Where can a complete noob/non-technical person learn to setup an AI that can manipulate local files for things like batch renaming based on a .csv column etc?

I've looked in the Tutorial/Guide flaired posts but everything is still way over my head.

I just want to tell a local AI - hey, all these files in this folder have numbers for names, but those numbers correspond with data in this spreadsheet... I want you to rename the files referring to this spreadsheet, renaming the filenames/numbers that are matched in column 3, replacing their filenames with what is in column 1 for that row.

So far, I've installed GPT4All but every model is telling me it doesn't have access to my local files.
