Frequently Asked Questions about JSON to CSV Converter - Export Clean Spreadsheets Free Online

How does Convertify handle nested JSON objects?

Nested objects are flattened using dot notation (e.g., address.city becomes a column header). This gives you a clean, flat CSV that's easy to work with in Excel or Google Sheets.

What JSON structures are supported?

Convertify handles arrays of objects (most common), single objects, and deeply nested structures. It auto-detects the data shape and produces the most logical tabular layout.

Can I choose which fields to include in the CSV?

Yes. After uploading your JSON, you can select or deselect specific fields to include in the output. This is useful for large JSON files where you only need certain columns.
