Remove carriage return (line break) \r\n from string

Hi all,

 

I'm in trouble with removing carriage return from a string in Power Automate.

From Teams I'm using Power Virtual Agent and a user can send a message in two lines (or more).

This message is sent to Power Automate to compose a Json, but I cannot be able to remove the line break.

This is an input example:

Using the expression split(variables('DescriptionParsed'), '\r\n') I can see the output with \r\l

But next, when I "Apply to each item" to replace "\r\n" with empty string to have the text in a row, it doesn't work:

I've also tried without array, using join(split(variables('DescriptionParsed'), '\r\n'), '') but nothing has changed.

 

I need that

Ciao, ho un problema

con la stampante

will result as

Ciao, ho un problema con la stampante

 

I've tried a lot of solutions, but nothing is working for me.

 

How can I remove the new lines??

Thank you

 

 

Anna

I've resolved it! 😭

I can do it in a single line, using

split(MYSTRING, decodeUriComponent('%0D%0A'))

I can split in the right way my string with \r\n

 

I need to replace them with whitespace to have text in a single row, so I'm using a join

 

My final expression is:

join(split(MYSTRING, decodeUriComponent('%0D%0A')), ' ')

How do you enter it into the join dialog box

In MS Teams, you can enter a new line with key ENTER and SHIFT or ENTER and ALT.

Thank you for responding. My interest was really for power automate desktop. I found out that they have an action that will split text on a new one and also an action to join list elements with a space so that solved my problem

I had a multiline text column from SharePoint with blank rows (extra line spacing) between each line of text.  I tried replace() on the text from SharePoint, and I also tried trim().  Then I found this article, but I could not get the join / split solution (above) to work, either.  However, the "decodeURI" part of that expression got me thinking.

 

I ended up using an expression to encode the original text, then another expression to replace the %0A (my text only had \n for a new line char), then another expression to decode the text again.  It works well.  Here are the screenshots and expressions if it will help anyone.

The expression from the 1st Compose action is just encoding the text from the original SharePoint item's multiline text field:

encodeUriComponent(outputs('Get_item')?['body/ApprovalText'])

 

Compose 2's expression replaces 2 newlines ('%0A%0A') with a single newline ('%0A'); you could just replace with '' to get rid of the new line completely:

replace(outputs('Compose'),'%0A%0A','%0A')

 

Compose 3 just decodes the result of Compose 2 back to "normal" text:

decodeUriComponent(outputs('Compose_2'))

 

Hopefully that helps someone.
