I am using a mac so I opened the .csv with text edit and it says "address, private_key"
The .csv file is just a plain text file that you can open with any plain text editor or even a word processor if you have to.
The address, private key pairs are start on the second line. For example here's a test wallet:
address,private_key

So you can get back your coins very easily.
- Run electrum
- Go to file menu > new/restore > navigate to a convenient location on your file system and enter a filename for your new wallet > click save
- Then proceed to create a new wallet as normal.
- Once you've created a new wallet import your private keys by Wallet menu> private keys >import. Click yes to make the warning go away and then enter each key on one line like so:
5KGqiVAQStjj2zf6Q3a1SAYhP4UCw2Fh9PweN2bUTPDSatyme5S
5Jverug9poXUgi73A4n3ZRRLRCfqkNAYs5wZCLv5meNxh8qjr91
- Click on import and you are done!
