This FAQ covers 3 common question types about COMBIN: formula errors, result checking, and repeated use across multiple cells.

FAQ

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

  1. Check whether the parameter data types are correct and make sure the numeric parameters do not contain text or extra spaces.
  2. If the data was pasted from another source, clean it first with functions such as CLEAN and TRIM.
  3. Re-enter or update the formula, then press Enter again to confirm the result.

Why does the COMBIN result not match what I expect?

  1. Check whether the referenced cells and values used in the calculation are correct.
  2. Make sure the related cells are formatted as numbers instead of text.
  3. If needed, use formula evaluation tools on the Formula tab to inspect the calculation step by step.

How can I use COMBIN in multiple cells?

  1. Enter the COMBIN formula in the first target cell and confirm the result.
  2. Move the pointer to the fill handle at the lower-right corner of the cell, then drag across the target range, or copy and paste the formula into other cells.
  3. Check whether relative and absolute references are set as expected, and use $ when you need to lock a reference.
