I am getting out of an exec mode: msg.payload : string[11]  
"2498101658↵"

but what I need is: msg.payload : string[10]  
"2498101658"

I have tried the string mode without success.

In a function node

```auto
msg.payload = msg.payload.trim();
return msg;

```

or in a change node  
set `msg.` `payload`  
to JSONata `$trim($$.payload)`

A better title for your topic maybe `String handling remove newline` It would help future readers find the solution to a similar issue, `String handling` is fairly broad.

Hi,

There is also the " node-red-contrib-string" node if you need to do more-advanced string handling and want to do it in a 'visual' way.

Cheers,

Paul

I did look into every one of the " node-red-contrib-string" methods, including trim right, but did not find any which would remove the return character.  
As you suggest, I prefer to do it in a 'visual' way: this is preferable when sharing a flow with somebody who is not familiar with functions or Jsonata.  
In order to obtain the string the exec node runs a python script in which I had added a marker word at the end of the string. That done the exec node adds the return character after the marker and I could thereafter remove both marker and return sign with a " node-red-contrib-string".  
Somehow messy and leading me to post my question.

The JavaScript trim() function will remove a newline from the end of a string.
