Frequently Asked Questions

The converter expects a YAML array of objects (a list of records). Each object's keys become CSV column headers, and values become row data. Simple key-value YAML maps are converted to a two-column CSV.

Nested objects are flattened using dot notation. For example, address.city becomes a column header 'address.city'. Arrays within values are joined with semicolons.

The default output is comma-separated. You can also choose tab or semicolon as the delimiter for compatibility with different spreadsheet programs.
