So, for anyone expereincing problems, here's what I did:
1. Copied the list and took it over to Notepad++.
2. Pasted the list in a new .txt document.
3. Press Crtl + H.
4. This screen comes up. Type "\r" in the "
find what" field.
5. Put a comma in the "
replace with" field.
6. In the "search mode" panel on the bottom, make sure "
Extended" is selected. The click replace all.
Make sure to put on comma on the very last line of the text file.
However: If you're out of invitations, this won't work. So, here's what I did to get around that:
1. Log in to an aged g-mail account that's connected to your Linkedin.
2. Go to Contacts.google.com and export your contacts list as a CSV file.
3. Open the CSV file and paste all of the emails from this list above to the column "
E-mail 1 - Value", which looks like:
4. Save the CSV file and head back over to Contacts.google.com and import your newly saved CSV file.
5. Now go back over to Linkedin and attempt to send invites via the gmail contacts option.
I followed these steps a few weeks ago and this is what I got:
Good luck and happy invites!
