Why did you add the for loop? That doesn't make any sense to me. Get rid of that and you will have every data point acquired. Leave it there, and select Enable Indexing out of the for loop and you can wire the 2D array out of there into the 2D array input of Write to Spreadsheet File. The problem with the for loop is that no matter what, it is only the result of the last comparison that is passed to the stop condition.
