What is JSON to CSV Converter?
JSON to CSV Converter is an online conversion utility that transforms arrays of JSON objects into tabular Comma-Separated Values (CSV) format suitable for spreadsheets and database imports.
How JSON to CSV Converter Works
The tool analyzes the keys across all objects in a JSON array to create a unified set of column headers. It then iterates through each record, mapping values to corresponding columns, escaping quotes, and wrapping fields containing commas in standard RFC 4180 quotation marks.
Key Features
- ✓Automatic column discovery across irregular JSON objects
- ✓Compliant RFC 4180 CSV escaping for quotes, commas, and line breaks
- ✓Export directly to `.csv` file format
- ✓Real-time preview of formatted CSV table
Common Use Cases
- •Exporting REST API data into Microsoft Excel, Apple Numbers, or Google Sheets
- •Converting analytics log exports for statistical reporting and business intelligence
- •Preparing data for legacy CSV batch ingestion workflows

{"id": 1, "name": "Alice", "role": "Engineer"},
{"id": 2, "name": "Bob", "role": "Designer"}
]id,name,role
