Frequently Asked Questions

What does the #NAME? error mean in a spreadsheet?

The #NAME? error appears when the spreadsheet program cannot recognize text within a formula. This usually happens if a function name is misspelled, a named range does not exist, or you entered an incomplete function without the required parentheses and arguments.

Why is Excel for the Web not showing formula suggestions?

Formula autocomplete in the web version relies on browser scripts. It may fail to appear due to conflicting browser extensions (like ad-blockers), outdated browser cache, network connectivity issues, or a temporary bug in the web application itself.

How do I fix formulas displaying as text instead of calculating?

If a formula shows up as plain text (e.g., you see =SUM(A1:A5) instead of the result), the cell format is likely set to 'Text'. Change the cell format to 'General', double-click the cell, and press Enter to force the application to recalculate it as a formula.

How do I know if I should use a comma or semicolon in my formula?

The correct separator depends on your computer's Regional Settings. Generally, regions that use a period (.) as a decimal mark use a comma (,) for formula arguments. Regions that use a comma (,) as a decimal mark use a semicolon (;) to separate formula arguments.
