Frequently Asked Questions

What delimiters are supported?

Comma (,), semicolon (;), and tab are auto-detected by counting occurrences in the first row.

Are quoted fields supported?

Yes. Fields wrapped in double-quotes, including those containing commas or newlines, are parsed correctly. Escaped double-quotes (\"\") are also handled.

Is my file uploaded?

No. Parsing runs entirely in your browser. Your CSV data is never sent to any server.
