type Text: Clean in-between white space
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
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), " "))
Thank you all for your replies. In truth, I am struggling to use any of the solutions. Looking at my initial post, I did not explain my requirement sufficiently. If you look at the column name below, it is exactly what I need to do. Does anyone have the line of M-Code I can paste into the Advanced Editor to achieve this? I am happy for Format>Trim to be used as the first step if it simplifies the solution.

Many thanks once again.

Anonymous im not sure, but maybe Splitter.SplitTextByWhitespace() considers more spaces in a row (" ") as a single "whitespace"... thats why there is only one empty element at the beginnning and end of the list:
try to write, for example, in pseudo-code (simulating a low-level language) the various steps that produce that result.
Let's see where the different management of leading and trailing spaces intervenes with respect to those inside the text string.PS
Un empty element "" is different from blank " "
