FAQ
What should I do if GAMMALN returns an error?
- Check whether the argument is in a valid numeric format.
- Make sure the formula uses the correct separators instead of localized punctuation that the formula parser does not accept.

Why does the GAMMALN result look different from what I expected?
- Check whether the referenced cell or value is correct.
- Confirm that the input cells are not stored as text.
- Test the formula in a blank cell first so you can verify each argument step by step.
How can I use GAMMALN in multiple cells at once?

=GAMMALN(...)formula in the first target cell. - Move the pointer to the fill handle at the lower-right corner of the cell.
- Drag down or across to copy the formula to additional cells.
