Frequently Asked Questions
- Which Excel formats are supported?
- Both .xlsx (Excel 2007+) and .xls (legacy Excel) formats are supported, plus .csv files.
- Can I convert multi-sheet Excel files?
- Yes. Select which sheet to convert, or convert all sheets and download as a ZIP with separate files for CSV/TSV, or a single combined JSON object.
- What output formats are available?
- CSV (comma-separated), JSON, TSV (tab-separated), and Excel (.xlsx). Each has configurable options like delimiter, encoding, and header row control.
- Is there a file size limit?
- No hard limit — processing runs in your browser, so very large files (100 MB+) may be slow depending on your device.
- Does it work on mobile?
- Yes, works on all modern browsers including mobile Safari and Chrome on iOS and Android.
