title: How to replace the single quote ( ' ) into double quotes ( " ) in Robot Framework?
body: <p>I have a List, items are created by append by a Loop. I want to use this list as a json. The problem is that the items of that list use the single quote so it can't be the json.</p>
  
  <pre><code>Get Order Items
      [Tags]    Get Order Items
      Set Headers    ${HEADER CUSTOMER}
      GET            ${ORDER GET BY CODE ENDPOINT}/${ORDER CODE}
      Integer        response status    200
      ${NUMBER OF ITEMS}    Output     $.number_of_items
      ${NUMBER OF ITEMS}    Evaluate  ${NUMBER OF ITEMS} + 1
      ${ORDER ITEMS}     Create List    
      :FOR    ${i}    IN RANGE  1  ${NUMBER OF ITEMS}
      \    Append To List    ${ORDER ITEMS}    ${ORDER CODE}${i}  
      Set Global Variable    ${ORDER ITEMS}
  </code></pre>
  
  <p>Actual result: ['N19072596HB1', 'N19072596HB2', 'N19072596HB3', 'N19072596HB4', 'N19072596HB5']</p>
  
  <p>Expected result: ["N19072596HB1", "N19072596HB2", "N19072596HB3", "N19072596HB4", "N19072596HB5"]</p>
