So what you will need in order to easily scrape local business reviews on Google is you will need a Chrome extension called Instant Data Scraper. This is a completely free Google Chrome extension that has to be installed. After the installation of the Google Chrome extension scraper you will then need to go to either Google or Google Maps in order to find a business's reviews that you will want to scrape.
You will need to set up the scraper in order to have a successful scrape. First you will need to set the amount of time that you are delaying the scraper depending on what you're scraping and how fast you want to scrape it. You will have the ability to export the scraped reviews or information into a CSV file or you can also do it inside of a XLSX file.
