Thanks have not seen the custom splitter one,    I have alwasys tended to use a custom spilt in 
things like table.Replacevalues,  so eg ; 

 Table.ReplaceValue(  Custom1, each [a] , "X",  
(x,y,z)=> if Value.Type( y ) = type text then z else x , 
Table.ColumnNames( Source ))

 

so it will be interesting to see her take on custom spltters, you have probably seen it to r de groot did a video on 
comparers.   re my initial queyr I was more interested in advantages or not of higher order or generatror functions over 'normal' ones. 
Thanks for the help .
