CSV Output
CSV output will appear here…Supported JSON structure
This converter expects a JSON array where every element is a flat object. Arrays of primitives (strings, numbers) and deeply nested objects are not directly supported — flatten your data first if needed. The converter collects all unique keys across all objects and uses them as CSV column headers.
When to convert JSON to CSV
- Exporting API response data into a spreadsheet for analysis.
- Preparing data for import into a database or CRM that accepts CSV.
- Sharing structured data with non-technical stakeholders who prefer Excel.
- Archiving JSON records in a format compatible with any spreadsheet app.
RFC 4180 compliance
The output follows RFC 4180 — the de-facto standard for CSV files. Fields containing commas, double quotes, or newlines are wrapped in double quotes; any embedded double quotes are doubled. Line endings use CRLF (\r\n) as specified by the standard, ensuring compatibility with Excel, Google Sheets, and most CSV parsers.
