When your total comes out as zero
If numbers are clearly entered but AutoSum keeps returning 0, there is a good chance those values are stored as text rather than real numbers. Converting them to numbers fixes the problem immediately.
Splitting data into columns is worth knowing too
This issue often shows up right after importing or splitting data β pairing this fix with Text to Columns covers most of the common headaches that come with messy imported spreadsheets.
Frequently Asked Questions
What if the warning icon never appears?
Some data will not show the icon at all β in that case, the multiply-by-1 method or a formula-based approach is a more reliable fix.
The numbers still are not calculating correctly after converting β what now?
The cell format may still be set to "Text." Try changing the format to "Number" or "General" and converting again.
