How to use this tool
What this tool does and how it can help.
JSON to CSV conversion takes tabular-friendly arrays and turns them into comma-separated values you can open in spreadsheets, scripts, or reporting tools.
This tool is designed for API-style JSON arrays where each item is a flat object. It creates a header row from discovered keys and aligns each object to those columns.
You can use the result to quickly export data for analysis, dashboards, or spreadsheet imports without opening another app first.
Processing happens directly in your browser, and your JSON never leaves your device.
FAQ
- Is my JSON uploaded anywhere?
- No. The conversion runs entirely in your browser, and your data is not sent to a server.
- What kind of JSON is supported?
- This tool supports top-level arrays of objects. Nested values are converted into JSON strings, and any differing keys are included as additional columns.
- Can I open the CSV in Excel or Google Sheets?
- Yes. Downloaded CSV files can be opened in Excel, Google Sheets, and other spreadsheet tools.
