PowerQuery | Extract Numbers from A string (eg ABCD1234)

Hi Community,   In this example, FirstName12345. How can I extract 12345 from it using M?   Assume that the number length varies (eg abc123, abc1234567, abc1234, etc...)     [Edit] Spelling  ...

    HI ovetteabejuela,

     

    You can refer to below formula to if it suitable for your requirement.

     

    Logic: split text to character list, select the number part and merge them to text.

     

    Functions comment.

    Text.ToList: split text to character list.
    Values.Is: check value type.
    List.Transform: transform list from original list.
    List.RemoveNulls: remove replaced null value.
    Text.Combine: merge character list to text.

     

    Formula:

    #"Added Custom" = Table.AddColumn(#"Promoted Headers", "Custom", each Text.Combine(List.RemoveNulls(List.Transform(Text.ToList([Name]),each if Value.Is(Value.FromText(_), type number) then _ else null))))

     

     

    Full query:

    let
    Source = Excel.Workbook(File.Contents("C:\Users\xxxxxx\Desktop\test.xlsx"), null, true),
    Sheet3_Sheet = Source{[Item="Sheet3",Kind="Sheet"]}[Data],
    #"Changed Type" = Table.TransformColumnTypes(Sheet3_Sheet,{{"Column1", type text}}),
    #"Promoted Headers" = Table.PromoteHeaders(#"Changed Type", [PromoteAllScalars=true]),
    #"Added Custom" = Table.AddColumn(#"Promoted Headers", "Custom", each Text.Combine(List.RemoveNulls(List.Transform(Text.ToList([Name]),each if Value.Is(Value.FromText(_), type number) then _ else null))))
in
    #"Added Custom"

Using Transpose and then Split column Space Right most delimiter  in M Is manually intensive but will do what you want.  I also trimmed the extra spaces

 

Heres my code

 

Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type any}}),
#"Transposed Table" = Table.Transpose(#"Changed Type"),
#"Split Column by Delimiter" = Table.SplitColumn(#"Transposed Table", "Column1", Splitter.SplitTextByEachDelimiter({" "}, QuoteStyle.Csv, true), {"Column1.1", "Column1.2"}),
#"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Column1.1", type text}, {"Column1.2", type text}}),
#"Split Column by Delimiter1" = Table.SplitColumn(#"Changed Type1", "Column3", Splitter.SplitTextByEachDelimiter({" "}, QuoteStyle.Csv, true), {"Column3.1", "Column3.2"}),
#"Changed Type2" = Table.TransformColumnTypes(#"Split Column by Delimiter1",{{"Column3.1", type text}, {"Column3.2", type text}}),
#"Split Column by Delimiter2" = Table.SplitColumn(#"Changed Type2", "Column4", Splitter.SplitTextByEachDelimiter({" "}, QuoteStyle.Csv, true), {"Column4.1", "Column4.2"}),
#"Changed Type3" = Table.TransformColumnTypes(#"Split Column by Delimiter2",{{"Column4.1", type text}, {"Column4.2", type text}}),
#"Trimmed Text" = Table.TransformColumns(#"Changed Type3",{{"Column1.1", Text.Trim, type text}, {"Column1.2", Text.Trim, type text}}),
#"Changed Type4" = Table.TransformColumnTypes(#"Trimmed Text",{{"Column2", type text}, {"Column5", type text}}),
#"Trimmed Text1" = Table.TransformColumns(#"Changed Type4",{{"Column2", Text.Trim, type text}, {"Column3.1", Text.Trim, type text}, {"Column3.2", Text.Trim, type text}, {"Column4.1", Text.Trim, type text}, {"Column4.2", Text.Trim, type text}, {"Column5", Text.Trim, type text}}),
#"Transposed Table1" = Table.Transpose(#"Trimmed Text1")
in
#"Transposed Table1"
