  Hi @marcel_drewes,
  
  I'm not sure to understand  : 
  ">60%" of what ?
  Can you describe your dataset and explain (by giving an example) what you want to obtain ?
  Depending on what you want to do, maybe Generate Attribute and/or Aggregate operator(s) can be helpful....
  
  Regards,

  Hi,
  
  I am sorry, I am new here. First let me describe my current excel file, it looks like the following:
  
  Customer:__Return rate:__
  A_________64%________
  B_________19%________
  C_________33%________
  D_________82%________
  ...
  
  and I want to convert it into this:
  
  Customer:__Return rate:__(Return-Class:)
  A_________64%________(High Returns)
  B_________19%________(Low Returns)
  C_________33%________(Mid Returns)
  D_________82%________(High Returns)
  ...
  
  so:
  >60% = high
  <20% = low
  21-59% = mid
  
  Thanks for help!

  Hi @marcel_drewes,
  
  Here an other example of process which performs what you want to do : 
  

  <?xml version="1.0" encoding="UTF-8"?><process version="9.1.000-BETA2">
    <context>
      <input/>
      <output/>
      <macros/>
    </context>
    <operator activated="true" class="process" compatibility="9.1.000-BETA2" expanded="true" name="Process">
      <parameter key="logverbosity" value="init"/>
      <parameter key="random_seed" value="2001"/>
      <parameter key="send_mail" value="never"/>
      <parameter key="notification_email" value=""/>
      <parameter key="process_duration_for_mail" value="30"/>
      <parameter key="encoding" value="SYSTEM"/>
      <process expanded="true">
        <operator activated="true" class="operator_toolbox:create_exampleset" compatibility="1.7.000" expanded="true" height="68" name="Create ExampleSet" width="90" x="45" y="85">
          <parameter key="generator_type" value="comma_separated_text"/>
          <parameter key="number_of_examples" value="100"/>
          <parameter key="use_stepsize" value="false"/>
          <list key="function_descriptions"/>
          <parameter key="add_id_attribute" value="false"/>
          <list key="numeric_series_configuration"/>
          <list key="date_series_configuration"/>
          <list key="date_series_configuration (interval)"/>
          <parameter key="date_format" value="yyyy-MM-dd HH:mm:ss"/>
          <parameter key="input_csv_text" value="Customer,Return_rate&#10;A,64%&#10;B,19%&#10;C,33%&#10;D,82%"/>
          <parameter key="column_separator" value=","/>
          <parameter key="parse_all_as_nominal" value="false"/>
          <parameter key="decimal_point_character" value="."/>
          <parameter key="trim_attribute_names" value="true"/>
        </operator>
        <operator activated="true" class="generate_attributes" compatibility="9.1.000-BETA2" expanded="true" height="82" name="Generate Attributes" width="90" x="313" y="85">
          <list key="function_descriptions">
            <parameter key="Return-class" value="if(parse(replace(Return_rate,&quot;%&quot;,&quot;&quot;))&gt;60,&quot;High&quot;,if(parse(replace(Return_rate,&quot;%&quot;,&quot;&quot;))&lt;20,&quot;Low&quot;,&quot;Mid&quot;))"/>
          </list>
          <parameter key="keep_all" value="true"/>
        </operator>
        <connect from_op="Create ExampleSet" from_port="output" to_op="Generate Attributes" to_port="example set input"/>
        <connect from_op="Generate Attributes" from_port="example set output" to_port="result 1"/>
        <portSpacing port="source_input 1" spacing="0"/>
        <portSpacing port="sink_result 1" spacing="0"/>
        <portSpacing port="sink_result 2" spacing="0"/>
      </process>
    </operator>
  </process>
  

  The results are like that : 
  
  
  Hope it helps,

  Discretize by User Specification would be another simple way to solve this problem in RapidMiner.

  Thanks @Telcontar120. I just tried it. This is a really straight forward way that I had not seen before.
