How to use JSON to CSV Converter

Upload a JSON file containing an array of objects, or paste JSON into the input area. The converter creates columns from object keys and serializes nested values as JSON strings.

Supported workflow and limitations

The primary supported structure is an array of objects. Deeply nested objects are serialized into individual cells rather than expanded into relational tables. Missing properties become empty cells.

Privacy and file handling

Your selected files are processed in your browser. ProTools does not require you to upload them to a document-processing server. Required JavaScript libraries and language data may be downloaded from their respective CDNs. Analytics and advertising are controlled separately by your cookie preferences.

Frequently asked questions

What JSON structure is supported?

The converter expects an array of objects, such as [{"name":"Ada","role":"Engineer"}].

How are nested values handled?

Nested objects and arrays are serialized as JSON text inside a cell to avoid losing their structure.

Can I paste JSON instead of uploading a file?

Yes. Paste valid JSON into the editor and choose Convert.
