CSV to JSON Converter

CSV to JSON Converter is a free tool that runs entirely in your browser, with no data ever sent to a server. Convert a CSV table to JSON, or the other way around.

What it's for

Turn a spreadsheet export into JSON a program can use, or the other way around to read JSON data back into a spreadsheet.

What this tool does not do

This tool follows the standard CSV format (RFC 4180, quotes to escape commas and line breaks). A CSV that deviates strongly from this standard may give an unexpected result.

Frequently asked questions

Are fields containing a comma handled?

Yes, as long as they're wrapped in quotes, as required by the standard CSV format: "Smith, John".

Is my data sent to a server?

No: the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.

Do I need to create an account or install anything?

No: the tool works directly in this page, with no sign-up and nothing to install.
