title: Declaring variables in Excel Cells
body: <p>Is it possible to declare variables in Excel cells and use them as parameters for formulas in other cells? </p>
  
  <p>For example I would declare <code>var1=10</code> in one of the cells.
  In another cell I would use <code>var1</code> for calculation like: <code>=var1*20</code>.</p>
