Can I open the generated CSV in Microsoft Excel or Google Sheets?

Yes. The output conforms strictly to RFC 4180 standards. Double quotes and cells containing commas or line breaks are properly escaped so that Excel, Numbers, and Google Sheets render them cleanly without column shifts.

How does the converter handle missing or mismatched keys?

The converter extracts the union of all keys found across all objects in your JSON array. If certain objects lack particular keys, those cells are rendered as empty, maintaining aligned rectangular tables.

How are nested objects or arrays handled in CSV cells?

Nested child objects or array values are serialized into clean JSON strings within the cell, enclosed in escaped quotes.
