## Explaining OFFSET function

In this post I am going to provide some basic examples to demonstrate how the OFFSET function works. I also show practical examples where I use the OFFSET function. To be honest, in most cases I prefer using the INDEX function. The offset functions is volatile and extensive use in a workbook may slow down calculations noticeably.

### OFFSET(reference,rows,columns,[height],[width])

Returns a reference to a range that is a given number of rows and columns from a given reference. Height and width arguments are optional.

### Example 1 - Basic demonstration

This example uses only the two first arguments in the OFFSET function, row and column.

B3 is the start cell. 1 row below B3 is B4. 1 column to the right of B4 is C4.

The OFFSET function returns a cell reference to cell C4. Cell C4 contains number 22.

### Example 2 - Row function and offset function

This example shows that the offset function returns a cell reference.

ROW(reference) returns the row number of a reference. Combining the ROW and OFFSET functions demonstrates that the OFFSET function returns a cell reference.

### Example 3 - Explaining row and height arguments. OFFSET function returns a reference to a cell range

The Offset function can also return a reference to a cell range. For this to work you need to enter the formula as an array formula.

**Array formula in cell range B9:B10:**

=OFFSET(B3,1,1,2,1)

The optional arguments height and width are used in this exampe. The height is 2 and the width is 1, that is 2 cells high and 1 cell wide.

The array formula returns a reference to a cell range with the same width and height as the two last arguments.

### How to enter an array formula

- Select cell range B9:B10
- Click in formula bar

- Paste array formula to formula bar
- Press and hold CTRL + SHIFT
- Press Enter
- Release all keys

### Example 4 - SUBTOTAL and OFFSET functions

This example shows how to determine if a row in an excel defined table is hidden or visible.

**Array formula in cell range C7:C9:**

=SUBTOTAL(3,OFFSET(B3,MATCH(ROW(Table1[Name]),ROW(Table1[Name]))-1,0,1))

The technique is described here by David Hager and John Walkenbach: Excel Experts E-letter

I have written a couple of posts and developed this technique one step further:

- Count unique distinct values in a filtered table
- Extract unique distinct values from a filtered table (udf and array formula)
- Excel table: Filter unique distinct values (array formula)
- Vlookup visible data in a table and return multiple values in excel

### Example 5 - Named ranges and the OFFSET function

You can use the OFFSET function to create a dynamic named range. First I want to explain what named ranges is and how you can use them.

So what is a named range? You can select a cell or a range and name it. When you enter the arguments in a function you can use the name instead of the corresponding cell reference. Why? This makes it easier to read and understand a function. Compare this function =Sum(C1:C11) to this =Sum(Sales2011). The latter is easier to understand.

What is dynamic named range? It is a cell range that expands automatically when new values are added.

**Named range formula:**

=OFFSET(Sheet5!$B$4, 0,0,COUNTA(Sheet5!$B$4:$B$100))

COUNTA counts the number of cells in a range that are not empty. COUNTA(Sheet5!$B$4:$B$100) returns 3.

=OFFSET(Sheet5!$B$4, 0,0,COUNTA(Sheet5!$B$4:$B$100))

becomes

=OFFSET(Sheet5!$B$4, 0,0,3)

and returns a reference to cell range B4:B6.
