JavaScript Object Notation (JSON) is a standard, popular and lightweight data text-oriented format based on JavaScript object syntax to represent structured data. You can use JSON independently of JavaScript, but it strongly resembles JavaScript object literal syntax, and several programming environments can interpret (parse) and create JSON.
JSON is often adopted in web services and APIs — enabling web applications to transfer and retrieve data with a common format. JSON can be used with many modern programming languages. JSON is considered one of the popular, easiest, and lightweight and formats used for interaction between services.
JSON has attracted the attention of tool builders, who have created a variety of tools for reformatting, validating, and parsing JSON.
Here’s our verdict captured in a legendary LinuxLinks-style ratings chart. They are all free and open source goodness.
Let’s explore the 14 JSON tools. For each title we have compiled its own portal page, a full description with an in-depth analysis of its features, together with links to relevant resources.
