Well, what you are describing is "How to save data from separate tests and maintain some sort of organization". Excel, with each Test being a WorkSheet, and multiple repetitions being an added Row, is certainly one way to do this. Another way would be to use a DataBase (but this might be OverKill). Another way to structure this is to have a File for each Test ("Test 1 Results.txt"), open the File for the respective Test, and write the Test Results at the end of the File (it's pretty simple to append text to a text file). You can even do this with a .csv file, if you choose.
Having said all that, depending on what you want to do with all these data may make a convincing argument for Excel, where all the data from all the tests are in a single file, and a non-LabVIEW user who knows Excel can "play" with the data, make graphs, do statistics, etc. Depending on how much data, how many Tests/Sheets/Files you have, how often you add to the data, you may decide it is cost-effective to purchase a Solution (like the RGT, or one of the other Excel-compatible methods), or else (if you only need to do this once), you could open the 5 (I'm assuming) .csv files in Excel, then copy them (in Excel) to the Excel WorkBook that has one WorkSheet per Test. A little manual labor, but if you don't do this often, pretty cost-effective.
