I get the error:

Looks like your CSV file is not being parsed properly. Please see read article: How to fix CSV problems using Excel.

I tried to follow the directions.  Please see my original and modified files.

Original:

"-$67.17","","-$67.17","Utilities","PMT","","JCP&L","08/22/2018","Pending","","N60YN-KCF6K","no",
