Word usage count in Excel 2007

Hi

My issue is I have a bunch of sentences in different rows. I want Excel to figure out how many times a particular word is used in those sentences.This is how it is

Thanks mate we forgot

How many versions of the Memory

Depending on how you look at it

------------

This is how I approached it.I split the text into different columns using the built-in Text to Columns functionality. This is how it looks

Now I have two choices.

First alternative:

I can move all the words to one column and build a pivot table.However I will need to move manually since I do not want to use macros.There is a chance I might deal with 50 columns. I might also run into Excel limitation of 65,000 rows. Is there a way to do this in a simple manner? 

Second alternative: 

Build a pivot table. However a pivot table creates a column for each column in the source data. Is there a way I can force the pivot table to create only one column from multiple source columns?

My limitations:

Excel 2007

End users not familiar with Macros

Please help! Any other alternatives are also appreciated.

Thanks
