Convert CSV to JSON or JSON to CSV — choose the delimiter, paste the data, and copy the result.
CSV and JSON are the two formats that move data between systems that do not speak the same language. A spreadsheet exports CSV, an API expects JSON, and the distance between the two is a conversion that every developer has written by hand at least once. This tool does it in both directions, with the delimiter already set for the most common cases.
The CSV parser handles quoted fields, fields that contain the delimiter, and the two most common line endings. The JSON output is an array of objects, with the first CSV row as the keys — the format most APIs and import scripts expect. Going the other way, the tool reads a JSON array of objects and writes the CSV with the keys as headers.
Your data never leaves the page. The conversion runs in JavaScript on your device, which means you can paste a dataset with personal information, API keys or production records and nothing is uploaded, logged or stored anywhere.
No. The conversion runs entirely in JavaScript on your device.
Comma, semicolon and tab. Brazilian systems often export with semicolons because the comma is the decimal separator.
Yes. Fields wrapped in double quotes are unquoted, and escaped quotes inside them are handled.
An array of objects, with the first row of the CSV as the keys. This is the format most APIs and import scripts expect.
Only your device memory. Files of several megabytes convert fine in modern browsers.
