- The checker skips volatile formulas, links to other files, and cells without a saved Excel result.
Field notes
The flow distinguishes a local compatibility check from the hosted service: the former is described as staying in the browser, while API use requires a separate workbook upload. The FAQ says the hosted service stores the workbook for calculations but not scenario inputs or outputs. It also identifies skipped cases, including volatile formulas and links to other files, so the advertised Excel compatibility has stated boundaries.
