Tabular data often needs to move between JSON (for APIs and code) and CSV (for spreadsheets and analysts). This tool converts a JSON array of objects into CSV, and converts CSV back into JSON, instantly and locally.
How to use it
- Paste a JSON array of objects, or CSV.
- Choose the direction (JSON→CSV or CSV→JSON).
- The converted result appears.
- Copy it.
About JSON to CSV Converter
Developers constantly bridge two worlds: APIs speak JSON, while business users live in spreadsheets that want CSV. Converting between them by hand is impractical for anything but a few rows. This tool flattens a JSON array of objects into a CSV table with a header row, and parses CSV back into structured JSON. It is ideal for exporting API data for a colleague, or importing a spreadsheet into code. Conversion runs entirely client-side, so your data stays private.
FAQ
What JSON shape does it expect?
An array of flat objects, like [{"name":"A","age":1},...]. The object keys become the CSV columns.
Does it handle commas inside values?
Yes. Values containing commas or quotes are properly quoted in the CSV output.
How are nested JSON objects handled when converting to CSV?
CSV is a flat format, so deeply nested objects are flattened or serialised into cells. For best results, convert a JSON array of flat objects where each object has the same keys, which map cleanly to CSV columns.
