Convert eml files

Does anyone know a way to view and convert possibly malicious .eml-files (maybe into PDF or plain text files or even images)?

The question has already been asked and answered here before:

If they are malicious, try doing it in a VM.

But how to convert them and then use them on your regular machine/phone etc?

Did you read that post in full I shared?

Duplicate of the thread @anon4124882 linked, but leaving this thread up due to their additional tip of using a VM.
