Create program to process excel/xml files from one format to another

I have source files of Excel file that inclused product description + Excel file of category numbers to make a look up at or XML file that already includes both data that will need to be transfered to Excel file. ## Deliverables A better option would be to be able to connect to the DB and search for the correct category in the DB - we have a category table, another simpler option would be to just enter the categoryID's that are set in the XML, or loox for them in the Excel if you prefer to work with excel files Detailed Convertion Explanation will be given later. Attached are example files for source and destination.
