Why Use Our JSON to CSV Converter
Turn any JSON into spreadsheet-ready CSV in seconds
Any JSON Shape
Handles arrays of objects, arrays of arrays, and single objects. Keys become columns automatically — even when records have different fields.
Spreadsheet-Ready CSV
Get clean CSV you can open in Excel or Google Sheets, with your choice of comma, semicolon, or tab delimiter.
100% Private
Your JSON is parsed entirely in your browser. Nothing is uploaded, stored, or tracked — safe for API responses and exports.
Built for Real-World JSON
A fast, private converter that handles whatever shape your JSON takes
Smart JSON Parsing
Accepts arrays of objects, arrays of arrays, a single object, or JSON that wraps its data in a property like { data: [...] }.
Automatic Columns
Builds the header row from the union of all keys, so records with missing or extra fields still line up correctly.
Paste or Upload
Paste raw JSON or upload a .json file. Either way, conversion is instant.
Choose Your Delimiter
Output as comma, semicolon, or tab-separated values to match the locale or tool you're importing into.
Copy or Download
Copy the CSV to your clipboard or download it as a .csv file with one click. Quoting and escaping are handled for you.
Browser-Only & Private
Everything runs locally in your browser. Your JSON never reaches a server.
Frequently Asked Questions
Everything you need to know about converting JSON to CSV
Converting JSON to CSV takes seconds:
- Paste your JSON or upload a .json file
- Click "Convert to CSV"
- Pick a delimiter, then copy or download the CSV
The tool builds the header row from your object keys and maps each record to a row automatically.
It handles every common shape:
- An array of objects — the typical API response
- An array of arrays
- A single object (becomes one row)
- JSON that wraps its array in a property, e.g.
{ "data": [ ... ] }
CSV is flat, so a nested object or array inside a field is kept as a compact JSON string in that cell — the data is preserved without breaking the table. Top-level keys always become their own columns.
No problem. The converter uses the union of all keys across every record for the header row. Missing fields become empty cells; extra fields add new columns — everything stays aligned.
No. Everything runs in your browser — your JSON is never uploaded or stored, so it's safe for API responses and exports. See our Privacy Policy.
Yes — comma, semicolon, or tab. Cells containing the delimiter, quotes, or line breaks are automatically quoted and escaped so the CSV stays valid.
This tool goes JSON → CSV. To work with CSV data, try our CSV viewer or the CSV to Excel, Word, PDF, HTML, and Markdown converters.
Yes — completely free, with no registration, no limits, and no paywalled features.

Turning JSON Into Spreadsheet-Ready CSV
JSON Is for Machines, CSV Is for Spreadsheets
APIs, databases, and config files speak JSON — nested, structured, and great for code. But the moment you need that data in Excel, Google Sheets, or a BI tool, you need rows and columns. CSV is the bridge, and converting between the two is a constant, everyday chore.
The Manual Conversion Trap
Writing a one-off script to flatten JSON works until the data shape changes — a new field, a missing key, a wrapped array — and the script breaks. Doing it by hand for anything beyond a few records is slow and mistake-prone.
Paste JSON, Get CSV
This converter reads whatever shape your JSON takes, builds the columns from the union of all keys, and outputs valid CSV you can copy or download. Records with different fields line up, and nested values are preserved as JSON inside their cell.
Where It Helps
Pulling an API response into a spreadsheet, handing a non-technical teammate data they can open in Excel, loading records into a tool that only accepts CSV, or quickly eyeballing a JSON export as a table — all without writing code.
Private by Design
Because the conversion runs in your browser, you can turn API responses, customer records, or internal exports into CSV without any of it ever reaching a server.
