FAQ

Last updated:July 8, 2026

When using COMPLEX, the most common issues fall into 3 groups: input errors, unexpected results, and filling the formula across cells.

FAQ

What should I do if COMPLEX returns #VALUE!?

  1. Check whether the parameter data types are correct and make sure numeric parameters do not contain extra spaces or text.
  2. Confirm that parameters are separated with English commas rather than Chinese commas.
  3. If the original data contains spaces, clean it with CLEAN or TRIM and then enter the formula again.

What should I do if the COMPLEX result is not what I expected?

  1. Check whether the referenced cells or ranges are correct.
  2. Confirm that the related cells contain numeric values that can participate in calculation.
  3. Review the entered parameters again and verify the calculation step by step if needed.

How can I use COMPLEX in multiple cells?

  1. Enter the COMPLEX formula in the first target cell.
  2. Select that cell, drag the fill handle at the lower-right corner across the target range, or copy and paste the formula into other cells.
  3. After filling the formula, confirm that relative and absolute references behave as expected.
