This 'housekeeping' looks like a lot of work and it's probably rather slow: but this is 'last mile' code to write to the sheet, and everything is faster than writing to the worksheet. However, there's some housekeeping to do, as you must specify the size of the target range correctly. This is much faster than writing the data into the sheet one cell at a time in loops for the rows and columns. Here's A generic VBA Array To Range function that writes an array to the sheet in a single 'hit' to the sheet. Since I don't know what the dimensions are from the get go I can't declare it like Dim s2Array(1, 1) because then I'll get an out-of-bounds exception. The same error occurs if I change it to Dim s2Array(1 To totalRow, 1 To totalCol). When I attempt to run this I get a compile-time error at the Dim s2Array(totalRow, totalCol) saying that a constant expression is required.

The arrays are populated by numbers in Excel sheets (one set of numbers is on Sheet1 and another set is on Sheet2, both sets have the same number of rows and columns). I'm trying to create a program that will utilize two 2-Dimensional arrays and then perform simple operations on those arrays (such as finding difference or percent).

I was trying to find out how to declare a 2-Dimensional array but all of the examples I have found so far are declared with set integers.
