Paste your JSON data

Configure CSV options
Choose the delimiter (comma, semicolon, tab), whether to include a header row, and how to handle nested objects. Nested JSON objects can be flattened into dot-notation column names.
Convert to CSV
Click Convert to generate the CSV output. The tool maps JSON keys to column headers and values to rows. Preview the result in a table view to verify correctness.
Download the CSV
Download the CSV file or copy the text output. The file is ready to open in Excel, Google Sheets, LibreOffice, or any spreadsheet application.
Pro Tips
- Flatten nested JSON structures before converting for the cleanest CSV output.
- If your JSON has inconsistent keys across objects, the CSV will include all keys with empty cells for missing values.
- Use semicolons instead of commas as delimiters if your data contains commas in field values.
Common Issues & Fixes
Issue: Nested JSON objects appear as [Object] in the CSV.
Fix: Enable the "flatten nested objects" option to convert nested structures into dot-notation columns (e.g., address.city).
Issue: The CSV has extra quotation marks around values.
Fix: This is standard CSV formatting for values containing commas, newlines, or quotes. Most spreadsheet apps handle this correctly on import.
