How it works

Complete the job in three clear steps

Choose CSV to JSON or JSON to CSV and paste or upload the source data.
Adjust parsing options and review warnings or the converted preview.
Copy the result or download it with the correct file extension.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Questions

About this tool

Can it handle quoted fields and line breaks?

Yes. The converter uses Papa Parse to support standard quoting, delimiters, header rows, and embedded line breaks.

What JSON shape converts best to CSV?

An array of objects works best because each object becomes a row and its keys become columns.
