JSON to CSV Converter
Convert a JSON array to CSV format — automatically extracts field names as headers and formats all values correctly.
What Does This Tool Do?
JSON arrays of objects can be converted to CSV for use in spreadsheets, databases, and data processing tools. This tool takes a JSON array, extracts the keys as column headers, and formats all values as properly escaped CSV.
Key Features
How to Use This Tool
- Paste a JSON array of objects.
- Click Convert (or use fn: auto-convert).
- Copy the CSV output.
How It Works
The JSON is parsed, the keys of the first object become the CSV header row, and each object is mapped to a row with values in the same order. Values containing commas, quotes, or newlines are wrapped in double quotes.
Common Use Cases
Frequently Asked Questions
What if different objects have different keys?
The tool uses the keys from the first object as headers. Objects missing a key will have an empty cell; extra keys in later objects are ignored.
Are nested objects supported?
Nested objects are converted to string using JSON.stringify. For complex nesting, flatten your JSON first.
