Split cell data into rows

Hello,

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

Example:







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

Thank you!

    Puh,
    i think not with TurboPrep: Are normal processes also fine?

    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">
      <context>
        <input/>
        <output/>
        <macros/>
      </context>
      <operator activated="true" class="process" compatibility="9.4.000-BETA" expanded="true" name="Process">

          <connect from_op="Generate ID" from_port="example set output" to_op="Execute Python" to_port="input 1"/>

        </process>
      </operator>
    </process>
    

    Hope this helps,
