A minus sign alone easy to miss?
In a dense table full of numbers, a lone minus sign is easy to overlook, and a deficit or loss can slip right by. Displaying negative numbers in red makes problem entries jump out immediately, without needing a closer look.
Also worth learning: aligning currency symbols with Accounting format
Accounting format is a natural companion to this β it not only handles negative values distinctly but also lines up currency symbols and decimal points neatly across a whole column.
Frequently Asked Questions
Can I also show them in parentheses?
Yes. The Negative numbers list includes an option that combines red text with parentheses, giving you a format like "(1,000)" that's common in accounting documents.
Could conditional formatting achieve something similar?
Yes, a conditional formatting rule like "less than 0" can produce a similar effect, but the negative-number option in Format Cells is simpler and more direct for this specific purpose.
