CSV to JSON and JSON to CSV Converter

Turn a CSV table into JSON, or a JSON list into CSV. Quoted cells, doubled quotes and line breaks inside a cell are read the right way (RFC 4180). Your data is converted in your browser and is not uploaded.

Handy before you load a file in Print Label / PDF, or to tidy a list with the list cleaner.

Good to know

With "JSON types" on, 7 becomes a number, but a value with leading zeros such as 007 stays text, so codes are not damaged.
Up to 20,000 rows and 2 million characters are handled at once.
The protection option adds an apostrophe in front of risky cells, so a spreadsheet does not run them as a formula.
