type Text: Clean in-between white space

Hi. Is there a way to parse text to single white spaces only?

 

That is:

"mary    white     helloooo"

 

Becomes:

"mary white helloooo"

    try this

     

     

    let
        Source = Excel.Workbook(File.Contents("C:yourpath\Q.14 Data.xlsx"), null, true),
        Table1_Table = Source{[Item="Table1",Kind="Table"]}[Data],
        #"Changed Type" = Table.TransformColumnTypes(Table1_Table,{{"Single space everything, and trim both ends (don’t make a new column)", type text}}),
        tc=Table.TransformColumns( #"Changed Type", {"Single space everything, and trim both ends (don’t make a new column)", each Text.Combine(List.Select(Text.Split(_," "), each _<>""), " ")})
    in
        tc

    Text.Combine(List.Select(Text.Split("mary    white     helloooo"," "), each _<>""), " ")

     

     

     

    I do not intend to boast this solution, but just as a side observation, I point out that this cuts away the blanks that precede the first word or follow the last word.
    This of course can be an advantage or a disadvantage, it depends on what one is looking for.

    Hi michellepace 

    Paste this M code in a blank query to see the steps. The recursive function is the relevant one.

    let
        Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45Wyk0sqlQAgvKMzJJUEEMhIzUnJx8IlGJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t]),
        #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}}),
        fx = (input as text) => let reduce = Text.Replace(input,"  "," "), res=if Text.Length(reduce)=Text.Length(input) then input else @fx(reduce) in res,  
        #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each fx([Column1]))
    in
        #"Added Custom"

    Hi, michellepace 

    Try this:

    = let str="mary    white     helloooo" in Text.Combine(Splitter.SplitTextByWhitespace()(str), " ")

    If my code solves your problem, mark it as a solution

      = Splitter.SplitTextByWhitespace()(" mary white helloooo ")

       

      this function, that of which I now know the existence thanks to ziying35 , for a string with leading or trailing whites spaces, gives this result

       

       

      where the first and last element are the empty string "".

       

      Why?

       

      what kind of internal logic is applied in your opinion?

        The function does have the problems you describe, and I'm not sure about its internal logic. The scenarios I've used it in before have been without leading and trailing spaces

         

        = let str=" mary white helloooo " in Text. Trim(Text.Combine(Splitter.SplitTextByWhitespace()(str), " "))
