Writing runtime values to an Excel spreadsheet in CAMEO

Hi Guys! I'm having a problem and there is no apparently solution on the web. I have found a couple of tutorials about Reading but not Writing runtime values. I'm trying to use the ExcelHelper API to write runtime values ​​but I'm failing. Every time I try to write a file there it's impossible. Does anyone have any idea how this works or if it actually still works? I'm using something like this:

ExcelHelper.writeObjectsToSpreadSheet(result, fileName, 1, false);

And in all the possible variation I get this problem: <> is deprecated.

The 'result' is a property value of a block called "Writer" and it has a single value assigned to it: 7. Is this enough? or I'm omitting something here and is more complex the written process.
