Power M - Find Numbers Before Specific Text

Hello, I am looking to extract numbers before specific text ("BUP").  I think it is possible we may need to address " BUP" specifically, as users would likely put a space between number and "BUP".  Example below:

 

1. "40 BUP" = 40

2. "@LOCATION 25 BUP" = 25

3. "hello_world" = 0

 

Appreciate the help.

    Use this in a custom column

    = if Text.End([Data],3)="BUP" then Text.Replace(List.Last(Text.Split(Text.Select(Text.Replace([Data]," BUP","BUP"),{"0".."9"," ","B","U","P"})," ")),"BUP","") else 0

    Full test code

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjFQcAoNUIrViVZy8PF3dgzx9PdTMDKFC2ak5uTkx5fnF+WkoCoyMoUpMTGNKTUwMDKDkHDNsQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Data = _t]),
    #"Added Custom" = Table.AddColumn(Source, "Custom", each if Text.End([Data],3)="BUP" then Text.Replace(List.Last(Text.Split(Text.Select(Text.Replace([Data]," BUP","BUP"),{"0".."9"," ","B","U","P"})," ")),"BUP","") else 0, type number)
in
    #"Added Custom"

    In a custom column, put following formula

    = Text.Select(List.First(Text.Split(Text.Replace([Data]," ","")&"0BUP","BUP")),{"0".."9"})

    See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjFQcAoNUIrViVZy8PF3dgzx9PdTMDKFC2ak5uTkx5fnF+WkoCoyMgUriQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Data = _t]),
    #"Added Custom" = Table.AddColumn(Source, "Custom", each Text.Select(List.First(Text.Split(Text.Replace([Data]," ","")&"0BUP","BUP")),{"0".."9"}), type number)
in

      Vijay_A_Verma  - This solution works perfectly (per my description) but it encounters an issue that I didn't anticipate:

       

      "45&& 25 BUP" = "4525 BUP" (with your solution).  Ideally it would return "25 BUP".

       

      Is there a way to ammend the code so it will only capture numbers before the string "BUP"?  Once a non-number field is encountered, it will not return subsequent characters.

       

      Thank you so much for your help!  You're a life saver : )
