I will fix your broken excel or google sheets formula and explain it

#N/A, #REF!, #VALUE!, a SUMIF that returns 0, a lookup that only finds the first row. Send me the file and tell me which cell is wrong.

What you get:

• Your file back with the formula fixed, compatible with your Excel version or with Google Sheets.
• A short note: what was wrong and how the new formula works, so you can change it later yourself.

I check the result against your data before delivery, not just that the error went away. If the sheet needs to be rebuilt rather than patched, I tell you before starting.

If the file has sensitive data, a copy with sample data works just as well.

I work in writing through Fiverr messages. No calls needed.
