Sorry,
I know idea how to add the code in my case, probably you can show how to add on to the code below:
let
Source = Folder.Files("D:\GST Recon\Data Extraction from GST by CF MRT - zip file\04 MRT_Period 4\MRT_Period 4\Input"),
#"Removed Other Columns" = Table.SelectColumns(Source,{"Content"}),
#"Combined Binaries" = Binary.Combine(#"Removed Other Columns"[Content]),
#"Imported CSV" = Csv.Document(#"Combined Binaries",[Delimiter="|", Columns=15, Encoding=1252, QuoteStyle=QuoteStyle.None]),
#"Changed Type" = Table.TransformColumnTypes(#"Imported CSV",{{"Column1", type text}, {"Column2", type text}, {"Column3", type text}, {"Column4", type text}, {"Column5", type text}, {"Column6", type text}, {"Column7", type text}, {"Column8", type text}, {"Column9", type text}, {"Column10", type text}, {"Column11", type text}, {"Column12", type text}, {"Column13", type text}, {"Column14", type text}, {"Column15", type text}}),
#"Promoted Headers" = Table.PromoteHeaders(#"Changed Type"),
#"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"Principal Fee Amount ", type number}, {"GST Tax Amount ", type number}, {"Gross Amount ", type number}})
in
#"Changed Type1"
Thank you
