JSON to CSV Converter

JSON to CSV Converter — How It Works

This tool accepts a JSON array of objects and converts each object into a row in the CSV file. The keys of the first object are used as column headers, and all objects are scanned to ensure no columns are missed. Nested objects are flattened using dot notation so deeply nested API responses convert cleanly without losing data.

Common Use Cases

• Export API responses to Excel or Google Sheets for analysis
• Convert database query results (exported as JSON) to spreadsheet format
• Transform REST API data for business intelligence tools
• Prepare data for import into CRM or analytics platforms

Supported Input Format

Input must be a valid JSON array of objects: [{...}, {...}]. Each object can have different keys — missing values are left empty in the CSV. Nested objects are automatically flattened.
