Extract latest csv from folder with multiple gz

Hi,

 

i want to extract from the latest gz file in a folder the csv file and continue with transforming. But it won't work out.... can someone help out?

 

= let
Quelle = Folder.Files("C:\xyz\folder"),
#"Sortierte Zeilen" = Table.Sort(Quelle,{{"Date created", Order.Descending}}),
#"Beibehaltene erste Zeilen" = Table.FirstN(#"Sortierte Zeilen",1)
Decompressed = Binary.Decompress(Source, Compression.GZip),
#"Imported CSV" = Csv.Document(Decompressed,[Delimiter="", Encoding=1252),
in
#"Imported CSV"

 

Thanks

    Hi, VTom 

     

    you need to add GetBinary = KeptFirstRow{0}[Content], before decompressing. to keep only the first row, which is the latest file. 

     

    so your modified code will be something like

     

    let
    Source = Folder.Files("C:\xyz\folder"),
    SortedRows = Table.Sort(Source,{{"Date created", Order.Descending}}),
    KeptFirstRow = Table.FirstN(SortedRows,1),
    GetBinary = KeptFirstRow{0}[Content],
    Decompressed = Binary.Decompress(GetBinary, Compression.GZip),
    ImportedCSV = Csv.Document(Decompressed,[Delimiter=",", Encoding=1252])
    in
    ImportedCSV

     

    Also, this tutorial will be helpful.
