Frequently Asked Questions
❌ Why am I getting "JSON must be an array of objects" error?
This error occurs when your JSON doesn't contain a suitable array structure. Our tool looks for arrays of objects with consistent properties. Try restructuring your data or use nested arrays within your JSON.
🔧 How do I handle nested JSON objects?
Our converter automatically flattens nested objects using dot notation. For example, {"user": {"name": "John"}} becomes a column named "user.name". Enable the "Flatten nested objects" option for best results.
🔒 Is my data secure during conversion?
Absolutely. All conversions happen in your browser using client-side JavaScript. Your data never leaves your computer and is not stored on our servers. This ensures complete privacy and security.
📊 What file size limits exist?
Since processing happens in your browser, the limit depends on your device's memory. Most modern browsers can handle files up to several hundred MB without issues.
🎯 Why choose CSV over other formats?
CSV is universally supported by Excel, Google Sheets, databases, and data analysis tools. It's lightweight, human-readable, and perfect for tabular data representation.
