JSON to CSV converter JSON to CSV converter

Convert JSON to CSV online

Paste a JSON array or object and get a CSV table that can be copied into spreadsheets and data tools.

Nested values are kept as JSON strings so the generated CSV remains readable and predictable.

The tool runs directly in the browser and is ready for quick checks without installing software.
Input can be cleared and recalculated immediately, which is useful for repeated small tasks.
Use fullscreen mode when you need more space for long text, structured data or large result blocks.
Copy buttons are available on generated output so results can be reused in code, documents or support chats.
Most operations are deterministic: the same input and options produce the same output.
For sensitive content, prefer local browser tools and review the result before sharing it further.
