When using Number Format, the most common questions are about display results, text values, and date recognition; this section covers 3 frequent questions.
FAQ
Why did the cell not change after I applied a number format?
- Check whether the cell content is stored as plain text.
- If the value starts with an apostrophe, remove the text-style input first and try again.
- Select the cell again and apply a Number, Currency, or Date format.
Why is my date displayed as a number?
- Select the date cell with the unexpected display.
- Open Tools → Home → Number Format.
- Choose the Date category and apply it to see whether the date display returns.
Does Number Format change the actual value in a cell?
- Number Format mainly changes how the value is displayed.
- Check the formula bar or later calculation results again; in normal cases, the underlying value is not directly rewritten by a display-format change.
- Before applying changes in bulk, test the display result on a small sample first.
