At one time, there was a custom header in a spreadsheet with the word "Scarborough" in it. I edited the header and removed the word. I then used this file as a template file, and every spreadsheet that I create from this template continues to be found by Windows Explorer when I search for this word but nothing I am able to do in Excel searching seems to be able to find out where this word is actually stored.

Are there any additional tools that I can use to locate where in my spreadsheet this word might exist?
