Putting last string element from a column into a new column

[Anonymous]

Hello, 

I woud like to create a new column in Power BI desktop that it based on another column in my data. 

The new column should only take the last string element of the previous column. For example:

If one row in the column contains: ['Elsa', 'William', 'Kate'], the new column should only contain: ['Kate'] in the corresponding row.

All rows don't have the same amount of string elements (i.e. some have 4 names and some none at all). 

I would be very grateful if anyone could help me solve this, 

Thank you, 

Louise

Not sure if you string actually includes the [ and ' symbols, but you can use this formula in a custom column.  If you do need those characters, you can concatenate them to the result (or use Replace Values to remove them before or after this step).

= List.Last(Text.Split([ListColumn], ", "))

Hi @Anonymous ,

Please try using the extract function in the query editor.

Thank you for your response ! 

The brackets and quotation marks are indeed part of the column (my data is an imported csv). 

Could you please show me where I should enter this line of code ? I have tried to add it when creating a new column (I go to Modeling then to New Column) but it doesn't seem to be DAX syntax. 

Thank you, 

Louise
