Understanding offset function

Dear experts,

I have the below formulae,

=IF(COUNT(MATCH(C4,'data elements'!B3:K3,0)*MATCH(E3,'data elements'!A4:A9,0)),INDEX(OFFSET('data elements'!B4:K9,MATCH(B2,'data elements'!A2:A22,0)-1,0),MATCH(E3,'data elements'!A4:A9,0),MATCH(C4,'data elements'!B3:K3,0)),0)

What i want to understand is how does the function 'offset' and ')-1' work, what is the logic of this.

'INDEX(OFFSET('data elements'!B4:K9,MATCH(B2,'data elements'!A2:A22,0)-1,0),'

Thank you

The syntax for the Offset function is:

    Offset( range, rows, columns, height, width )

range is the starting range from which the offset will be applied.

rows is the number of rows to apply as the offset to the range. This can be a positive or negative number.

columns is the number of columns to apply as the offset to the range. This can be a positive or negative number.

height is the number of rows that you want the returned range to be.

width is the number of columns that you want the returned range to be.

so to your question -1 is the height relatively the range parameter.
so if range is C4, -1 as height parameter yields C3

In this version of OFFSET

OFFSET('data elements'!B4:K9,MATCH(B2,'data elements'!A2:A22,0)-1,0)

only three arguments are used, range, rows and columns. Height and width are omitted which means that the height and width will remain as per the range.

Column argument is zero so the range will not only remain the same size as range but it will only move vertically. The amount it moves is determined by MATCH function, so if B2 matches the first cell in the MATCH range, i.e. data elements'!A2 then MATCH returns 1 and with -1 that means that the original range is supplied by the OFFSET function.....but if B2 matches with, say, data elements'!A12 then MATCH returns 11 and with -1 that means that the range is just moved down 10 rows and becomes

'data elements'!B14:K19
