Why convert JSON to CSV?
- Spreadsheet-ready. Open API data in Excel, Google Sheets, or Numbers as rows and columns.
- Pipeline-friendly. Feed flat CSV into databases, BI tools, and data-science workflows.
- Flattens nesting. Nested objects become dotted columns, so deep JSON still fits a table.
How it works
- Use the converter. Go to the Formatly JSON to CSV converter page. No registration is required.
- Upload your JSON file. Drag and drop your JSON document into the uploader, or browse from your device.
- Convert to CSV. Select CSV as the target format and click the Convert button.
- Download the CSV file. Click the Download button to save the converted CSV spreadsheet.
Good for
- Importing API responses into a spreadsheet.
- Loading JSON into a database or BI tool.
- Reviewing structured data as a flat table.
FAQ
How does the converter handle nested JSON structures? Our parser recursively flattens nested JSON dictionaries into flat headers separated by dots (e.g. 'user.profile.name'), mapping them directly into a two-dimensional CSV structure.
Will arrays or lists stay formatted correctly? Single values or lists of primitives are converted to string format, while arrays of objects are structured in flat rows using their child keys.
Is my data uploaded to servers safely? Yes, we prioritize security. All uploads and generated files are automatically and permanently deleted from our servers after exactly 1 hour. No backups, cache, or logs are retained.
