I've been trying for a few weeks to gather email attachments into one single file. I receive hundreds of emails with excel attachments in the same format and I need a way to automatically compile all of those attachments into one single file. For example, if I get the two tables on the left in two different emails, how do I get them together to look like the table on the right?

I tried following this video tutorial, but there's an issue with running scripts that I can't get around so I'm trying to find a method that works without using them. Any help or ideas would be appreciated!
