Is your Excel workbook showing #REF!, #VALUE!, #N/A, or formulas that return incorrect results?


Mendstack helps you fix broken Excel formulas without paying for a complete spreadsheet rebuild.


What's included for $20:

  • Diagnose and correct existing formula issues in one Excel workbook.
  • Test the affected calculations against your expected results.
  • Return the corrected Excel file.
  • Provide a short explanation of what was wrong and how it was fixed.
  • Include one revision for corrections within the agreed scope.


Common problems I can help with:

  • Broken references and formula errors
  • IF, SUMIF, COUNTIF and lookup formulas
  • VLOOKUP, XLOOKUP and INDEX/MATCH issues
  • Incorrect calculations and formula logic


Not included: Password recovery, external data connections, full workbook audits, or building new spreadsheets from scratch.


Please provide your workbook, identify the affected cells, and explain what results you expect.
