JSON to CSV Converter

What JSON to CSV does

This tool converts a JSON array of objects into CSV format, using the object keys as column headers — the reverse of the more common CSV-to-JSON conversion, useful when you need tabular data out of an API response.

How to use it

1. Paste a JSON array of objects into the box.
2. Click Convert to CSV.
3. Click Copy CSV to copy the resulting table.

Common uses

• Converting an API response into a spreadsheet-friendly CSV for analysis.
• Preparing JSON data for import into Excel, Google Sheets, or a database tool.
• Turning a JSON export from an app or database into a report-ready table.
• Sharing structured JSON data with a colleague who works primarily in spreadsheets.
• Quickly inspecting the shape of a JSON dataset in tabular form.

Good to know

Every object in the array should ideally have the same set of keys for a clean conversion — if objects have inconsistent fields, some cells in the resulting CSV may come out empty for rows missing that particular key, which is expected behavior rather than an error.

Converting structured JSON data back into flat CSV rows necessarily loses some information if the original JSON contains nested objects or arrays within a field, since a spreadsheet row can't naturally represent a nested structure the way JSON can — this is an inherent limitation of the CSV format itself, not a flaw in the conversion process, and it's worth checking the output if your source JSON has deeply nested fields.
