Finding Min/Max based on multiple criteria (NOT USING ARRAY)

[bmd205]

Hello-

I've been searching forums all morning trying to find a way to find a way to get the minimum value using two criteria. Here's a sample of what my data looks like, and ideally what I'd like to see as a result.

Case #	Size	Date
1	Small	201501
1	Small	201512
1	Large	201503
1	Large	201508
1	Large	201511
2	Large	201507
2	Large	201511
2	Small	201503
2	Small	201508
2	Small	201501

<tbody>
</tbody>

Ideal output:

Case #	Size	Min	Max
1	Small	201501	201512
1	Large	201503	201511
2	Small	201501	201508
2	Large	201507	201511

<tbody>
</tbody>

I am familiar with Arrays, and I have done a Max(if( nested statement to get the results I need, but I'm also building a macro that will loop through my output (could be 100k+ rows) and the Array Formula just doesn't seem efficient.

Is there a way to write some VBA code to loop through and find the min based on two criteria (Case # and Size)??
