Change columns name dynamically

[Medmbchr]

Hi

I have many tables with codes as headers (ITMREF, ITMDESC) etc, and I have a 2-column Excel file in which I have the definition of each code (ITMREF = Item ID, ITMDESC = Item description).

I would like to dynamically change my column headers using that Excel table without the need to go through complicated queries like transpose and so on. I have a database of 50 tables.

Is it doable? thank you

I have a very similiar need.  At the moment I'm doing multiple steps like:

= Table.TransformColumnNames( PreviousStep, each Text.Replace( _, "OLDVALUE" , "New Value" ) )

Hopefully some wizard has a better solution

Hi @Clem_Fandango 

Thanks for your reply. I really can't use this solution since I have a very large data set: 50 tables and each have a minimum of 20 columns.

Let's hope someone figured out a solution.
