What to expect
Excel input supports XLSX. Formula cells use their saved values; the tool does not recalculate formulas. Exports contain values, not the original formatting. CSV and JSON imports preserve text where possible.
Local processing
Your files and inputs are processed in your browser and are not uploaded. Download or copy results before leaving. Normal site and library requests still reach the hosting service.
