title: Excel search for cell references in formulas
body: <p>I inherited a big model and have been trying to reverse engineer some of the formulas. There are a lot of fields. I am not sure if everyone of them is necessary. </p>
  
  <p>Is it possible to search an Excel document (with 5 worksheets) to find if say, AZ12 is used in any formula? Or $AZ12 or $AZ$12? </p>
