What is JSON?

      

        JSON (JavaScript Object Notation) is a lightweight data-interchange format
        that is easy for humans to read and write, and easy for machines to
        parse and generate. It is based on a subset of the JavaScript
        programming language and uses a simple text format to represent
        structured data as objects and arrays. Because of its simplicity and
        language‑agnostic design, JSON has become the de‑facto standard for
        exchanging data between web clients and servers, mobile apps, cloud
        services and databases.
      

      
Why format and convert JSON?

      

        Raw JSON is often minified – all whitespace is removed to save
        bandwidth. While this makes it compact for transmission, it can be
        difficult to read and debug. Formatting JSON adds indentation and
        line breaks so you can quickly understand the structure of your data.
        Converting JSON to other formats like XML, CSV or YAML allows you to
        integrate with systems that expect those formats or to analyse and
        present your data in different ways. Our tool performs all of these
        tasks entirely in your browser, ensuring your information stays
        private.
