I wouldn't quite call your source a csv file!!! This is not formatted in a consumable manner.

Whomsoever it is that generates this file should provide an actual data file. SSIS can't do anything with this.

You are better off using vba to parse the Excel into an actual csv but methinks this is not the only manner in which this file will show up so I am guessing there is no repeatable process you can write until they standardize the source data into an actual Data File.

Good luck!
