I have a initial table with a variable quantity of columns, I would like to transform the columns making the operation robust, i.e not depending on the column names.
Function to be applied on all columns: extraction of the first character
Technique intended : make a list with the existing column names and apply the transformation to the list of columns.
Which is the efficient method to do so?
Solved! Go to Solution.
Hi @TomasBA ,
Try the Text.Start function. It returns the first count
characters of text
as a text value.
Text.Start - PowerQuery M | Microsoft Learn
And then try pivot/unpivot.
Pivot columns - Power Query | Microsoft Learn
Unpivot columns - Power Query | Microsoft Learn
