About this tool
JSON ↔ CSV / XML is a tool for moving data across formats in seconds. A common headache for developers is receiving data as JSON from an API but needing to open it in Excel or Google Sheets, or the reverse: getting a CSV from another team that you need as JSON to import into your system. This tool handles both in a single step.
It supports three core directions:
- json to csv — turns an array of objects into a CSV table you can open directly in Excel or Google Sheets, perfect for reports or sharing with non-technical colleagues.
- json to xml — converts a JSON structure into XML for legacy systems or APIs that still treat XML as the standard.
- csv to json — reads the header row as keys and converts each row into an object, ready to drop into your code or send to an API.
One thing worth knowing: CSV is a flat table of rows and columns, while JSON can nest many levels deep. So when converting nested JSON to CSV, you get the cleanest result with an array of objects that share similar keys. For very complex data, flatten the structure first.
All conversion runs in your browser, so no files are uploaded to a server, keeping it both fast and private. It is free, needs no signup, and requires no extra software to install. Open your browser and start converting. Browse everything on the tools page.

- Can deeply nested JSON be converted to CSV?
