VBA-style range selection in Excel - vba

Question

In a spreadsheet formula, (namely SumIfs) I would like to be able to select a column range using its delimiters instead of a A1:A3456 style, like I would do in VBA [Range("A1:A3456")~Range(Cells(1,1),Cells(3456,1))].
If this is not possible, is there any workaround to use the result of a 'Match' function to get the column number where I want to apply certain criteria?
My function would look like
=Sumifs(A2:A10;*{range(cells(1,match(Z5;A1:T1)), cell(10,match(Z5;A1:T1))}*,"="&1)
...if only I could add vba formulas inside the spreadsheet.

Answer 1

You can use a combination of Address and Indirect, like this:
=SUM(INDIRECT(ADDRESS(1,1) & ":" & ADDRESS(3456,1)))
which is equivalent to =SUM(A1:A3456)
ADRESS transforms from style Cells(i,j) to style A1.
INDIRECT serves to interpret the resulting string as a range address.
SUM here is an example of usage.
Well It's a bit ugly, but if you want to do that occasionally and don't want to switch completely to RC-style, it's probably the easiest way.

Answer 2

Use Offset, which is much richer as a worksheet function than it is in VBA.
Syntax
OFFSET(reference, rows, cols, [height], [width])
The OFFSET function syntax has the following arguments:
Reference Required. The reference from which you want to base the
offset. Reference must refer to a cell or range of adjacent cells;
otherwise, OFFSET returns the #VALUE! error value.
Rows Required. The number of rows, up or down, that you want the
upper-left cell to refer to. Using 5 as the rows argument specifies
that the upper-left cell in the reference is five rows below
reference. Rows can be positive (which means below the starting
reference) or negative (which means above the starting reference).
Cols Required. The number of columns, to the left or right, that
you want the upper-left cell of the result to refer to. Using 5 as the
cols argument specifies that the upper-left cell in the reference is
five columns to the right of reference. Cols can be positive (which
means to the right of the starting reference) or negative (which means
to the left of the starting reference).
Height Optional. The height, in number of rows, that you want the
returned reference to be. Height must be a positive number.
Width Optional. The width, in number of columns, that you want the
returned reference to be. Width must be a positive number.
