JSON to CSV Converter
Convert a JSON array of objects to CSV - correctly quotes values containing commas, quotes, or newlines.
Paste a JSON array of objects below - this tool derives CSV columns from the object keys and produces correctly-quoted CSV output.
For nested objects/arrays within your JSON, see the Data Integrity notes below on how they're represented in flat CSV cells.
What Input Does This Expect?
An array of JSON objects (like [{"name": "Jane", "age": 30}, ...]) - each object becomes one CSV row, and column headers are derived from the union of all objects' keys.
Why Use This Tool?
Producing correctly-quoted CSV by hand is easy to get subtly wrong - any value containing a comma, quote, or newline needs proper CSV quoting/escaping, which this tool handles automatically.
How to Use It
- Paste a JSON array of objects.
- Click Convert.
- Copy or download the resulting CSV.
Data Integrity Notes
Nested objects or arrays within a field are serialized as a JSON string within that CSV cell, since CSV itself has no concept of nested structure - this preserves the data rather than silently discarding it, though it means that cell isn't plain flat text.
