Questions

How do I convert XLSX files?
Choose your XLSX files or drop them on this page, pick the format you need (CSV, JSON, TSV and ODS), then select Convert and save the results.
Is it safe to convert XLSX files here?
Yes. Decant converts XLSX files in your browser, so they aren't uploaded to a server, and nothing is stored or logged.
Can I convert many XLSX files at once?
Yes. Add as many as you like and they convert together; when there are several results you can save them all as one ZIP.
