    Hi robofski ,

     

    1. Create a parameter in Power query make the parameter is \\server\share\folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder\another folder.

     

    2. Edit the M code in your Advanced editor to replace the file pate to parameter.

     

    let
    Source = Folder.Files(""&Parameter1),
    #"Filtered Hidden Files1" = Table.SelectRows(Source, each [Attributes]?[Hidden]? <> true),
    #"Invoke Custom Function1" = Table.AddColumn(#"Filtered Hidden Files1", "Transform File from New folder", each #"Transform File from New folder"([Content])),
    #"Renamed Columns1" = Table.RenameColumns(#"Invoke Custom Function1", {"Name", "Source.Name"}),
    #"Removed Other Columns1" = Table.SelectColumns(#"Renamed Columns1", {"Source.Name", "Transform File from New folder"}),
    #"Expanded Table Column1" = Table.ExpandTableColumn(#"Removed Other Columns1", "Transform File from New folder", Table.ColumnNames(#"Transform File from New folder"(#"Sample File"))),
    #"Changed Type" = Table.TransformColumnTypes(#"Expanded Table Column1",{{"Source.Name", type text}, {"Date", type date}, {"cat", type text}, {"Sales", Int64.Type}})
in
    #"Changed Type"

Hi guys, I was struggling with a similar problem, and I've just found a solution.

 

I was trying to import all of my folders, so that I could filter and use certain files.

 

Filtering directly on the file type (.xlsx) was giving this DataFormat error, since it was looking at all of my files, some of which are pdfs with long names or folders inside folders..

 

Luckily, all the files I wanted to combine were all in folders that have a similar naming convention, e.g. '- 2024 -', I was able to filter on the Filepath instead, only looking for folders which contained the right type of name.

 

This meant that less files were being considered, and I suppose this filtered out some of the long file names (e.g. pdfs) which were causing the problem.
