Best Ways to Convert OLM to CSV on Mac & Windows Systems

Does the OLM file only save emails? Well, no, it’s similar to Windows Outlook PST, which stores all data from the mailbox – contacts, calendar, metadata, attachments, etc. But what if you need all this data in a spreadsheet-friendly, universally readable format like CSV? CSV stands for Comma-separated format, which organizes your data in a tabular form, accessible on a spreadsheet. Learn how to convert OLM to CSV without putting important data at risk – manual and professional solutions are explained further. 

Understanding OLM vs CSV

If you are a new reader, go through the section to understand both formats:

• OLM file: This is the archive file used by Outlook for Mac. It stores emails, attachments, contacts, calendars, events, tasks, and more. 
• CSV file: A plain-text, comma-separated format. It stores data organized in rows and columns, easily opened by Excel, Google Sheets, and many CRM tools. 

Hence, OLM is a full Outlook container, and CSV is a simpler tabular export format. This conversion is often needed for exporting important contacts and metadata. 

Real-Time Needs to Convert OLM File to CSV

Discussed below are some real business and enterprise-level reasons why professionals seek OLM to CSV Conversion:

• CRM integration & contact migrations: Suppose your OLM files contain some important contacts and you want to import them to a CRM tool or Excel file. In this case, CSV is an ideal intermediary. 
• Cross-platform accessibility: As you know, OLM is a proprietary file format of Outlook for Mac. Thus, accessing it on Mac, Windows, Linux, Google Sheets, Excel, or many database systems is difficult. Whereas CSV is widely accessible across all devices, making it useful for you.
• Data analysis & reporting: Often, people need to sort, filter, and process some data, like contacts or emails. However, OLM does not enable this; therefore, export data to CSV and open it in a spreadsheet. The application is well known for sorting and filtering data. 
• Backup & Migration Purposes: Nowadays, this is the most common reason why people prefer CSV. A CSV file is lightweight and universally accessible, best for backup. Moreover, it allows moving data from Mac to Windows or other email platforms smoothly.

How to Convert OLM to CSV (Mac & Windows)

What decides which method you should choose for conversion? There are a few factors that you should consider as a smart chooser:

• Volume of files and data
• The platform you use
• Risk and security of data.

Considering all these factors, we have broadly provided two different methods: the manual method and an automated software. 

Method 1: Convert OLM File to CSV on Mac

If you have a small amount of data and just want to export contacts (or basic information) to CSV, try this manual method:

1. Open and log in to Outlook for Mac.
2. Go to File > Import OLM file (if not done already). 
3. In Outlook, go to File and click Export.
4. Choose to export Contacts to a list (.csv or tab-delimited). 
5. Select the destination folder and save the CSV.

Hence, the CSV file is saved on your PC. Open that CSV in Excel or Google Sheets for further use.

Limitations:

• Good to export only contacts and not full mailbox data.
• No batch conversion for multiple OLM files at once.
• It’s a must that Outlook for Mac is installed and working.
• Moreover, it has a risk of missing metadata or attachments.

Note: For many businesses, this method will be too limited— it does not support bulky file conversion. However, it’s worth knowing.

Method 2: Try Automated Software to Convert OLM to CSV

Mostly for business requirements, professionals prefer the Cigati OLM Converter Tool. It supports large volumes of OLM files, multiple mailboxes, collective data transfer (contacts, calendars, emails, & attachments), and cross-platform migration. Where the manual method stands a chance to fail, the automated solution works best. It is risk-free, avoids file corruption, and preserves data integrity. 

Moreover, it offers multiple filters like date range filter, remove duplicates, and folder selection for selective export. Try all these exclusive features with free demo version! 

Steps to Export OLM File into CSV

1. Download and install the OLM Converter Software. Run it.
2. Click Select Files/Select Folder > Add OLM file(s) (single or multiple).
3. Preview the emails and other data inside the OLM. Click Next. 
4. Choose CSV as the output format. Apply any filters for precise conversion.
5. Select the destination folder to save the CSV.
6. Click on Convert to start saving OLM data to CSV.

Once conversion is complete, you can open the CSV in Excel or import it directly into your CRM tool.

Which Method is Best for Mac & Windows?

• On Mac, Outlook for Mac supports OLM, so it’s quite easy to operate the manual method for conversion. However, bulk conversion can still be compromised.
• On Windows, you will have to convert orphan OLM files and thus choose a professional tool. It will process conversion without Outlook for Mac.

Conclusion

To access Mac Outlook data universally across all platforms, convert OLM to CSV. It’s a practical move for business data handling. Evaluate all methods based on data volume, types of data, and platform dependency. The manual method is good for small-scale migration, whereas a professional solution is best for multiple file conversion, cross-platform migration, or critical business data. Make sure no data is at risk, and your workflow is not disrupted.
