We have 2 ways of getting your songs online: One way is to just copy and paste from an Excel file. The other way is to save your Excel file as a csv file and click the import button in the Admin area.
With just the very basics of Excel you can get your list of songs into Excel from any format. Once your list is in Excel it's just a matter of doing the things mentioned above in the Admin area. If you're confused about Excel or formats we can help you with this matter.
Also there are free versions of Excel.
