📝 Tips & Notes

📊 Array vs Object

JSON arrays are converted to table rows. JSON objects become single-row CSV with keys as columns.

🔍 Nested Objects

Nested objects are flattened with dot notation (e.g., address.city becomes "address.city").

📋 Excel Compatibility

For best results with Excel, use comma delimiter and open the CSV directly in Excel.
