I'm making a script that will write a two-dimensional array to an Excel spreadsheet. The script is meant to be called from within other scripts. An outer loop runs once for every row in the array ...

Excel has SumIf and CountIf, but no AverageIf. However, with a little array magic, you can get Excel to average values, conditionally.

Excel has announced a new array-based function called SORT, which can be used to sort data in one or more columns without involving a manual sort process or a complicated macro process.
