JSON to CSV Converter

What is JSON to CSV Converter?

JSON to CSV conversion transforms structured JSON data (arrays of objects or nested objects) into flat, tabular CSV format. Each JSON object becomes a row, and object keys become column headers. This conversion is useful when you need to export JSON data to spreadsheet applications, import into systems that only accept CSV, or create reports from API responses.

Common Use Cases

• Data export - convert API responses to CSV for spreadsheet analysis
• Report generation - transform JSON data into CSV reports
• Legacy system integration - convert JSON to CSV for older systems
• Data analysis - export JSON data to Excel or Google Sheets
• Database exports - convert JSON query results to CSV
• Backup and archival - store JSON data in CSV format
• Data sharing - convert JSON to CSV for non-technical users

How It Works

The JSON to CSV converter takes JSON input (typically an array of objects) and extracts all unique keys from the objects to create column headers. Each object in the array becomes a row, with values placed in columns corresponding to their keys. The converter handles special characters by properly quoting values, escapes commas and quotes within values, and flattens nested objects when possible. You can customize the delimiter (comma, semicolon, tab) and control how nested data is handled.

Examples

[{"name":"John","age":30},{"name":"Jane","age":25}]

John,30
Jane,25

[{"user":{"name":"John"},"score":100}]

user.name,score
John,100
