Build The Excel Formula Portability Test Bench, an interactive utility that helps users identify formulas and workbook features that may behave differently across spreadsheet platforms.
Allow users to upload a workbook or paste formulas and specify the source and target environments, such as Microsoft Excel, Excel for the web, or Google Sheets.
The tool should:
Parse supported formulas and identify functions with compatibility concerns.
Flag external workbook references, platform-specific functions, macros, and unsupported features when detectable.
Create a formula dependency view for selected cells.
Generate suggested alternatives for incompatible formulas.
Explain differences in date systems, locale-specific separators, dynamic arrays, and error behavior where relevant.
Separate confirmed incompatibilities from features requiring manual verification.
Produce a migration checklist and cell-level audit report.
Allow users to test formulas against sample inputs.
Include a sample financial workbook with lookups, date calculations, conditional formulas, and dynamic arrays. Preserve original formulas and clearly mark uncertain results. Never claim full workbook compatibility from formula inspection alone. Deliver an interactive interface and an exportable audit report.
