ahhh. I think the "omit spaces" is why it wasn't working. Thank you. Maybe an ignorant question, but I have what seems like well over 100 keys. Is there a quicker way to get these into electrum?
You should be able to copy the entire block of keys. Then just remove all of the "PrivBase58:" using a find and replace. You should just have the private keys left and then you can copy and paste that whole thing into the Electrum sweep box since that can take multiple keys, one on each line.
