Frequently asked questions
Is CSV to JSON conversion free?
Yes, completely free with no sign-up, no watermark, and no limit on how often you use it.
Is my data uploaded anywhere?
No. Every conversion runs in your browser, on your own device. Your file is never sent to a server or stored anywhere but your device.
Does this handle commas inside a quoted field?
Yes -- a field like "Smith, Jr." wrapped in quotes is parsed as one value, not split on that comma.
Does this work on mobile?
Yes -- it works in any modern browser on a phone, tablet, or desktop, with no app to install.
