When using BYCOL, users commonly ask about 3 issue types: formula errors, unexpected results, and filling the formula across multiple cells; this section answers 3 common questions.

FAQ

What should I do if BYCOL returns a #VALUE! error?

  1. Check whether the parameter data types are correct and make sure numeric parameters do not include text or extra spaces.
  2. If needed, clean the source data first and then enter BYCOL again.
  3. Make sure you use English commas as parameter separators, then press Enter again to confirm the formula.

Why does the BYCOL result not match what I expected?

  1. Check whether the reference range is correct and make sure no cells were missed or selected by mistake.
  2. Check whether the related cells are formatted as numbers instead of text.
  3. Use the formula checking tools on the Formula tab to review the calculation step by step.

How can I use BYCOL in multiple cells at once?

  1. Enter and confirm the BYCOL formula in the first target cell.
  2. Move the pointer to the fill handle at the lower-right corner of the cell and drag across the target range, or use copy and paste to extend the formula.
  3. Check whether relative and absolute references behave as expected, and use $ to lock references when needed.
