JSON → CSV
Paste a JSON array to convert it to CSV format.
About the JSON to CSV converter
This tool converts JSON data to CSV instantly. It is useful for opening API responses and JSON datasets in Excel, Google Sheets, or any spreadsheet application.
Nested objects are flattened into path-style column names (like address.city) because CSV is a flat, tabular format. The conversion runs entirely in your browser, so your data is never uploaded to a server — safe for confidential datasets.
How to use it
- Paste your JSON data into the input panel.
- The converted output appears automatically.
- Review the result and adjust the input if needed.
- Copy or download the CSV output.
Frequently asked questions
Is my data uploaded anywhere?
No. The conversion happens locally in your browser; nothing is transmitted or stored.
Is there a file size limit?
No fixed limit — files of several megabytes convert in seconds since everything runs on your device.
What happens to invalid JSON input?
The tool reports a clear error instead of producing broken output, so you can fix the input and retry.
Can I convert in the other direction?
Yes — the JSON converter section includes tools for both directions between JSON, CSV, TSV, XML, and YAML.
