What is parsing? In simple words, it’s the conversion of one data format to another, easily readable data format. For example, if you receive data in HTML format, with the help of a parser, you’ll be able to translate the data into a more understandable form.

Usually, data parsing goes hand-in-hand with data extraction or, as we know it, web scraping. First, the data is scraped from the targeted websites and then transformed into a format that is easier to read and work with.

What exactly does a parser do? It delivers a portion of commands and instructions and divides them into other pieces in programming. After this, it checks if this data is enough to create a data structure known as a parse tree.

A well-built HTML parser identifies the required HTML data in the parsing process, extracts the needed information and converts it into JSON, CSV or a table depending on the pre-written code. It’s worth noting that a parser itself doesn’t carry a specific data format. Instead, the conversion process depends on how the parser was built. In this video, we’ll provide an example of a parser.

In most cases, parsing relies on the tools that require at least minimal understanding of programming languages, such as Java, HTML and XML Scripting languages, Python, and others.

Data parsing comes in handy in various business fields, such as SEO analysis, operation optimization, investment, and competitive analysis. Make sure you understand how parsing works to apply it to your business case in the most efficient way.
