It simply reformats the data from multiple lines per part number, and spits it out to a new worksheet with part number on one line, all of its suppliers in adjacent columns.

It creates a dictionary object and adds each Part Code to that dictionary. As it processes each Part it checks if it is in the dictionary, if not, it adds it and its supplier, if it does it just appends the supplier to that dictionary part item.

Then it dumps the dictionary items into an array, loops the array and splits each element into its component parts and loops through those dropping them all into a single row.

The last loop can be done in a single statement, without the loop.
