Frequently Asked Questions

How do I convert nested JSON to CSV?▼

Our tool automatically flattens nested JSON objects. For complex nested structures, the converter will create column names using dot notation (e.g., "user.address.city"). Arrays within objects are handled intelligently to preserve data integrity.

What's the maximum file size I can convert?▼

Free users can convert files up to 10MB. PRO users enjoy unlimited file sizes. Since conversion happens in your browser, the actual limit depends on your device's available memory.

Can I convert JSON arrays with different structures?▼

Yes! Our converter handles JSON arrays where objects have different properties. It will create columns for all unique properties found across all objects, filling empty cells where properties don't exist.

How do I handle special characters in CSV output?▼

The converter automatically handles special characters, quotes, and commas by following CSV standards. Fields containing commas or quotes are properly escaped and wrapped in quotes to ensure data integrity.

Is my data secure during conversion?▼

Absolutely! All conversions happen entirely in your browser using JavaScript. Your data never leaves your device, is never uploaded to any server, and is never stored anywhere. This makes it completely safe for confidential or sensitive data.
