.csv format issue

In the past, I have downloaded a .csv file, comma separated, which listed the contents in a column style/format.

The most recent file I downloaded [.csv file, comma separated] lists the same information in a linear format with vertical lines separating what used to be in individual columns.

I have not changed my Excel settings.

Is there anything I am able to do to convert this file back to the original format? Or is this an issue with the file format at the originating point?

(the attached is a small piece of the actual & very large file; both original and current)

Thank you for any help.

no, it was all the data; however, the source corrected the issue on their end - I wasn't sure how long it would be and needed to correct the file quickly.

Thank you for the help (and I will tag in the future).
