Then, navigate to the ‘Home’ tab and find the ‘Conditional Formatting’ button in the ‘Styles’ group. Choose ‘New Rule’.
In the dialog box that appears, select ‘Format cells that contain.’ Set the condition for the cell value to ‘less than’ and enter zero.
After this, click on ‘Format,’ choose the red color for the font, and confirm by pressing ‘OK.’
With this rule in place, Excel will automatically turn any negative values within the selected range into red text!
Creating and Saving Custom Formats
Creating and saving custom formats in Excel is straightforward, even for beginners. To begin, select the cells you want to format.
Access the ‘Format Cells’ dialog by right-clicking and choosing ‘Format Cells’ or pressing ‘Ctrl + 1’.
In the dialog, switch to the ‘Number’ tab and select ‘Custom’.
Within the ‘Type’ field, enter a format code that defines the appearance for positive, negative, and zero values, like [Green]$#,##0.00;[Red]-$#,##0.00;$0.00. Once done, click ‘OK’ to apply your custom format.
Your custom format now will not only make negative numbers instantly recognizable but will also save the format within the workbook or a template.
Custom Format Approach for Negative Values
The custom format is a more permanent way to display negative numbers in red throughout an Excel workbook. By creating a custom number format, we tell Excel explicitly how we want positive, negative, zero, and text values to appear. Using a custom format code such as #,##0;[Red]-#,##0, any negative number entered in a cell will automatically turn red, improving readability and consistency within the workbook.
What’s more, this custom format can be saved with the workbook or even as part of a template, making it effortless to preserve our formatting preferences across various documents — a straightforward solution for maintaining visual standards in recurring reports or datasets.
Complex Formats with Number and Currency Options
For complex data requirements, crafting formats that handle numbers and currencies can be critical. Advanced Excel users often need to display various formats together, such as differentiating between multiple currency symbols, using accounting formats, or showing negative numbers in parentheses. Excel’s custom format feature allows for such detailed customization.
For instance, to format positive numbers with a dollar sign and negative numbers in red with parentheses, the format code would be [$$]#,##0.00;[Red]($$#,##0.00).
