Show HN: Export contacts from Outlook for Mac (.olm) (local, open source) (github.com)

2 points by emiliano 5mo ago ↗ HN

Hi HN,

I built this while helping a colleague migrate away from Outlook for Mac after a company acquisition. Outlook only exports contacts as .olm, and most tools we found were either paid or required uploading the data somewhere

Since emails and contacts are a pretty sensitive topic, I didn’t like that, so I put together a small local tool instead

It extracts contacts from an Outlook for Mac .olm file and exports them as CSV or vCard. There’s a CLI, plus a simple web UI that runs entirely client-side

Hope it helps someone else

This is exactly right. Client-side processing for sensitive data like contacts eliminates the trust problem entirely. Most migration tools want you to upload your entire contact database to some random server when the extraction can happen locally in milliseconds.

Pure client-side tools like this should be an option for any personal data processing.

This is what I have done for my users: an option to import their emails to an in-browser db for guaranteed privacy.
