Why convert MSG to CSV?
An .msg file is a single saved Outlook email in a proprietary binary OLE container; CSV is a plain-text tabular format used in spreadsheets and databases. The main use case is e-discovery, archiving, or migration audits - turning dozens or hundreds of emails into a searchable flat table of sender, recipient, subject, date, and body text that loads directly into Excel or any database.
