Extract Text from Name of File being Imported

Is there an straightforward way in PQ or via a formula, new column, or measure to get the text from the name of the file being imported?

Or do I have to redo a few things and reimport this as a folder import??

Hi,

I understand your Source step equals to "Csv.Document(File.Contents(..."
Copy paste the function below and invoke it in your Source instead.

(Path as text) => 
let
FileName =  Text.BetweenDelimiters(Path, "_", ".txt", {0, RelativePosition.FromEnd}, 0),
Txt = Csv.Document(File.Contents(Path),[Delimiter=";", Encoding=1252, QuoteStyle=QuoteStyle.None]),
PromoteHeaders = Table.PromoteHeaders(Txt, [PromoteAllScalars=true]),
FileNameColumn = Table.AddColumn(PromoteHeaders, "FileName", each FileName)
in
FileNameColumn

 

Hope it helps.

Hi @comish4lif2 ,

Assuming the file name is part of your Source step you could add a column extracting it using any of the functions you have available.

For instance: 

Text.BetweenDelimiters(Source,"\",".")

Is the file name part of my source step? 

If I import a txt file, how do I get from "FIlename_06162023.txt" - to "06162023" in its own column.
