FAQ

What should I do if ISERROR shows an error after I enter it?

1. Check whether the formula begins with =.
2. Check whether the parentheses are paired correctly and whether parameters are separated correctly.
3. Review the function hint and confirm that you entered a valid value, expression, or reference.
4. Press Enter again and confirm whether the result returns to normal.

How can I check the parameter format for ISERROR?

1. Select any cell and type =ISERROR(.
2. Review the syntax hint shown in the formula input area.
3. Complete the parameter based on the hint and finish the formula.
4. If needed, continue nesting IF or other functions.

Why does the ISERROR result not match what I expected?

1. Check whether the tested content actually returns an error value.
2. Confirm whether the referenced cell contains text-formatted numbers or invalid references.
3. Check whether there is a circular reference or an upstream formula issue.
4. If needed, press F9 to recalculate and review the result again.

What is the benefit of using ISERROR together with IF?

1. Use ISERROR first to test whether an expression returns an error.
2. Then use IF to return different content for TRUE or FALSE.
3. When an error appears, you can show a prompt, a blank value, or a replacement result.
4. This makes spreadsheet results easier to read and easier to process later.
