File Format for 1099 beginning balance import

SOLVED

Does anyone know what the file format needs to be for the 1099 Beginning balance import function? i tried Excel and it kicked out immediately, i tried CSV and it's not reading the comma delineation. I did some digging and it sounds like it's expecting a flat csv file, but i can't find any details on what the format should be in the knowledgebase anywhere.

Our vendor numbers don't fill the amount of characters it seems to be looking for per the error log (looks like 12 characters?) should i fill in the blanks with zeros? I'm afraid to experiment because i've read you can't reverse the data once it's been loaded in.
