CSV to JSON

Spreadsheets speak CSV. Applications speak JSON. Every time you export something from Excel and need to push that data into a system, the gap between the two is the first hurdle. This tool bridges it by turning CSV into JSON: the first row becomes the key names, and every row after that becomes an item in the array.

The separator is detected on its own, whether comma, semicolon or tab. Numbers and boolean values are also recognised and converted to the right type rather than left sitting as text. What you get back is already structured, ready to drop into your code or into another API.

Since none of this relies on uploads, the processing stays inside the browser itself and your data never leaves the device. You can convert spreadsheets that hold sensitive information without worrying.
