Frequently Asked Questions

How are CSV headers handled?

The first line of your CSV is automatically extracted as the object keys for each subsequent row in the JSON array.

Does it support commas inside quotation marks?

Yes! The parser properly supports quoted values containing commas and escaped double quotes according to standard RFC 4180.

Can I convert large datasets?

Yes! Since the parser operates in pure JavaScript directly in your browser, spreadsheets with thousands of rows parse in milliseconds.
