WorkbookAPI checks whether your spreadsheet agrees with Excel
A browser-based checker compares Excel workbook formulas against their saved Excel results; running a checked workbook as an API, web form, or bulk-scenario service is described as early access.
- For
- Excel model owners needing programmatic access
- Worth noticing
- The checker skips volatile formulas, external-file links, and cells without saved Excel results; macros, Power Query, and pivots are not run.
Field notes
The current workflow is a browser check of an uploaded .xlsx file against its saved Excel results; a sample loan model is offered for visitors without a workbook. The page says files stay in the browser and identifies unsupported material, including macros, Power Query, pivot tables, volatile functions, and external-file links. API, web-form, and bulk-run options are described as early access, not as live features.
