Possibly one of Excels most underutilized aspects is its ability to create dynamic named ranges that will expand and contract according to the data in them. Below are 7 different types of these ranges.

These Add-ins are designed to increase your Excel productivity, eliminate errors and do what can only be done via VBA code. The **OzGrid Excel Plus **includes a ** "Dynamic Named Range"** creator that can create all the different types.

**Named Range Manager **Excel Add-in that does dynamic named ranges and so much more!

**Dynamic Named Ranges Examples**

For **ALL** examples you need to:

- Fill
**Column A**with a mix of text and numeric entries. - Go to:
**Insert>Name>Define**and in the**Names in workbook**box type any one word name (I will use**MyRange**) the only part that will change is the formula we place in thebox.*Refers to*

- 1:Expand Down as Many Rows as There are Numeric Entries.

In thebox type:*Refers to***=OFFSET($A$1,0,0,COUNT($A:$A),1)** - 2:Expand Down as Many Rows as There are Numeric and Text Entries.

In thebox type:*Refers to***=OFFSET($A$1,0,0,COUNTA($A:$A),1)** - 3:Expand Down to The Last Numeric Entry

In thebox type:*Refers to***=OFFSET($A$1,0,0,MATCH(1E+306,$A:$A,1),1)**

If you expect a number larger than**1E+306**(a one with 306 zeros) then change this to a larger number. - 4:Expand Down to The Last Text Entry

In thebox type:*Refers to***=OFFSET($A$1,0,0,MATCH("*",$A:$A,-1),1)** - 5:Expand Down Based on Another Cell Value

Put the number 10 in cell B1 first then:

In thebox type:*Refers to***=OFFSET($A$1,0,0,$B$1,1)**

Now change the number in cell**B1**and the range will change accordingly. - 6:Expand Down One Row Each Month

In thebox type:*Refers to***=OFFSET($A$1,0,0,MONTH(TODAY()),1)** - 7:Expand Down One Row Each Week

In thebox type:*Refers to***=OFFSET($A$1,0,0,WEEKNUM(TODAY()),1)**

Requires the "Analysis Toolpak" to be installed.**Tools>Add-ins-Analysis Toolpak**

The good thing about number **3,4,5,6** and **7** is that they will include blank cells.

You can also change the **Columns** the dynamic range will span by simply changing the last **Argument** of the **OFFSET** function to a higher number than 1.

You could even expand across your **Columns** dynamically by placing another**COUNT** or **COUNTA** formula as the last argument, instead of 1. See below:

In the **Refers to** box type: **=OFFSET($A$1,0,0,COUNTA($A:$A),COUNTA($1:$1))**

This dynamic range will now also expand across **Columns** in **Row 1**. So if you add another **Column** to your **Table** the dynamic range will automatically incorporate it.

To try and give you a better understanding of the **OFFSET** formula, read the text below taken from the **Excel help file**.**OFFSET(reference,rows, cols,height,width)****Reference** : is the reference from which you want to base the offset. Reference must be a reference to a cell or range of adjacent cells; otherwise, OFFSET returns the #VALUE! error value.**Rows** : is 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** : is 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).

If rows and cols offset reference over the edge of the worksheet, OFFSET returns the #REF! error value.**Height** : is the height, in number of rows, that you want the returned reference to be. Height must be a positive number.**Width** : is the width, in number of columns, that you want the returned reference to be. Width must be a positive number.

If height or width is omitted, it is assumed to be the same height or width as reference.
