How do you extract phone numbers from email bodies in Outlook? - regex

Question

I have a pretty large account full of ~20k emails in Outlook and I need to extract phone numbers from those emails.
An example of an email would be:
From: Amy Schwartz <amy#blahdyblah.com>
Dear Anatoliy,
I want you to do blahdy blahdy blah.
Amy Schwartz
[phone] <---- I want this
Blahdy Blah Company
The idea is to go through every email and match the last Phone number via regex and export a list in the following format:
Name: Name from the "From" field
Email: Email from the "From" field
Phone: The last phone number matched in the email text
Do you have any ideas on how to go about doing this?
UPDATE: Didn't find any prebuilt solutions, but I'm hacking together my own using this. codeTwo Outlook Express. You can export any email field (body, HTML body, from, from name) to CSV. It's a little slow (3 seconds a message on my i7 iMac running a Win7 VM). But it works :) And from there I will probably just put in a database and do some regex magic. Will post process once I'm done.

Figured it out. It's super easy if you know how to make a Node.js script (but I'm sure you can write one in Bash).
1) Use Outlook Export plugin to export all your emails to a CSV. Make sure email is first column, name is second column, and Body (text) is 3rd column.
2) Write the following script in Node JS in the same directory as you CSV of emails
var fs = require('fs');
var csv = require('csv');
csv()
.from.stream(fs.createReadStream(__dirname+'/data.csv'))
.to.path(__dirname+'/out.csv')
.transform( function(row){
var match = row[2].match(/(?:\+?1\s*(?:[.-]\s*)?)?(?:\(\s*([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9])\s*\)|([2-9]1[02-9]|[2-9][02-8]1|[2-9][02-8][02-9]))\s*(?:[.-]\s*)?([2-9]1[02-9]|[2-9][02-9]1|[2-9][02-9]{2})\s*(?:[.-]\s*)?([0-9]{4})/);
return '"' + row[0] + '","' + row[1] + '","' + (match ? match[0] : '') + '"\n';
})
.on('error', function(error){
console.log(error.message);
});
and run it using node script.js.
And that's it! Runs super quickly (~20 secs for 20k emails).
Let me know if you have any suggestion (or package this into a downloadable executable)
