CSV ↔ JSON
Convert CSV or TSV to JSON objects or arrays.
About CSV ↔ JSON
Convert tabular text into JSON or export a JSON table as delimited text. Header mode creates objects with field names; headerless mode uses arrays of arrays.
Steps, example, and limitations
How to use it
- Choose the conversion direction, delimiter, and header mode.
- Paste or import the data and run the conversion.
- Review the output and the CSV export options before saving.
Example
Input
name,code Alex,0012
Result
[{"name":"Alex","code":"0012"}]Things to know
- CSV values remain strings, which preserves leading zeros. Header names must be unique and rows must have consistent widths.
- Spreadsheet-safe export intentionally prefixes formula-like cells. Quote large JSON identifiers when numeric parsing would lose precision.
