Website Scraping – Extract Your Data

 

Website scraping, also known as Web Data Extraction, Web harvesting or Screen Scraping is the process of extracting large amounts of data from any given website, which is then stored locally in the local disk of the computer or in the form of a spreadsheet format. Data that is displayed by most websites can mainly be used for the purpose of viewing by consumers. These data are not open for copying on a large scale process locally. In such cases, one might be forced to copy the relevant data and simply paste in the computer file location. However, this is a tedious job as it takes up hours, days and even months, depending on the size of the date needed to be downloaded. This is where website scraping comes into the picture. Website scraping helps to automate this process of copying and pasting by loading and extracting the relevant data from many website pages at a single time, thereby saving man-hours and manpower.
