Frequently Asked Questions

Does the first row need to be a header?+
Yes — the first row is treated as column headers and becomes the key names for every JSON object produced from the remaining rows.
Does it handle commas inside quoted fields?+
Yes, fields wrapped in double quotes can safely contain commas and the parser will not split them incorrectly.
Is my CSV data uploaded anywhere?+
No — the conversion happens entirely in your browser using JavaScript. Your data never leaves your device.
