If I am not mistaken, You want to add people based on the email addresses you have.
If that's the case, its really simple. Go to add connection>Click any email option> select Invite by individual email option and paste the emails you have.
Via this, the invite would be sent to these people but it depends on them whether they want to get connected with you or not.
I can also help with programming the entire stuff and for that matter, find relevant contacts from LinkedIn based on your criteria.
Feel free to reach out to me.

I've had to do a lot of contact list manipulation and I feel your pain.

I would go after this in two steps.
1. Upload these 200 contacts to your email client.
2. Use Linkedin add contacts tool as see in the link below.

Considerations:
1.You might need to add a special notation in your spreadsheet to make these contacts appear before all your other contacts
2. You may want to look at one of your under utilized email accounts and add the contacts there.
