CSV to JSON Converter
Convert CSV data to JSON online with header mapping and smart type detection, no upload needed
CSV to JSON Tips
- With the header option on, the first row becomes object keys and every other row becomes an object.
- Type detection turns 42 into a number, true/false into booleans, and empty cells into null - turn it off to keep everything as strings.
- Quoted fields may contain commas, quotes (doubled), and even line breaks - all handled per RFC 4180.
- Auto-detect counts commas, semicolons, and tabs in the first line and picks the most common one.

CSV looks simple until values contain commas, quotes, or line breaks - then naive split-by-comma parsers silently corrupt your data. This converter implements a real RFC 4180 state machine: it tracks quote state character by character, maps the header row to object keys, and optionally coerces numbers, booleans, and null so the output is ready for APIs, MongoDB imports, and JavaScript.

الأسئلة الشائعة
إجابات على الأسئلة الشائعة حول تنسيق Csv To Json
Yes, completely free with no registration. All parsing happens locally in your browser.
Yes, as long as the field is quoted per RFC 4180. The parser correctly handles embedded commas, doubled quotes (""), and multi-line quoted fields - things that break naive split() approaches.
Yes. Turn off the "First row is the header" option and every row - including the first - is emitted as a plain array of strings.
Values that parse as finite numbers become JSON numbers, the exact strings true and false become booleans, and empty cells become null. Any other value stays a string. Disable the option to keep every value as a string.
Yes. Leave the delimiter on auto-detect (it counts candidate delimiters in the first line) or select semicolon or tab manually.
