About this tool
Convert JSON objects into CSV format when you need lightweight exports for spreadsheets, docs, or manual review.
JSON to CSV Converter is aimed at the opposite direction: taking object data and flattening it into a spreadsheet-friendly format for exports, handoff, and manual review. It is especially helpful when someone needs a quick table version of API data without opening code or a data toolchain.
- Flattens nested objects with escaped dot paths or preserves nested objects and arrays as JSON cells without emitting [object Object].
- Uses Papa Parse 5.5.3 for delimiter quoting and optional spreadsheet formula protection, then reparses output to verify rows and columns.
- Controls comma, semicolon, or tab delimiters, CRLF or LF, UTF-8 BOM, null text, and deterministic column ordering.
How to use JSON to CSV
Paste a JSON object or array of objects, review the generated header row, and then copy the CSV into Sheets, Excel, Airtable, or another import flow. For nested data, flatten the objects first or test a small sample so you know exactly how the exported columns will look.

Examples you can test
Load an example, compare the result with the expected output, then replace it with your own input.
Export users to rows
Example input
[{"name":"Ada","role":"admin"},{"name":"Grace","role":"editor"}]Expected output
name,role Ada,admin Grace,editor
Flat arrays of objects convert cleanly to spreadsheet-style rows.
Review API response data
Example input
[{"id":42,"status":"paid","total":120}]Expected output
id,status,total 42,paid,120
CSV output is useful for manual review, support handoff, and simple imports.
Validation checklist
- Flatten nested objects before converting when the destination expects simple columns.
- Check column order and missing fields before importing into a spreadsheet.
- Review quoting when values contain commas, line breaks, or quotation marks.
