chrome extension for automating

I need a chrome extension that will get some data in a website the data is explicit it just takes so much time to do manually. The website is a Sort of analysis of api calls it just tells the errors and all i need is the errors classified in an excel file. The errors are in json format. But there is one small problem, the website can’t be accessed by anyone outside the company so we'll have to do it together in zoom or another Application.
