Use Paste Special to Multiply by -1
This method allows you to bulk convert positive numbers to negative numbers in place without needing extra columns or formulas.
By utilizing the Paste Special feature, Excel can perform mathematical operations directly on the selected cells based on the copied value.
Type '-1' into any empty cell on your worksheet and press Enter.
Select the cell containing '-1' and press Ctrl+C, or right-click and choose Copy.
Highlight the entire column or specific range of positive debit values you wish to convert.
Right-click the highlighted range and select 'Paste Special' from the context menu.
In the Paste Special dialog box, select 'Multiply' under the Operation section and click OK. You can now delete the temporary cell containing '-1'.
Apply Custom Number Formatting for Red Parentheses
After converting the numbers to negative, apply custom formatting to display them in red parentheses for clear financial reporting.

Frequently Asked Questions
Can I convert negative numbers back to positive using this method?
Yes. You can use the exact same Paste Special method to multiply the negative numbers by -1 again, which will convert them back into positive values.
Is there a formula to convert positive numbers to negative without overwriting the original cells?
Yes. If you prefer to keep your original data intact, create a new column and enter the formula =-A1 (assuming A1 is your target cell). Drag the fill handle down to apply the formula to the rest of the column.
Why did my numbers change into date formats after using Paste Special?
This happens if the standard Paste operation overrides the cell format. To avoid this, select 'Values' under the Paste section and 'Multiply' under the Operation section in the Paste Special dialog box.
How do I make the negative numbers appear in red without parentheses?
To display negative numbers in red without the parentheses, open the Format Cells dialog, select Custom, and use the format code #,##0;[Red]-#,##0 instead.
