How to remove GUID from rows in a column when it is combined with other text?

[aman720]

So I have a query that imports rows such as 

\\Server\Database\Unit01\Reactor?2f2eb94f-adb5-11eb-bacf-f0d5bf3c2f98|TEMP?b67078ec-0420-569f-204e-f6c9c28a9896

Where that string of characters is the GUID of the asset. Is there a way to dynamically remove the GUID from the row so it will look like 

\\Server\Database\Unit01\Reactor|TEMP

but also be applicable to other GUIDs?

@aman720 Try this:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("DcE7DsIwDADQu3S35JgkTaYuMCIhPlPdwU5tiaVIJWLi8PDePA/8d7P9YzvzUbqovI35sT07BuarSeuvfSIn0xodZNUEIZiCSnNwXJP6oZHX8r2fzpdJ84hjsQYYCSHl6kAYDTy32qhILTUPy/ID", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    #"Extracted Text Before Delimiter" = Table.TransformColumns(#"Changed Type", {{"Column1", each Text.BeforeDelimiter(_, "?", {0, RelativePosition.FromEnd}), type text}}),
    #"Added Custom" = Table.AddColumn(#"Extracted Text Before Delimiter", "Custom", each "?" & Text.BetweenDelimiters([Column1], "?", "|", {0, RelativePosition.FromEnd}, 0)),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each Replacer.ReplaceText([Column1],[Custom],"")),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom1",{"Column1", "Custom"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Custom.1", "Column1"}})
in
    #"Renamed Columns"

@Greg_Deckler I apologize I am still quite new to Power BI. I have the data pulled in from SQL. I will call the column Column1 to fit your syntax. How does that fit into the overall steps? For example, do I drop that in after Source in the Applied Steps. Thanks!

Edit: Actually I got it to work with your code. So thanks for that! In doing so, I found not all the rows have that GUID in them and what you wrote puts in a blank row if there is no GUID (my bad). I am trying to find a way to skip these rows if they don't have the GUID now.

@aman720 Can you provide an example of one without GUIDs?

[aman720]

@Greg_Deckler

\\Server\Database\HX|OUTLET.TEMP    

The ones without the GUIDs have the same form of the target rows your code fixed.

@aman720 Try this:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("dc1BDoIwEEDRu7B2TFuhtCs2kLjQaLQkJgyLmTKTuNEEiSsOrx7Af4D3h6HAb1eZ3zIjtrQQ00sQ+8d9MRbxIpSX59w4dcKxVKCJK7BWGJiygpqpYt1lpzGsqTueG/a1qYNkMKUzUPmo4EwpoD7H7ALFEH0xbv6N97f11KdDl7Y/rRjHDw==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
    #"Added Custom2" = Table.AddColumn(#"Changed Type", "Custom2", each Text.BeforeDelimiter([Column1], "?", {0, RelativePosition.FromEnd})),
    #"Added Custom3" = Table.AddColumn(#"Added Custom2", "Custom3", each if Text.Length([Custom2]) = 0 then [Column1] else [Custom2]),
    #"Removed Columns1" = Table.RemoveColumns(#"Added Custom3",{"Column1", "Custom2"}),
    #"Renamed Columns1" = Table.RenameColumns(#"Removed Columns1",{{"Custom3", "Column1"}}),
    #"Added Custom" = Table.AddColumn(#"Renamed Columns1", "Custom", each "?" & Text.BetweenDelimiters([Column1], "?", "|", {0, RelativePosition.FromEnd}, 0)),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each Replacer.ReplaceText([Column1],[Custom],"")),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom1",{"Column1", "Custom"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Custom.1", "Column1"}})
in
    #"Renamed Columns"
