Extract Using Any Non-Number As Delimiter

[Anonymous]

Hi. I am trying to extract numbers that only exist before any characters occur in the string. Once ANY characters start, that will be the end of the number. The trick here is that somtimes there are also numbers after the characters I want to use as a delimiter and should be ignored, so I simply can't use the function to extract all numbers. If there are no numbers before characters start, it would default to 1. Below are some examples:

Source	Extracted
30	30
40A	40
12,5CLR	12
ABC	1
ABC123	1

I have attempted to use the Add Column --> Column From Examples function but it seems to revert to a simple "IF this value, THEN that value". Thanks!

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"

Hi @CNENFRNL . Thanks for replying. When I create a new column with this code, it looks like my table turns into the exact image you provided. I do not need those exact values as they are examples to show the different scenarios of values I would need to convernt.

@Anonymous , you need to add a new column this way in your senario,

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. All values in this column are showing up as 1 with this paritcular code.

mmhh ... I don't believe it. ‌🤔‌
Can you show the code you used and also the results obtained?
