I am using the following as an array lookup and it works but the speed is killing me.


I only need columns A-J and Rows 5 - 2000 with row 5 being the field name.  How can I adjust this lookup to get me more speed?

Clearly you can limit the format to those rows,....perhaps also a different syntax, try


confirmed with CTRL+SHIFT+ENTER

How many of these do you have?

I got the syntax copied and it works but if I copy it down I get the same value in each row.

It's working OK for me......!

Sorry if you know.....how are you doing CTRL+SHIFT+ENTER? You need to click in the cell with the formula and then press F2 to select - then hold down CTRL and SHIFT while pressing enter.....

Is the A31 fixed for all the formulas with C39 changing as you copy down - what about the lookup ranges does col A + Col D become B and E then C and F etc.?
