Hey folks,
This thread ended up being useful to me so I figured I would bump it up and contribute. I created a VBA script in Excel to automate the task of editing the SE XML export files to conform to ME standards. It is by no means refined, but I have tested it and used it successfully on a large amount of conversions. If anyone wants to take it and refine it (better interface, batch support, etc.) by all means please do and repost! I am lazy and just needed to mock up something quick after creating a large project in SE only to learn it should've been done in ME.
All testing was done in FTView 8.1.
You will have to change the file extension from .xls to .xlsm.
You can access to the code and see what the macro is doing by pressing Alt+F11 or going through the developer ribbon in Excel.
There is no malicious code in this file, but be wary of files with macros as they can be dangerous; the functionality will likely be disabled when you first open it.
There may also be additional XML tags or attributes that can be found in SE projects that need to be removed for ME imports. If you find some and aren't confident modifying the code yourself to account for it, go ahead and post about your experience and I will revise the file and re-upload!
Thanks!
