Programmatically change the case of headers (from a csv file)

[MarkJF]

Hi

I created a detailed report Report with data from csv files, and the Promoted Headers function provided me with headers all in lower case.

I now need to change the Source of the files, and the new files all have the Headers names in UPPer case; is there a way to select the first row of the imported table and convert it to Upper case before the Promoted Headers command?

Maybe using Table.SelectRows or similar commands?

Thanks

Mark

Hi,

maybe there is another way, but I would do it in the 3 simple steps:

1. Transpose columns/rows

2. Format items in the headers column to Upper Case

3. Transpose back columns/rows

1. Transpose column to rows2. Format items in 'header' column to UPPer Case3. Transpose back rows to columns

Or just change the column headers:

let
    Source = #table(2,{{1,2}}),
    HeadersUpperCase = Table.TransformColumnNames(Source,Text.Upper)
in
    HeadersUpperCase

Thanks, now I can see the function Table.TransformColumnNames it all makes sense!

(I think the transpose method might work as well, but my table has thousands of rows which might be an issue.)

How would you apply to this to all the data vs the headers?  I want it to make all the text in a table uppercase, but the number of columns change / are not consistent.

When I try to apply the same concept to the Table.TransformColumns it gives me an "Expression.Error: We cannot convert a value of type Function to type Text."
