    Thumbs up Variable Range definition to conserve memory.

    I am trying to cut down on the memory my Excel program uses.

    One problem is the use of whole column references , i need to use A$1:A$2000 rather than A:A UNLESS I have more than 2000 rows.

    In particular, I use a lot of Sumifs statements, particularly to summarise pivot tables. The number of rows displayed by the pivot table can vary wildly. Is there a way of setting the last row in a target range as a variable? It is relatively easy to calculate the last cell

    Lastrow=Match("Grand Total",A:A,0)

    Can I define ranges by reference to this variable? ie (A$1:A$(LASTROW)) and if so how? I could use VBA,but is there another way?

    I think dynamic ranges is what you need. Check this https://www.excel-easy.com/examples/...med-range.html

    maybe try using INDIRECT? You create a text inside of it and then it executes it as if it was code

    e.g. INDIRECT("A$1:A$" & {formula or method of returning the number of the row you want})

    Then you can put the whole INDIRECT() formula inside of your match function where the range would be

    Thank you Both, I think KOKOSEK has it. Will experiment with this over the next couple of jobs.

    Can I define ranges by reference to this variable? ie (A$1:A$(LASTROW)) and if so how?
    Yes. Personally I prefer this method learned from Guru Tony Valko.

    Use approximate MATCH(25^25,$A:$A) for numbers and MATCH("zzzzz",$A:$A) for text to identify the last row.

    Then in Name Manger set the dynamic named ranges as =$A1:INDEX($A:$A,MATCH(25^25,$A:$A)) for numbers and =$A2:INDEX($A:$A,MATCH("zzzzz",$A:$A)) for text.
