ASR Studio - Excel Spreadsheets loading ?

Anyone using Documentum and loading Excel Spreadsheets ? and How ?

Customer has daily request for loads of a CSV file actually ( No header information just line data )

I can easily convert it to Excel, but How is this then loaded.

I can't see anything for convert Text to Excel or anything like that.

New to Documentum .. So if anyone can just point me in the right direction I can then learn it from there,

Thanks
