In CSV files, there is rather a key for each column of data, There are a number of problem with the files I need to parse: Commas are not only for separation

During the bulk copy, I used Out-DataTable function because apparently thats the most efficient way to bulk copy (especially with our files containing 1000's of records). However, I am
