About this tool

CSV to JSON uses the first row as field names and turns each following row into an object. JSON to CSV expects an array of objects and uses their keys as the header row. Parsing is done with Papa Parse in your browser.

Questions

Does it handle commas inside quotes?

Yes. Quoted fields are parsed correctly.

Does my data get uploaded?

No. Conversion runs in your browser.

What JSON shape does JSON to CSV need?

An array of objects, for example [{"name":"Ali","age":30}].

Are numbers converted?

Yes. Numeric and boolean values in CSV become numbers and booleans in JSON.
