Outlook contacts to CSV — from a .pst, without Outlook
Get the contacts out of an Outlook .pst or .ost file as a CSV table — no Outlook installed, nothing uploaded.
About this conversion
Outlook can export its contacts to CSV, but only while it is installed, running and attached to the mailbox. After a job ends or a computer dies, what is left is the .pst file. The page opens it directly and lists the contacts: names, every phone, the email addresses (which Outlook keeps in a separate, numbered property that most viewers miss), home and business addresses. Addresses Outlook remembered by itself from your mail are marked “Suggested by Outlook”, so they can be told apart from people you actually saved.
Just want to look inside it?
The same tool without converting anything: open the file and read it.
The same contacts, any way out
The file is read once and stays open, so the format is picked at the end: the same list
can leave here as XLSX, CSV for Google Contacts, CSV for Outlook, VCF or PDF. Before that you can search it, see which people are saved
twice — the same number written as (555) 201-4477 in one file and
+15552014477 in another counts as one — and fold the duplicates into a single
card without losing any phone, address or note.
Questions
- Do I need the password of a protected .pst?
- No. That password guards the Outlook window, not the data inside the file.
- Is the mail in the file shown too?
- Yes, on its own tab. This page opens the Contacts tab first; the Mail and Calendar tabs are a click away.
- Which CSV layout is it?
- A readable table. For a file Outlook or Google will import back, use one of the two “CSV for Outlook” options or “CSV for Google Contacts” in the Export menu.
