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!

Hi,
you first split to columns, then use De-Pivot to transform these to rows.
Usually it's good to only work on a subset of your attributes (the column you want to split and some kind of Id column to join back later) because de-pivot makes working with all columns harder.

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"> <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="utility:create_exampleset" compatibility="9.4.000-BETA" expanded="true" height="68" name="Create ExampleSet" width="90" x="179" 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="time_zone" value="SYSTEM"/> <parameter key="input_csv_text" value="Att_1 ibmadmin,so soadmin autadmin ssdadmin,iamadmin psmadmin"/> <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_id" compatibility="9.4.000-BETA" expanded="true" height="82" name="Generate ID" width="90" x="313" y="85"> <parameter key="create_nominal_ids" value="false"/> <parameter key="offset" value="0"/> </operator> <operator activated="true" class="python_scripting:execute_python" compatibility="9.3.001" expanded="true" height="103" name="Execute Python" width="90" x="514" y="85"> <parameter key="script" value="import pandas as pd import numpy as np # rm_main is a mandatory function, # the number of arguments has to be the number of input ports (can be none) def rm_main(data): new_data = pd.DataFrame(data.Att_1.str.split(',').tolist(), index=data.id).stack() new_data = new_data.reset_index([0, 'id']) new_data.columns = ['id','Att_1'] return new_data"/> <parameter key="notebook_cell_tag_filter" value=""/> <parameter key="use_default_python" value="true"/> <parameter key="package_manager" value="conda (anaconda)"/> </operator> <connect from_op="Create ExampleSet" from_port="output" to_op="Generate ID" to_port="example set input"/> <connect from_op="Generate ID" from_port="example set output" to_op="Execute Python" to_port="input 1"/> <connect from_op="Execute Python" from_port="output 1" 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>
Hope this helps,
