Worked example
People CSV with a header
Input: name,age Ana,31 Ben,28 Output: [ { "name": "Ana", "age": "31" }, { "name": "Ben", "age": "28" } ]
- Every value stays a string, exactly as written in the CSV. The converter never guesses that 31 should become a number.
- The delimiter (comma, semicolon, tab and others) is detected automatically by the parser.
- Quoted fields containing commas, quotes or newlines are handled following the standard CSV quoting rules.
CSV has no number type, so all cells are text. Keeping them as strings avoids silent changes such as losing leading zeros in codes.
About this tool
The CSV to JSON Converter reads pasted or uploaded CSV and produces a JSON array. With the header option on, each row becomes an object keyed by the header names, which is the shape most APIs and scripts expect.
