Import tags from TXT or CSV

Hi all. New user here. I have done a search of the community support docs but nothing is jumping out at me as a solution.

My question is in two parts. I want to clear all existing tags (even invisible tags) and load a few common tags as below.

I'll be doing this one file at a time. No need for batching. I have around 200 songs (mp3 and WAV and some mp4 videos) where certain fields are always the same. For example;
Artist, Composer, Artist Website, Comments.

I've seen discussions about formatting with % etc, but I'll be having plain text in the text file so I'm not sure how to format the file to include the above.

I expect this would be something like; %Artist [Artist Name]%, %Composer [Composer]% etc...

What would be really handy (hint: owner of MP3TAG) is to have sample TXT files to download so we can learn from them.

Anyhow, I want to load a new un-tagged song and import these common tags into the new file. At the same time, delete every other tag that other software has embedded. In particular, there is a tag that shows up as "Where from" on some of my video files that don't show up in MP3TAG editor or any other editor. How can I delete that if it can't be found?

Thanks.

It seems to me that you don't have text-files at the moment and you want to create them just for the goal to use them as source for Mp3Tag.
How do you create these textfiles?
Mp3Tag has so many features to fill tag fields directly in different ways that are centainly easier and more comfortable to handle than first creating a textfile just for the use to fill tags with Mp3Tag.

To delete all tags with Mp3Tag can be done easy in different ways.

I strongly recommend not to delete useful content, you might regret it later.

A good way to get to know MP3tag better would be to press F1 in MP3tag to call the documentation

E.g. there is a whole section about the function that imports data from text files:
