Cleaning data to remove white space but keep text space for those broken into extra lines

Hi, 

I'm trying to remove all the CRLF and whitespaces off my data. Some of the data has extra line breaks and I'd like to remove these. My knowledge in power query and M is very limited but I've read I can remove the white space by using (FORMAT>Clean) which works great however for text that are split by the extra line, it concatenates the text. 

 

Orginal Data

 

"These is an example of my line

 

break."

 

Cleaned Data - using Format > Clean

 

"These is an example of my linebreak"

 

Desired Output

 

"These is an example of line break"

 

I'd really appreciate any help to achieve my desired output. Thank you so much in advance

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is beyond their comprehension!

DAX is simple, but NOT EASY!

Thanks for your help @SKoul and @watkinnc. I've tried both but it doesn't seem to work on my desired output. I've managed to use the Replace Values to clean up the whitespaces and that seems to have worked.

You could just use the Trim function form the GUI, which applies Text.Trim, which just removes leading and trailing whitespace.

I’m usually answering from my phone, which means the results are visualized only in my mind. You’ll need to use my answer to know that it works—but it will work!!

Hi @Anonymous,

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
