About CSV & JSON Converter

Moves data between the two formats these things usually arrive in. A spreadsheet export (CSV) becomes JSON that software can read, or the other way round. It spots whether your CSV uses commas, semicolons or tabs, turns nested JSON into flat columns, and shows the result as a table so you can check it before you copy or download it.

When people use it

Handing a spreadsheet export to a developer in the shape they asked for
Making sense of a JSON file you were sent
