Hi all,

This should be easy but I'm having some trouble with the syntax. I'm trying to sort multiple columns in ascending order in my table. It's easy enough to manually click each column and sort it in descending order, but then my M-code is hard-coded to these column header names. If the header names change, the code will break.

Manually sorting each column:

Power Query:
Table.Sort(PreviousStep,{{"Column1", Order.Ascending}, {"Column2", Order.Ascending}, {"Column3", Order.Ascending}, {"Column4", Order.Ascending}})

I have a list that dynamically populates the correct headers. What is the correct way to write the statement below?

Dynamically sorting each column according to my list, HeaderstoSort:

Power Query:
Table.Sort(PreviousStep,{HeaderstoSort, Order.Ascending})
 

Excel Facts

Links? Where??
If Excel says you have links but you can't find them, go to Formulas, Name Manager. Look for old links to dead workbooks & delete.
Power Query:
SortList = List.Transform(HeaderstoSort, each {_}),
Result = Table.Sort(PreviousTableName,SortList)

if you wanted Order.Descending you would need to include that like

Power Query:
SortList = List.Transform(HeaderstoSort, each {_, Order.Descending}),
Result = Table.Sort(PreviousTableName,SortList)

Thank you SO MUCH! You're the MVP!
