How CSV to YAML conversion works

The first row of your CSV is used as field names (keys). Each subsequent row becomes a YAML mapping under a sequence dash (-). Numbers, booleans (true/false), and null values are auto-detected; strings containing special YAML characters are quoted.

To convert YAML back to CSV, try YAML to JSON then JSON to CSV. To convert CSV to JSON directly, use CSV to JSON Converter.
