CSV or Comma-Separated Values file stores tabular data as a plain text. Where each field separated by commas and each record is placed on a new line; however, this is not always the case. CSV format also supports multi-line strings as long as string enclosed in double-quotes.
This would be a valid CSV file and this is not unusual. Specifically, behavior can be observed during report exporting where custom or a standard text field such as "notes" or "address" is present and contain multi-line text.
