Creating Browser extension for Screen Scraping of web pages


I need to create extension for web browser that will allow me to scrap the data on screen on click of it.
Can I create a web browser extension in UiPath.

I have my web application page I entered some data in textboxes. Now I want to click the browser extension button. Then it should capture the data entered in textboxes and save it to .csv file.

Please let me know how this can be done.

Your help is highly appreciated.
