Stays on your device · CSV, TEXT/CSV
Most CSV to JSON converters ask you to upload your spreadsheet to a server, which is an awkward trade when the file holds customer records or exported analytics. This one parses the file in your browser and gives you a JSON array keyed by the header row, with quoted commas, embedded newlines and escaped quotes all handled properly. If any column should not travel in plain text, you can mask or hash it in the same pass.
How to CSV to JSON Converter
- 1
Drop your .csv file onto the upload area — commas, semicolons and tabs are detected automatically.
- 2
Check the preview of the first five rows to confirm it parsed as you expect.
- 3
Leave every column on Keep Unchanged for a straight conversion, or mask the sensitive ones.
- 4
Copy the JSON, or download it as a .json file.
Why Use TextsPro
The file is read with the browser's FileReader and parsed locally, so nothing is transmitted and there is no size cap beyond your own machine. The parser follows RFC 4180 properly, which is where most quick converters fall down: fields containing commas, quotes or line breaks come through intact rather than splitting the row. The output is a plain JSON array of objects keyed by your header row, ready for an API fixture, a seed file or a quick jq pipeline. And because the anonymization rules are right there, you can convert and de-identify in one step instead of two.
