title: How do I get an full Excel range address using row and column numbers in office.js Excel Addin?
body: <p>Next example gives me <strong>"Sheet1!C3"</strong>:</p>
  
  <pre><code>Excel.run(function (ctx) { 
      var sheetName = "Sheet1";
      var worksheet = ctx.workbook.worksheets.getItem(sheetName);
      var cell = worksheet.getCell(3,3);
      cell.load('address');
      return ctx.sync().then(function() {
          console.log(cell.address);
      });
  }).catch(function(error) {
          console.log("Error: " + error);
          if (error instanceof OfficeExtension.Error) {
              console.log("Debug info: " + JSON.stringify(error.debugInfo));
          }
  });
  </code></pre>
  
  <p><strong>It is possible to get full address like "Sheet1!C3:E4" using start and end row and column numbers ?</strong></p>
