Adapting VBA from Word to work in Excel

Hello, I am a total novice when it comes to VBA. I have been using a macro in Word created from pieces all over the internet (credit to a user named matt198992 for recursion script). The code prompts a user for folder, then runs a macro called Publish as PDF to all word files in the folders/subfolders.

I want to adapt the code in Excel, but im having trouble. Error on the line "Workbooks.Open Filename:="Path & DirN". All help would be truly appreciated. Thank you.
