Frequently asked questions
Will commas in my data break the CSV?+
No — values containing commas, quotes or newlines are wrapped in double quotes per the CSV standard, so the file imports cleanly everywhere.
Does it change my data?+
Only the delimiter and necessary quoting change; the cell contents themselves are preserved exactly.
Is it free to use?+
Yes — it is completely free with no sign-up, no account and no usage limits. There is no watermark and no paywall, so you can process as many files as you like.
