I have zero experience in Word VBA. I am looking for a way to change the header in one document and update multiple documents in a specified folder.

We have specification documents that need to have their headers updated quite regularly. I'd like to be able to use a Word document as the template where any changes that need to take place will occur in the document. I would then like to use that document to change multiple documents automatically. These other documents would be located in a folder. Ideally, the process flow would be like this:

Open "template.docx"
Open Header/add date "March 1, 2018"
Close Header
Save document
Run macro - select folder location of all documents that need the header changed.

Currently we copy/paste the updated header into each document separately which involves opening document/open header/paste/close header/save/close document repeat 100+ times. This process takes place for one project, extrapolate to the 100s of projects my company produces...you get the picture.

I've stumbled upon this thread and code but have not been able to understand it:

It appears as if this code should work but I must be missing something as to I don't understand how to make it grab the folder location and institute the changes made to my template document.

Version: Word 2013

Thank you for your time,
