I wanted to make all my attribute to camelCase, currently they are separated by underscore.

I wanted to change my attribute name to camelCase, so using regular expression in BulkAttributeRenamer transformer to find text following underscore using regular expression replace: _([a-z]) 

 

However, i am not sure what String parameter i have to put to make the selected character Capital letter. I have tried \U\1 and also few other but its not working. Basically wanting to find String parameter value?

I’m not sure if you can modify the matched group in any way.

Hacky workaround would be to add a prefix, change to title case and remove a prefix (assuming attributes don’t start with an underscore

I think that’s going to be the best way. You could use Python but that would then require dynamic schemas and would add a whole extra level of complexity
