Why convert YAML to CSV?
YAML configs often describe lists of records. CSV is the fastest path into spreadsheets when you only need flat columns.
What changes in the output
- Root must flatten to tabular JSON (object or array of objects)
- Nested fields use dot notation in column headers
- Arrays in cells are JSON-encoded strings
- Only a single YAML document is supported
