hello, 

Urgent help need

I have a updated excel that i want to attach to attachment record using script because kb article is published.

var attachment = new GlideSysAttachment();

//set up inputs
var rec = new GlideRecord('kb_knowledge');
rec.get('sys_id');
var fileName = 'abc.xls';
var contentType = 'application/vnd.ms-excel';
var content = '';

var agr = attachment.write(rec, fileName, contentType,content);

gs.info('The attachment sys_id is: ' + agr);

you cannot create excel file and write it to record. you can create csv file

thanks for the reply, but it was working with custom data in the excel and the excel was attached to the record, but the problem is that i am not able to read the data from the excel in snow, if that may be possible with decode /encode method no idea,

if yes then you need to use GlideExcel parser
