Finally, based on the specific HTML elements you requested the web crawler to retrieve it would export those elements containing match information into a downloadable CSV file for you in milliseconds.

The web crawler will then fetch and download the HTML code from the URL provided. You would first provide your web crawler or web scraper tools the URL of the page you want to scrape (i.e. A web crawler can do this task automatically for you. With the HTML code fetched, you can now start breaking it down to identify the key elements you want to save into a spreadsheet or local database, such as a table with all its data.įor example, you can use web scraping to collect the results of all Premier League matches without having to manually copy-paste every results from a web page with such information. The web crawler starts by fetching (or downloading) a page’s HTML code - the code that represents all the text, links, images, tables, buttons and other elements of the website page you want to get information from – and store it for you to perform further actions with it.

The process of web scraping follows a few simple steps: In short, web scraping is an automated way of copying information from the internet into a format that is more useful for the user to analyse. Chrome, Firefox, Safari, etc) to access a web page, retrieve specific HTML elements and download them into CSV files, Excel files or even upload them directly into a database for later analysis.

This code can either be written by yourself or executed through a specialised web scraping program. The process of scraping a website for data often consists on writing a piece of code that runs automatic tasks on our behalf.
