How do you read a local file on your PC and update it constantly in javascript?

So I've made a java program that runs through a list of IPs, pings them, and updates a file on the devices status. I want to know how to open the file into a webpage and update it, so a user can open the webpage and just see a list of data from the file, they don't have to select the file or refresh the page.

Is this feasible to do with javascript/html?
