Frequently Asked Questions
- Is this CSV to JSON converter free?
- Yes, 100% free. No account, no limits, and nothing is uploaded — parsing runs entirely in your browser using the papaparse library.
- What delimiters are supported?
- Comma (,), Tab (TSV files), Semicolon (;), and Pipe (|). Select the correct delimiter in the options bar for accurate parsing.
- How does the header row option work?
- When 'First row is header' is enabled, the first row of your CSV becomes the property keys in the JSON objects. When disabled, each row is output as an array of values.
- Can it handle quoted fields and commas inside fields?
- Yes. The converter uses papaparse, which correctly handles RFC 4180 CSV — including quoted fields, commas inside quotes, and escaped quotes.
- Does it work on mobile?
- Yes, it works on all modern browsers including mobile Safari and Chrome on iOS and Android.
