How can I create an Excel file from a script in Servicenow?

[mpsteve137]

I just need a really simple example of how I can create a .xlsx file not .csv. What is the syntax for this when writing with GlideSysAttachment().write?

I've tried:

var gsa = new GlideSysAttachment();

gsa.write(fixGr, 'test.xlsx', 'text/xlsx', data); 

but when I go to open the created attachment in Excel, Excel says its may be corrupted or the wrong file type. 
Can anyone please provide a simple example of what the data would look like and how to write it properly?

pls help
