How do you envisage a user initiating this job? Is it their own spreadsheet or one held centrally?
I'm assuming that your question is not just: "Can SSIS import data from Excel spreadsheets?" (to which the answer is 'yes', of course)
... and please clarify what you mean by "application."
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.
