Frequently Asked Questions

Does it support different delimiters?
Yes. Choose comma (,), semicolon (;), or tab as the delimiter. Tab-separated files (TSV) are also supported.
What happens to numeric values?
Numbers are automatically converted from strings to numbers in the JSON output. Strings remain as strings.
Can I convert without a header row?
Yes. Uncheck 'First row is header' and columns will be named field1, field2, field3, etc.
Is my CSV data sent to a server?
No. Parsing happens locally in your browser with JavaScript.
