How To Use CSV?

What is the procedure for bulk uploading data in a CSV file?

I’m not using a spreadsheet, but am instead attempting to regex a big pile of data in text files in to the correct format for uploading in a CSV.

When I download the CSV file for some data currently in my database I get this:

title,id
Title,”Record ID”
“Our Relationship With Knowledge”,3
“Focusing On The Bottom Line”,4
“A Benefit Of The Coronavirus”,5

I take this to be an example of how an imported file should be formatted. But where is the rest of the data for these records, as example, the URLs associated with these article names?

Can CSVs be used for bulk uploading large amounts of data? If yes, what is the appropriate format for that file?

Thanks!
