This program will take two CSV files and do a row to row compare. For this to work both CSVs need to have the same colums. Set colOmitList to FALSE if you dont want it to parse at all and remove any columns. for that to work though you have to normalize the date and number fields. NOTE: the concur data HAS pipes in it, so verify each report.
This form allows you to request diffs between any two revisions of this file. For each of the two "sides" of the diff, enter a numeric revision.
