title: Changing background colour of a cell in excel
body: <p>I need to change the background colour of every cell with text "Change". Any ideas how I can achieve that using OpenXML? I have achieved only for changing for one specific cell(columnName + rowIndex), but not for all cells which value is "Change".</p>
  
  <p>Is it doable with OpenXML or I need to use a different approach?</p>
