Frequently Asked Questions
What JSON format does this converter accept?
This converter accepts JSON arrays containing objects. Each object in the array represents a row in the CSV output, and the object keys become the CSV column headers. For example: [{"name": "John", "age": 30}, {"name": "Jane", "age": 25}]
How does the converter handle nested objects or arrays?
Nested objects and arrays are automatically converted to JSON strings in the CSV output. This ensures all data is preserved while maintaining CSV compatibility. The nested data is properly escaped with quotes.
Can I use this tool to export data to Excel?
Yes! The CSV format is fully compatible with Microsoft Excel, Google Sheets, and other spreadsheet applications. Simply download the CSV file and open it in your preferred spreadsheet software.
Is my data safe when using this converter?
Absolutely. All processing happens entirely in your browser using JavaScript. No data is ever sent to our servers. Your JSON data stays on your device, ensuring complete privacy and security.
What happens if my JSON objects have different keys?
The converter automatically collects all unique keys from all objects in the array to create the CSV headers. If an object is missing a key, that cell will be empty in the CSV output.
