About this tool

1
Paste or upload JSON
Paste a JSON array of objects into the input area or upload a .json file.
2
Select fields to include
Choose which object keys should become CSV columns, or include all fields by default.
3
Configure CSV options
Set the delimiter, choose whether to include a header row, and select a line ending format.
4
Download the CSV
Copy the result or download the generated .csv file.

Flatten nested JSON objects first for cleaner CSV output - nested values are serialized as strings otherwise.
Use tab as the delimiter if you plan to paste the result directly into Excel or Google Sheets.
If your JSON contains arrays as values, they will be joined with a separator in the CSV cell.
Check for inconsistent keys across objects - missing keys will produce empty cells in those rows.

Automatically extracts column headers from JSON object keys
Handles nested objects with dot-notation flattening
Configurable delimiter, quoting, and line endings
Supports JSON arrays and newline-delimited JSON (NDJSON)

The input must be an array of objects (e.g., [{...}, {...}]). Each object becomes one CSV row, and the keys become column headers.

Nested objects are flattened using dot notation (e.g., address.city becomes a column header). Deeply nested structures are serialized as JSON strings.

Yes. After the fields are extracted, you can drag to reorder them or manually specify the column order before exporting.
