VBA

Chad Rothschiller, a program manager on the Excel team has written a lengthy article discussing using formulas to 'clean up' data in Excel. It is very indepth and covers these topics

Andrew recently posted a piece of VBA code used to create dynamic ranges. Very useful.
Here is my original post on dynamic ranges posted back in 2004 repeated.
If you have used a range name before then you will know that it can be frustrating updating the reference of the range name if you want to add data to the range.
Here are some ways you can dynamically update the range by using the OFFSET function in the range name reference.
Assume for all these examples that column A has a mixture of text and numbers for several cells.
Click Insert - Name - Define on the menu.
In the Names in Workbook Dialog box type a range name (Eg test_range) and then try these different options.
1: Expand Down as Many Rows as There are Numeric Entries.
In the Refers to box type: =OFFSET($A$1,0,0,COUNT($A:$A),1)

Navipane contacted me to review their addin for Excel on this site.
I went to the Navipane website, downloaded, installed and used the Navipane addin for Excel. I noticed there a bunch of similar addins for other Microsoft Products, notably PowerPoint, Word and Access.

I am using Excel 2007 so this review relates to how I interacted with Navipane in that environment.

When installing you are required to have Excel closed.
The first thing I noticed after opening Excel again was that there was an addin menu called Navipane in the ribbon, and a resize able tabbed window had opened up on the right hand side of the Excel pane titled Navipane System.
The tabs listed are Home, Sheets, Favorites and History.
