Replace value in Quicksight

I have a dataset containing employee details with a ‘Location’ column(Sample is given below). In that column I need to change the string ‘Bengaluru’ to ‘Bangalore.’ However, after loading the data from files, I couldn’t find an option to do so. I’m new to QuickSight, and any assistance with this issue would be greatly appreciated.

Hi @Fatima,

new_location = ifelse({location}="Bengularu","Bangalore",{location))
