When you convert JSON to CSV, the tool maps each object property to a column in your spreadsheet. If you enable flattening, nested properties like address.city become separate columns with dot notation. The delimiter you choose determines how each value is separated — comma is standard for most spreadsheets, but semicolon or tab can be useful for regional formats or specific applications. The header row (if it is enabled) uses the property names as column labels, ensuring that your data is quickly identifiable when opened in Excel or Google Sheets.
