InDesign Metadata script for document title and author

[Supa_Pea]

Hi, I need to add metadata on 100+ documents for three different products. Is it a script that I can run on them instead of manually adding meta doc title and author 1 by 1?

For exmaple, the file name is TEST_document_form.pdf, title will need to be TEST document form, and author will be TEST. Basically, same file name for title but without the underscores and '.pdf.' (See screenshot). I have three product names for 'author' (i.e. TEST), I will need to be to able amend this in the script.

These documents will be updated from time to time, so I'm looking for an efficient way to maintain.

I have seen people post scripts in replies, but I'm not sure how to save it as a script file? i.e copy the code from broswer, then where do I paste to re-save and what format? Apologises if this is silly but I'm new to scripts and couldn't quite understand it from other posts.

Many thanks for any help in advance.
