Extract first occurring number set from text string

Hi, I'm trying to extract the first group of numbers from a text string in Power Query editor . Have seen a few tips on the this but problem is that the strings don't have any set pattern.

 

Please see examples below.

 

hello1234.  1234

hello 123    123

12 hello 21  12

 

Anu suggestions please? I have a way to do this in VBA but have been asked to recreate in Power Query now. 

Thanks

You can use below in a custom column

 

 

try Number.From(Splitter.SplitTextByCharacterTransition({"0".."9"}, (c) => not List.Contains({"0".."9"}, c))(Text.RemoveRange([Text],0,Text.PositionOfAny([Text],{"0".."9"}))){0}) otherwise null

 

Edit - another construct can be

Number.From(Text.Split(Text.Trim(Text.Combine(List.Transform(Text.ToList([Text]), (x)=> if not List.Contains({"0".."9"},x) then " " else x)))," "){0})

Hi,

 

Please try the below...

 

let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Table", type text}}),
NumbersOnly = Table.TransformColumns(#"Changed Type", {{"Table", each Text.Select( _ , {"0".."9", " "})}}),
#"Trimmed Text" = Table.TransformColumns(NumbersOnly,{{"Table", Text.Trim, type text}}),
#"Extracted Text Before Delimiter" = Table.TransformColumns(#"Trimmed Text", {{"Table", each Text.BeforeDelimiter(_, " "), type text}})
in
#"Extracted Text Before Delimiter"

 

Basically extracting all numbers and spaces from your column (called mine Table), then only keeping numbers before the first space which I think will give you what you need.

Thanks, all of these work great. I went with the top solution.
