How to use the JSON to CSV converter.
Calculate and review
Use the main action when needed. Object keys become columns, arrays receive generated headings, nested values are serialised, and cells are quoted where the delimiter or line breaks require it.
Try a worked example
Paste an array of customer objects to create a header row containing every property found across the records.
Check the assumptions
Deeply nested data is not fully flattened. Text beginning with spreadsheet formula characters is prefixed for safety and may need review for another destination.
