Output webpage informations to Excel with JavaScript

We are using a software that converts a host screen (looks similar to unix) into a webpage. The output is html and javascript and looks good. Now i want to add a javascript function that takes values from the page and put them to a excel file. Need hands-on of javascript-expert to do this with me. I heard that it might only be working with Internet Explorer. I am ready to accept that limit. ## Deliverables javascript solution that does the excel output with some documentation. ## Platform windows
