JSON conversion checks

Requires a JSON array of objects so columns are deterministic.
Collects headers across mixed object shapes and can flatten nested objects into dotted keys.
Reports typed errors for empty input, invalid JSON, and non-tabular JSON shapes.
Escapes CSV cells safely for quotes, newlines, carriage returns, and selected delimiters.

Runs in your browser

JSON to CSV conversion runs locally in your browser. Shared links only include JSON input when you explicitly opt in.

Include current input in shared/debug payload

JSON to CSV converts arrays of JSON objects into comma-separated table data.

It helps move API responses, exports, and structured records into spreadsheets, notebooks, and reporting tools.

The browser parses JSON, collects object keys, optionally flattens nested objects, and writes rows in CSV format.

Use a JSON array of similarly shaped objects for the cleanest table.

Nested objects can be flattened into dotted columns, but arrays are stringified and should be reviewed.

Conversion happens locally in your browser.

CSV is a flat format, so nested JSON, arrays, and mixed object shapes may lose structure or need manual cleanup.

Yes. Copy or download CSV and open it in spreadsheet software.

Flatten nested objects into dotted keys, then review arrays and deeply nested values.

Export API data to spreadsheets

Convert JSON responses from APIs into CSV format for analysis in Excel, Google Sheets, or BI tools.

Prepare structured data for non-technical users

Transform JSON data into CSV so stakeholders can easily open and filter it in spreadsheet software.

Convert database exports between formats

Turn JSON exports from NoSQL databases into CSV for use with traditional reporting tools.

Move between CSV, JSON, JSONL, TSV, and Markdown table formats while keeping pasted table data local to the browser.
