How it works
Object keys become CSV headers; nested objects and arrays are represented as JSON strings within their cell.
Common use cases
- Exporting API data to a spreadsheet
- Preparing data for import into other tools
Frequently asked questions
- What happens to nested objects?
- Deeply nested values are shown as their JSON string representation in the cell, since CSV has no native nesting.
