"Not able to run it" is insufficient. Is there an error?

Remove the try/catch block. It is swallowing the error.

I would dump the value of myQuery at the end of the method and see what the value is.

You cannot run a server side function from javascript. Not without using ajax. If you are just trying to test the function use:

<cfset getExcelSheet("exercices.xls","Pull")>

Be sure to fix it so it always closes all of the objects (connection, statement and resultset). Even when an error occurs. Otherwise the open objects may just continue to pile up which can lead to big problems.

I didn't even notice that, because it never even occurred to me that he would be trying that. I was focused on the actual method.

Korssane, I would really recommend that you stop here and either get a book on CF or read through the CF documentation. Because if this sort of thing is tripping you up, you are only going to have a ton of frustration going forward until you actually get a good grasp of the basics of CF.
