Specifying range from A2 till infinity (NO VBA)

If you want to refer to a range starting from A2 until max row (1048576 or 65536 for Excel prior to 2007), you can use this volatile formula... =OFFSET(A2,0,0,(COUNTBLANK(A:A)+COUNTA(A:A)-1),1) . Use formula as a defined range name or inside other formula which takes range as an argument (for eq SUM)...

Depending on what's in A1 and what formula you're putting the reference into, you could simply use A:A. For example, if you wanted to sum all of the values in column A, but A1 contained a column title rather than a number, you could still write =SUM(A:A) and the title in A1 would just be ignored.

A2:A works in many formulas hope that helps
