Convert a JSON object or JSON array of objects into CSV with a side-by-side browser workflow.
Convert JSON records into CSV without leaving the browser
Paste a JSON object or array of objects on the left, review the CSV output on the right, and keep both views visible while you prepare exports, spreadsheet imports, or tabular developer fixtures.
Arrays and objects stay in one cell as compact JSON strings instead of being flattened automatically.
CSV output updates as soon as the JSON input is valid.
Converted CSV output will appear here when the JSON input is valid.
Status
Column order follows the first time each key appears across the current records.
How to use the JSON to CSV converter
- Paste one JSON object or an array of JSON objects into the input panel on the left.
- Choose the CSV delimiter you want to use, such as comma, semicolon, or tab.
- Review the generated CSV output on the right side.
- Copy the CSV text or download it as a file when the result matches the structure you need.

What this JSON to CSV converter does
This tool converts browser-pasted JSON records into CSV with a header row and one output row per object. It is useful when you need to move API payload samples, structured fixtures, or export-ready records into a format that spreadsheets, reports, or import tools can read more easily.
How keys, columns, and nested values are handled
Column order follows the first time each key appears across the current records. That means if later rows introduce new keys, those columns are appended instead of reshuffling the earlier order.
Nested arrays and objects are kept inside one CSV cell as compact JSON strings. This first release avoids forcing a flattening scheme that may not match your target system while still producing a usable CSV export.
When JSON to CSV is useful
A JSON-to-CSV step is useful when you need to share API records with non-technical teammates, inspect structured test data in a spreadsheet, prepare import files, or compare objects in a simple tabular view. Because the conversion runs in the browser, you can inspect the result immediately before copying it into another workflow.
JSON to CSV converter FAQs
Does this tool support a single JSON object?
Yes. A single JSON object is treated as one CSV row with a header row above it.
What happens if later records contain new keys?
The converter appends new columns in the order those keys first appear, so earlier headers stay in place.
How are nested arrays and objects handled?
Nested arrays and objects are serialized as compact JSON strings inside one CSV cell instead of being flattened automatically.
