Macro optimization for speed

[mlegge04]

Hi below I have a working but non-elegant macro by any means. I have a feeling the speed issues are related to having the ranges set all the way to the end of the workbook as opposed to the last row of data. Any improvements would be greatly appreciated. I have highlighted what I believe to be problematic areas.

Thanks

I use:

to determine the last row of data. Use a column that will always have entries in every row, for example a key/ID field.

Then replace all references to 1048575 with lLR.

You're probably right. Did you try to modify them:

ActiveSheet.Range("$A$2:$BM$" & Lastrow).RemoveDuplicates Columns:=3, Header:= _
xlYes

ActiveCell.FormulaR1C1 = "=COUNTIF(R[1]C:R[" & Lastrow & "]C,"">0"")"

ActiveSheet.Range("$AK$1:$AK$" & Lastrow).AutoFilter Field:=1, Criteria1:= _
"<>*fill*", Operator:=xlAnd

And so on.

Hi John,

I applied your method it did work, shaved a little bit off the run-time not as much as i had been hoping for though unfortunately.

Thank you though
Much appreciated!

Try changing the range for RemoveDuplicates.

Also, get rid of Select.

You're welcome. Hope you take some of the other advice as well.
