Creating an app that gives the output fields you select under multiple dropdown

[E_Sinha_home]

Hello

I have different input files with loads of columns.

I want to build an app that has 4 dropdowns (ID, Address, State, Postcode)

The user will select the fields that aligns to the 4 above and an output will be created.

Attaching a sample input file for reference.

Thanks in advance

Hi @E_Sinha_home 

Refer to my first response it's doing the renaming part. If you select first and then rename it should work properly.
