formatting, make sure to paste the cells with their original format or apply the same custom format to the new range of cells.
Can I apply this formatting to existing data?
Yes, you can apply this custom formatting to cells that already contain data. The formatting will update automatically to reflect the changes.

How do I apply this formatting to an entire column or row?
To format an entire column or row, click on the column letter or row number to select it, then follow the same steps to apply the custom number format.
