Convert Outlooks’ horrendous .pst file to standard .vcf vCard and import to any vCard compatible client (your phone, radicale, thunderbird, etc.)

Why I made this?

I decided to move my whole org to ThunderBird to be free from forced proprietary formats. And I created this Java CLI app (Because Java had the java-libpst to work with PST files) to do it. I converted ~500 contacts successfully and we are free from Outlook at last.

This has worked for us, and I tried to make it as robust as possible. If you see any issues, please open an issue or PR.

LLM disclaimer: I used OpenCode + BigPickle to create this but I wouldn’t call it vibecoded. I spent ~2 days on it so far and let the LLM help me. Hope it helps.
