Split cell data into rows

Is there a way to split data in a cell to rows, instead columns?


What I really need now is the results one below the other, instead of columns....

Thank you!

    Hi @thiago_caixeta,

    I propose an alternative method using a Python script  (Pandas library) to perform what you want to do : 

    To execute this process, you will need : 
     - to install Python on your computer.
     - to install the Python Scripting extension from the Marketplace.

    The process : 

    <?xml version="1.0" encoding="UTF-8"?><process version="9.4.000-BETA">
      <operator activated="true" class="process" compatibility="9.4.000-BETA" expanded="true" name="Process">

          <portSpacing port="sink_result 1" spacing="0"/>
          <portSpacing port="sink_result 2" spacing="0"/>

    Hope this helps,
