OFFSET

Returns a modified reference, given a reference, an offset, and a desired size.

Syntax:

OFFSET(reference, row_offset, col_offset, new_height, new_width)

reference is the given reference, which may be a range.

row_offset and col_offset are the number of rows / columns to move reference down / right by. Negative numbers are allowed.

new_height and new_width set the height and width of the new reference, by adjusting the bottom right corner. These are optional parameters.

Example:

OFFSET(A1, 1, 2)

in a cell, returns the contents of cell C2. The new_height and new_width parameters have been omitted.

OFFSET(B3, -2, 0, 1, 1)

in a cell, returns the contents of cell B1. A negative offset is allowed.

SUM(OFFSET(A1, 2, 2, 2, 3))

in a cell, returns the sum of the contents of cells C3:E4. 2 rows and 2 columns are added to A1 to offset it to C3, and then the new size extends the range to E4.

SUM(OFFSET(C1:G1, 0, 0, 1, 3))

in a cell, returns the sum of the contents of cells C1:E1.
