How to Convert JSON to CSV
JSON to CSV
When to Convert JSON to CSV
Convert JSON arrays of objects to CSV when exporting API data to spreadsheets, sharing reports with non-developers, or importing into tools that expect tabular input.
Real-World Examples
[{"id":1,"name":"Ada"},{"id":2,"name":"Lin"}] → two-row CSV with headers id,name
Single objects converted to one CSV row
Values with commas or quotes properly CSV-escaped
Common Mistakes
- Passing nested objects that flatten unpredictably in CSV
- Expecting arrays of primitives to become columns without objects
- Assuming all CSV dialects use comma separators (this tool uses commas)
Developer Tips
- Flatten nested objects before conversion if you need flat columns
- Validate JSON first to catch syntax errors early
Frequently asked questions
What JSON shape is supported?
An array of objects or a single object. Each object becomes one CSV row.
How are headers determined?
Headers are the union of all object keys across rows, sorted by first appearance.
Are nested objects supported?
Nested values are converted with default string coercion. Flatten complex nested data first for best results.
