CSV to JSON
A local CSV to JSON converter for exports, tables and test data: paste CSV or upload a small file, choose header handling and get JSON.
How it works
The tool parses CSV locally in your browser: detects the delimiter, respects quoted values and converts rows into objects when header row mode is enabled. With headers disabled, the result is an array of arrays.
When to use it
CSV to JSON helps with quick API payloads, checking table exports, preparing test data, prototyping ETL and manually normalizing small exports.
How to use it
- 1Paste CSV into the editor or upload a small .csv file.
- 2Keep delimiter detection on or choose comma, semicolon, tab or pipe manually.
- 3Enable header row mode if the first row contains field names.
- 4Click Convert, then copy or download the JSON.
