User might have entered extra 'ENTER' so it is adding extra line at the end.

You can use logic like below:

var current = new GlideRecord('change_request');
current.get('fdbce3f72f323110ae17debcf699b65c');
var itar = current.variables.existing_itar_objects.toString().trim(); // use toString() to change it to string
var lineCount = itar.split('\n').length;
gs.info(lineCount);

Hello @mounika32

Please use this script -

var itar = current.variables.existingg_itar_object;
var linesArray = itar.split('\n');
var lineCount = linesArray.length;
gs.info('Number of lines in the multi-line text: ' + lineCount);

Hi @mounika32 ,

Try Below script -

var chatHistory = "Line 1\nLine 2\nLine 3\nLine 4";
