There are few workarounds for this task, but it would be really very easy if Data Cleansing Tool could delete Null Rows and Null Columns. After all its just a macro which can be modified and re-packaged into Alteryx Designer.
Currently, to delete a null row requires multiple columns validation for common Null attributes,
similarly to delete a null column every column has to be compared on a row-level and flagged for removal. Both of these approaches are clumsy.
Wouldn't it be so simple if Data Cleansing Tool gave such check boxes !!!
