body: <p>I have an excel sheet that has a data like this</p>
  
  <pre><code>Position        URL       Company  Location
  Developer  /xyz/123/xyz    ABC       US
  Manager    /xyz/132/asd    ASD       US
  Tester     /xyz/142/asf    ABD       US
  </code></pre>
  
  <p>I wish to capture all the url from this sheet and add "www.xyz.com/" before them and replace the old url with the new url so that the sheet becomes like this</p>
  
  <pre><code>Position        URL                  Company  Location
  Developer  www.xyz.com//xyz/123/xyz    ABC       US
  Manager    www.xyz.com//xyz/132/asd    ASD       US
  Tester     www.xyz.com//xyz/142/asf    ABD       US
  </code></pre>

  1) Open excel application scope
  2) Use read range
  3) Use for each row to fetch the url 
  4) Use assign activity to create a new variable and save the new url in it</p>
  
  <p>But i am not able to understand how to replace it</p>
