JSON to CSV — Complete Guide
JSON to CSV conversion is useful when you need to bring JSON data into a spreadsheet, export API response data for analysis, or prepare data for a system that expects CSV format. This tool flattens a JSON array of objects into a CSV table where each object becomes a row and each unique key becomes a column.
What you can do with JSON to CSV
- Exporting API response data into a spreadsheet for analysis or reporting
- Preparing JSON data for import into database systems that accept CSV
- Converting application data dumps into a format stakeholders can work with in Excel
- Sharing data with non-technical colleagues who work in spreadsheet applications
How to use JSON to CSV
Paste a JSON array of objects into the input field
The tool generates a CSV table with the JSON keys as column headers
Copy or download the CSV output
Tips for best results
Input should be a JSON array of objects — all objects should ideally share the same keys
Nested objects are not automatically flattened — deeply nested JSON may need to be simplified first
Values containing commas are automatically wrapped in quotes in the CSV output

Frequently asked questions
What if my JSON objects have different keys?
The tool typically uses the union of all keys as columns. Objects missing a particular key will have an empty cell in that column.
How are nested objects handled?
Most simple converters serialize nested objects as stringified JSON in a single column. For complex nested data, consider flattening the structure before converting.
