Importing data from another spreadsheet to a different format
 

Hello. I'm trying to take a list of items in a simple array and import them
into a second excel file. This second file is formatted much differently,
and is incredibly large.

I was using a simple copy and paste for a while until I realized that this
process would likely take me a month or two to get through the whole database.

Would anybody out there be willing to advise me to a different course of
action, please and thank you?
