Hi all!
In order to parse fixed-width files with variable number of characters that marks the start of each column, I'd like to use a list of values stored in a cell in an Excel document. To do so, I retrieved the values from the cell and converted it in a list of values, like this:
ColumnsFromExcel = Excel.CurrentWorkbook(){[Name="ColumnasSeparadorasRCV"]}[Content]{0}[Column1],
#"ColumnsList (text)" = Text.Split(ColumnsFromExcel, ", "),
#"ColumnsList (num)" = List.Transform(#"ColumnsList (text)", each Number.FromText(_)),
When I try to use the resulting list from Excel cell, Csv.Document function returns just one column, however, if using a typed list of values, the function returns the expected number of columns. Both lists seems to be identical:
I couldn't find a solution for this so far. Any help would be appreciated!

Thanks. This makes it clear exactly what's going on.
In your first line, it's interpreting "ColumnsList (num)" as a literal string rather than a reference to a list. In order to disambiguate, try it with an octothorpe (#) in front.
Source = Csv.Document(File.Contents(FilePath & FileName),null,#"ColumnsList (num)",null,1252),

I'm not following how exactly you're using the lists. Can you share the code for the step with the Csv function?
Hi @AlexisOlson.
Thanks for the fast reply.
I'm trying to use this code:
Source = Csv.Document(File.Contents(FilePath & FileName),null,"ColumnsList (num)", null,1252),
instead of:
Source = Csv.Document(File.Contents(FilePath & FileName),null,{0, 9, 28, 36, 40, 45, 55, 65, 71},null,1252),
Thanks. This makes it clear exactly what's going on.

That did the trick, thank you @AlexisOlson for pointing the error in my code.
Really appreciate your help.
