Frequently asked questions
- How do I convert CSV to JSON?
- Paste CSV with a header row, choose your delimiter, and the JSON array appears immediately. Copy or download as .json.
- Does the CSV need a header row?
- Yes — the first non-empty line becomes the keys of every JSON object.
- How are quoted fields handled?
- We follow RFC 4180: double-quoted fields can contain commas, newlines and `""` for literal quotes. Most spreadsheet exports work out of the box.
- Are values typed as numbers?
- No — every cell is exported as a string so leading zeros, dates and IDs survive intact. Convert types in your code if needed.
- Which delimiters are supported?
- Comma (default), semicolon and tab. Pick the one that matches your file.
- Is my CSV sent to a server?
- No. Parsing and conversion run entirely in your browser.
- Can I convert European-format CSV?
- Yes — switch the delimiter to semicolon. We also accept both LF and CRLF line endings.
- What about empty cells?
- Empty cells become empty strings. Drop or transform them in your downstream code as needed.
- Can I convert big CSV files?
- Yes — the practical limit is your device's memory. Tens of MB convert in under a second.
- Is this CSV to JSON free?
- Yes — free, no signup, no limits.
