[rosariocontarino975]

You cannot open an OLM file directly in Excel because OLM is a Mac Outlook data format. To view its contents in Excel, you first need to convert the OLM file into a CSV file. CSV is supported by Excel, Google Sheets, and many other applications.

The simplest way to do this is by using a dedicated tool like Advik OLM to CSV Converter, which extracts emails, contacts, and other mailbox data from OLM files into a clean CSV format without needing Outlook.

Here’s How to Do It:​

1. Install Advik OLM to CSV Converter on your Windows PC.
2. Click Add File and browse to your OLM file.
3. Select the folders you want to view in Excel (Inbox, Sent, Contacts, etc.).
4. Choose CSV from the output formats.
5. Pick a location to save the CSV file.
6. Click Convert to start the process.

Open the CSV in Excel:​

1. Go to the folder where the CSV file is saved.
2. Double-click the CSV file.
3. Excel will open it automatically and display all the email details (To, From, Subject, Date, etc.).

Why This Method Works​

• No need for Outlook (Mac or Windows)
• Converts large OLM files safely
• Keeps data structure intact
• Lets you analyze emails and contacts directly in Excel

Using CSV format makes it easy to sort, filter, and organize your OLM data inside Excel, helping you work with your mailbox information effortlessly.
