Regular Expression in a column of datatable, split it and explode rows

Hello Developers,

I am new to uipath and try to convert python code related to datatable into uipath. Please help me to get this task done

I have developed a workflow for Excel automation. I am stuck in between a point during this automation. I want to apply regular Expression in a column of a datatable. Tried many ways but not able to produce exactly desired result as I wants. I have datatable like Input Data sheet in attached excel

This is sample datatable and this has large number of columns. I want to apply regular expression in column C named as ID column. I want to split data in this datatable based upon $, & separator but also wants to ignore(delete) all the values between * and & or * and $. Row where we find empty cell in column C(ID) can be deleted or ignore.

Output Data sheet of attached excel contains output that I want.

I have developed it in python and now I want to convert it into uipath. Below is python code of solution of above problem-

import pandas as pd
df = pd.DataFrame({'Order': ['10-112','10-115'], 'Owner':['shubhman', 'rishab'], 'ID':['89ab$cd&78','']})

df['ID'] = df['ID'].str.replace(r'\*[^&$]*[&$]', '').str.split(r'[$&]') # Remove substrings between * and $ or &
df = df.explode('ID') # Split the rows with multiple IDs into multiple rows
df = df[df['ID'].astype(bool)] # Discard the rows with an empty ID

Could you please help me regarding my problem with workflow

Hi @Vishav_Gupta … do you want to write the output in the same column or in the new column?

Also could you please share the expected output with one sample data …?

I want output in the same column. as you can see with attached output in Excel. Please let me know if some other information is required from my side

Hi @Vishav_Gupta

For the input IDs 112abc*28&ab, 389&ab*3$8 the output obtained from your python code does not match with your output. Please check and confirm.

The same is the case with UiPath


@kumar.varun2 Thank you very much for reply. Python code is producing correct output as I want. You can check output data sheet in attached excel. I can feel what you are thinking. Trying to explain. For 112abc*28&ab, 389&ab*3$8 I want to ignore also character between * and $ or * and & parallel with splitting of data. That’s why it is not considering 28 and 3 value in final output after splitting. I will be very happy if you can help me to produce required output in uipath. Thanks for your help

Hello @Vishav_Gupta

Check this xaml file:

The code can further be optimized using LINQ

Hope it helps!
