Importing Logins to Vault

Is it possible to import logins from a CSV file created in Excel, but not from a previous password manager?

I have failed on two  attempts because the software appears to demand a CSV file from a previous password manager.  I am creating my first-ever vault  and would much rather import my est. 75 different logins from the Excel-created CSV that I used to use in place of a secure vault, than have to type or copy/paste 75 sets of Name/URL/Username/Password.
