title: Excel cell color based formating
body: <p>I am not sure if this is even possible. I have the worksheet (sheet1) as shown below.
  Green - Indicates user should have access
  Red - Indicates user should not have access</p>
  
  <p>Based on the color coding for Member A, Member B in row 1 &amp; 2. When Member A or B is selected in A4 to A100, the cells ("Field 1", "Field 2"....) should be enabled disabled based on the color coding. 
  Please let me know if this is possible. </p>
