Overview

What Is OLM to CSV Conversion?

OLM to CSV conversion takes an Outlook for Mac OLM file and exports each email as a row in a .csv file. Columns typically include From, To, Subject, Date, and body (or preview). CSV opens in Excel, Google Sheets, and other spreadsheet tools for analysis, reporting, and filtering.

Our free OLM to CSV converter processes on your device. You drop .olm file(s), and the tool extracts all emails and builds a single CSV. All processing happens on your device; nothing is uploaded.

Use cases include reporting and analysis, compliance or audit trails, filtering by date or sender in a spreadsheet, and feeding email metadata into other systems. No Outlook for Mac is required — the tool works on any modern platform.
