Excel Integration and data cleansing required

Hi all

I have two data sources - an excel spreadsheet and one access database of Customer details, (quite small in size) and I have to use SQL Server 2005 to Integrate the data and cleanse the data so that I could (in theory) import it into a CRM system (though I won't actually be importing it) as this is for coursework only.

Is there a simple steps to do this is SQL server and guides that I can follow that are relevent? As there are lots of tutorials and I haven't a clue where to start.

many thanks
