![]() How Do Screen Scrapers WorkĪ screen scraper is a computer program that uses a screen scraping technique to translate between legacy application programs (written to communicate with now generally obsolete input/output devices and user interfaces) and new user interfaces so that the logic and data associated with the legacy programs can continue to be used.Ī helpful screen scraper is supposed to meet two requirements:ġ. By contrast, screen scraping only requires coding on your end to parse and extract the data that can be for one-time or immediate needs without waiting. It always takes time to wait for API development, and most of the development might be done by a third party. Meanwhile, screen scraping has lower financial costs compared with APIs. Basic screen scraping can be done with simpler technologies like browser automation or scraping libraries. Using APIs requires coding knowledge or programming skills, while setting up screen scraping has fewer steps, and users can put less effort into it. In such a situation, screen scraping can help in collecting data. ![]() Some parts of an APP or specific data elements may not be accessible through its formal AIP endpoints. Older applications and websites may not have modern AIPs built, so the data is not available through an API to extract data. Here are some significant benefits of using screen scraping. In spite of APIs becoming more common, screen scraping is still used by many users. Screen scraping is usually done only when all other options are impractical.” In such a case, the only way to continue using the legacy application may be to write screen scraping software to translate it into a more up-to-date user interface. In some cases, it is desirable to continue using a legacy application but the lack of availability of source code, programmers, or documentation makes it impossible to rewrite or update the application. “Under normal circumstances, a legacy application is either replaced by a new program or brought up to date by rewriting the source code. It is commonly done to display data from legacy applications using user interfaces that are more modern. This process involves capturing screen display data from one application and translating it so that another application can display it. It is in the process of extracting data from graphical user interface (GUI) screens in applications and websites. Screen scraping is usually associated with programmatically collecting visual data from a source, but it can also refer to reading text data from a computer display terminal. In this article, we will take a close look at screen scraping, introduce how a screen scraper works, and compare screen scraping to web scraping. Does this sound a little bit similar to web scraping? Such a question keeps coming in. Screen scraping is a data collecting technique usually used to copy information that shows on a digital display, typically a webpage.
