Your spreadsheet is wrong somewhere.
Find it. Fix it. Prove it.

• Numbers stored as text that silently drop out of totals
• Formulas that drifted from the pattern the rest of the row uses — the classic wrong-total bug
• SUM ranges that stop one row short and miss a value sitting right below
• Lookup keys padded with spaces that break VLOOKUP/XLOOKUP matches

Broken references, hardcoded “plug” numbers inside formula blocks, duplicate keys, totals that disagree for business reasons. You get the exact cell, the evidence, and a plain-English suggestion — the decision stays yours.

In a seeded test workbook with 13 planted defects (3 critical), SheetFix repaired 5 directly, cleared 8 findings on re-check — including the cross-foot failure that made row and column totals disagree — introduced 0 new issues, and reported the 5 judgment calls that remained. The underlying audit engine is deterministic and benchmarked on 2,700+ real-world workbooks.

Download the exact output SheetFix produced for a fictional sample workbook (Bluepine Crafts Ltd — invented company, invented numbers, with typical defects planted on purpose: a text-stored number, a space-padded lookup key, drifted formulas, a broken reference and a hardcoded plug). Findings before: 13 · auto-fixed: 5 · resolved on re-check: 8 · remaining judgment calls: 5 · new issues introduced: 0.
