Rarely used but much loved the pipe key, I use it in Excel to reveal formulas with CTRL + `

press again to reveal data.

Grr how do you show Percentage Changes

This is not an obvious one but I was aksed how can I show a percentage CHANGE between two values,
eg.
Sales in 2009 were 75K and by 2010 had risen to 125K what is the % change ?

The Formula you can use is as below:

Thus returning a value of 67%

nice one !!!

Another IF ISERROR example

IF ISERROR and VLOOKUPs

=IF(ISERROR(VLOOKUP(E6,CostTable,2,FALSE)*E6),0,VLOOKUP(E6,CostTable,2,FALSE)*E6)

use the above to solve your Excel 2003 Vlookup error requirements, this enables SUM calcs to still give you an answer  and replaces error cells with zeros.

IF ISERROR VLOOKUP

Another problem was how to use an IF ISERROR combo in Excel 2003 as this was much simplified
in Excel 2007/10 with the IFERROR Function.

see the screen shot above for a solution.
