Open an Excel file with Javascript (SpiderMonkey 1.8) in Sparx Enterprise Architect

Enterprise Architect modelling tool from Sparx Systems (www.sparxsystems.com) integrates SpiderMonkey Javascript engine 1.8.
This is useful to create JS scripts in this tool and make use of its Interop API.
I managed to create a simple Logging class to output info and debug message.

I’m struggling in getting Excel Application to work ; I need to open Excel to read or write information. I can’t find any information from the MDN docs (except from https://developer.mozilla.org/en-US/docs/Archive/Web/JavaScript/Microsoft_Extensions/ActiveXObject which doesn’t provide working samples).

The following works as I can see a new Ms.Excel process in the task manager:
var ExcelSheet = new COMObject('Excel.Sheet',true);
But as soon as I try to create a workbook or worksheet object, it doesn’t work.

Is there any working example or reference I can look at to fix this?

Hello @Guillaume_UML

according to the lnk you provide it only work in IE so check this one

hope it help and have a nice day

Thank you for your reply.
The 1st link gave some hints that I tried yet it didn’t work.

ActiveX will not work with SpiderMonkey. ActiveX is a deprecated technology that worked only with Internet Explorer and stopped working at all years ago.

What exactly do you need to do, @Guillaume_UML ? Open the Excel binary?

you very welcome and sorry for late replay and the problem is i am on linux so i can not test it on IE

and i agree with @yoric that you should consider another way if you need to do something with excel file unless if your user will be only IE

have a nice day for both of you
