Tips & Best Practices
Use Flatten for Nested Data
Enable 'Flatten nested' to convert nested objects like {address: {city: 'NYC'}} into flat columns like address.city.
Try Different Delimiters
If your CSV doesn't open correctly in Excel, try using semicolon delimiter instead of comma, especially for European locale settings.
Array Values
Arrays within objects are converted to JSON strings in the CSV. For better results, ensure your data is a flat array of objects.
