Excel Control Guard

Excel Control Guard reviews Excel workbooks locally before signoff. Choose a current .xlsx or .xlsm workbook and optionally choose the last approved copy. The app checks for common workbook risks: macros, hidden sheets, hidden rows and columns, external links, formula errors, volatile formulas, and typed numbers inside formulas. When a last approved copy is selected, Excel Control Guard compares both files and flags formulas that changed, disappeared, or were replaced with typed values. Export a PDF signoff report with workbook findings, sheet summaries, change counts, and a workbook fingerprint. Everything runs locally. No account, no server, no workbook upload.
