I need to extract text from an URL

[Anonymous]

Example:

I have an URL column with value as below 

https://testlink-1258139023.mycloud.com/text01.png

https://testlink-1258139023.mycloud.com/texting01.png

https://testlink-1258139023.mycloud.com/text0124.png

I need to create a new column that contains:

text01

texting01

text0124

Many thanks!

Hi @Anonymous 

In DAX, here's how you can exract the text between last slash and before the .png.

Extracted Filename =

VAR FullURL = urltable[URL]

VAR URLLength = LEN(FullURL)

VAR LastSlashIndex =

    CALCULATE(

        MAXX(

            GENERATESERIES(1, URLLength, 1),

            IF(

                MID(FullURL, [Value], 1) = "/",

                [Value],

                BLANK()

            )

        )

    )

VAR FileNameWithExtension = IF(LastSlashIndex > 0, RIGHT(FullURL, URLLength - LastSlashIndex), BLANK())

VAR IsPng = RIGHT(FileNameWithExtension, 4) = ".png"

RETURN

IF(IsPng, LEFT(FileNameWithExtension, LEN(FileNameWithExtension) - 4), FileNameWithExtension)

Or you can do this in M Qery:

let
Source = Csv.Document(File.Contents("C:\Users\aliom\OneDrive\Desktop\url.txt"),[Delimiter=",", Columns=1, Encoding=1252, QuoteStyle=QuoteStyle.None]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
#"Promoted Headers" = Table.PromoteHeaders(#"Changed Type", [PromoteAllScalars=true]),
#"Changed Type1" = Table.TransformColumnTypes(#"Promoted Headers",{{"URL", type text}}),
#"Added Custom" = Table.AddColumn(#"Changed Type1", "Extracted Text", each let
SourceText = [URL],
LastSlashIndex = Text.PositionOf(SourceText, "/", Occurrence.Last),
DotPngIndex = Text.PositionOf(SourceText, ".png"),
ExtractedText = Text.Middle(SourceText, LastSlashIndex + 1, DotPngIndex - LastSlashIndex - 1)
in
ExtractedText),
#"Renamed Columns" = Table.RenameColumns(#"Added Custom",{{"Extracted Text", "URL (M)"}}),
#"Changed Type2" = Table.TransformColumnTypes(#"Renamed Columns",{{"URL (M)", type text}})
in
#"Changed Type2"

Use the AI feature in Power Query called 'Column from Example'.

Go to Power Query Editor, right click on your URL column and choose 'Add Column from Examples' and type in the Text that you want to extract.. Thats it !!

See the video in case you are unable to follow.
