Hello jcbutts

I recognized that I got you wrong. So week 1 is always the current week.

I fixed this now. Check out this one if it works

let
	Source = #table
	(
		{"week 1","week 2","week 3","other data","abc","week 52"},
		{
			{"","","","","",""}
		}
	),
    ColumnNames = Table.ColumnNames
    (
        Source
    ),
    TransformWeekInDate = List.Transform
    (
        ColumnNames,
        (row)=> try
        if Text.Contains(row,"week") or Text.Contains(row,"Week") then 
            Text.From(Date.AddDays(Date.AddDays( Date.From(DateTime.FixedLocalNow()), Date.DayOfWeek(DateTime.FixedLocalNow())*-1), (Number.From(Text.Replace(row, "week ", ""))-1)*7))
            else 
            row
        otherwise
        row
    ),
    RenameColumnHeader = Table.RenameColumns
    (
        Source,
        List.Zip({ColumnNames,TransformWeekInDate})
    )
in
	RenameColumnHeader

I tried all of these. For the first solution, I got an error saying the colunmn "Week 1" wasn't found. My actual column header is "Week 1- Mean Forecast" so I modified the code to match (checking a few different iterations for the spacing between the dash and the words) but it all came up with the same error...."Week 1 - Mean Forecast" not found.

For the other two solutions, the code was accepted, but it resulted in a table with one line. The headers were things like "Name" and "Hidden", and the data was just the name of my data file and the type.
