Yes i'm very sure. by calculating all cells in D will slow down the macro.
but if we can select several cell which is only "cell with data", it will
increace the speed for calculation and the macro will not stuck in
"calculating" progress for a long period.

just assume if my lookup_array and lookup_value data is 30000 rows long..
how long it will take to match if we selecting all D as a lookup_array,
compare with selecting just "cell with data".

Are you sure?

There are lots of functions in excel that limit themselves to the usedrange.

Hi all,

I have a problem to create a match function macro with the following
senario, whereby the lookup_array is currently at col D1 to D4, and the
lookup_value will be A1. The problem is my lookup_array number will change to
(D1 to D9) or (D1 to D15) or any row at row D based on new data inserted..
How to create a match macro if my lookup_array is changing everyday?


A B C D
1 123 1
2 12
3 23
4 123

thank you..
