Clean Column Names default beavior is changed in Exploratory Desktop v4.4

With Exploratory Desktop v4.4 release, now the Clean Column Names feature uses snake case by default and resulting column names might have underscore like name_id when you cleaned a column like NameID. In the previous version, you get nameid when you clean the NameID column.

If you want to use the old way so that your data transformation pipelines keep working, you can set case argument to all_lower like below.

And in the Clean Up All Column Names dialog, change Case argument to all_lower

This will use old way of column clean up (i.e. nameid instead of name_id)
