Import CSV retain path and file name
Hi, everybody!
I am trying to import a single CSV file via Power Query and retain the filename and path data, but I'm having a tough time adding a step that gets me that information. Because the path gives me the date information from which the snapshot was taken, I need to pull this into a column in the table so that I can tag each record as belonging to that particular snapshot file.
let
Source = Csv.Document(File.Contents("H:\Box\DailyPace\Daily Pace Snapshots\2019\February 2019\Pace Report Data_110319.csv"),[Delimiter=",", Columns=17, Encoding=65001, QuoteStyle=QuoteStyle.None]),
#"Promoted Headers" = Table.PromoteHeaders(Source, [PromoteAllScalars=true]),
#"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Start Date", type date}, {"Owner Name", type text}, {"Property", type text}, {"Actual Revenue Total", type number}, {"Actual Revenue Subtotal", type number}})
in
#"Changed Type"Please let me know if there is a step I could add / replace to my M code to allow me to extract the path into a column.
Thank you for your help,

Hi doctornick0 ,
We can get the file from Folder to work on it. M code for your reference.
let Source = Folder.Files("D:\Case\20190313\test"), #"Removed Columns" = Table.RemoveColumns(Source,{"Extension", "Date accessed", "Date modified", "Date created"}), #"Filtered Hidden Files1" = Table.SelectRows(#"Removed Columns", each [Attributes]?[Hidden]? <> true), #"Invoke Custom Function1" = Table.AddColumn(#"Filtered Hidden Files1", "Transform File from test (2)", each #"Transform File from test (2)"([Content])), #"Expanded Transform File from test (2)" = Table.ExpandTableColumn(#"Invoke Custom Function1", "Transform File from test (2)", {"col1", "col2", "col3"}, {"Transform File from test (2).col1", "Transform File from test (2).col2", "Transform File from test (2).col3"}), #"Removed Columns1" = Table.RemoveColumns(#"Expanded Transform File from test (2)",{"Content", "Attributes"}) in #"Removed Columns1"Regards,

Good call, I then just filtered the folder for the file I actually wanted, which actually works out well, I can pass the file name via code to the query in that case.
