JSON (JavaScript Object Notation) is defined as a file format used in object-oriented programming that uses human-readable language, text, and syntax to store and communicate data objects between applications. JSON is used in electronic data exchange, such as transmitting data in web applications.
As applications get more complex, the requirement to properly extract and alter data within JSON documents increases. This is where JSONPath, a JSON-specific query language, is useful. Developers use a JSONPath tester to develop and validate JSONPath expressions. This tool allows users to validate their queries against a JSON document, verifying that they are correctly written and produce the intended results.
Let’s learn about the JSONPath tester in detail.
