Extract Using Any Non-Number As Delimiter

= Table.AddColumn(#"previou step", "extract", each try Number.From(Splitter.SplitTextByCharacterTransition({"0".."9"}, (c) => not List.Contains({"0".."9"}, c))([Source]){0}) otherwise 1)

Hello Anonymous 

you can use this formula in a new column

let GetNumber=  List.FirstN(Text.ToList(_[Source]), (itemlist)=> Value.Is(try Number.From(itemlist) otherwise "text",type number) ) in if List.IsEmpty(GetNumber) then 1 else Number.From(Text.Combine(GetNumber))

here a complete example

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjZQitWJVjIxcATThkY6ps4+QWC2o5MzjDY0MlaKjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Source = _t]),
    AddColumn = Table.AddColumn
    (
        Source,
        "Extract",
        each let GetNumber=  List.FirstN(Text.ToList(_[Source]), (itemlist)=> Value.Is(try Number.From(itemlist) otherwise "text",type number) ) in if List.IsEmpty(GetNumber) then 1 else Number.From(Text.Combine(GetNumber))
    )
in
    AddColumn

Copy paste this code to the advanced editor in a new blank query to see how the solution works.

Hi, Anonymous , you might want try a simple solution

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjZQitWJVjIxcATThkY6ps4+QWC2o5MzjDY0MlaKjQUA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Source = _t]),
    
    #"Added Custom" = Table.AddColumn(Source, "Extracted", each let str = List.First(Text.SplitAny([Source],Text.Remove([Source],{"0".."9"}))) in if str="" then 1 else Number.From(str))
in
    #"Added Custom"
