Frequently Asked Questions
Find answers to common questions about our JSON to CSV converter
What JSON formats are supported?
Our converter supports both JSON arrays of objects and single JSON objects. The tool will automatically wrap single objects in an array for proper conversion.
Is there a size limit for the JSON input?
The tool processes data in your browser, so very large files (over 10MB) might cause performance issues depending on your device. For optimal performance, we recommend splitting very large datasets.
How are nested JSON objects handled?
Nested objects and arrays are flattened to string representation in the CSV output. For complex nested structures, you might need additional processing after conversion.
Can I specify which fields to include in the CSV?
Yes, you can specify headers in the optional 'Custom Headers' field. Enter comma-separated field names to include only those fields in your CSV output.
Is my data secure when using this tool?
Absolutely. All processing happens locally in your browser. Your data never leaves your device or gets sent to any server.
