What is JSON (JavaScript Object Notation)?​

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, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language-independent but uses conventions that are familiar to programmers of the C family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others. These properties make JSON an ideal data-interchange language.

What are the use cases of JSON?​

  1. Data exchange: JSON is often used to transmit data between a server and a web application, or between different parts of a web application.
  2. Configuration files: JSON is sometimes used as a configuration file format, especially for web applications.
  3. NoSQL databases: Some NoSQL databases, such as MongoDB, use JSON documents to store data.
  4. RESTful APIs: JSON is often used as a format for sending and receiving data in web services, especially in RESTful APIs.
  5. Microservices: JSON is a popular data-interchange format for microservices architecture, as it is lightweight and easy to parse.

JSON is also used in various other applications such as log files, message queues, and various other data storage and transmission formats.

What is JSON Formatter?​

A JSON Formatter is a tool that takes a JSON string and checks the integrity/syntax of the JSON data based on JavaScript Object Notation (JSON) Data Interchange Format Specifications (RFC) and formats it in a way that is more human-readable. This typically includes adding indentations and line breaks to make the structure of the JSON data more clear.

What are the features of JSON Formatter?​

  1. Validation: Validate the JSON data and display the error messages if any.
  2. Syntax Highlighting: Easier to identify different elements of the JSON data, such as keys, strings, and numbers.
  3. Indentation: See the hierarchical structure of the JSON data.
  4. Collapsible Nodes: Users can hide or show parts of the JSON data as needed.
  5. Edit Nodes: Change the value of the Key-Value pair.
  6. Add Nodes: Update the JSON with new Nodes.
  7. Delete Nodes: Remove unwanted Nodes.
  8. Load the Editor with the sample JSON data.
  9. User can copy the JSON data to Clipboard.
  10. Once created or modified, JSON files can be downloaded and opened in alternative text editors such as Notepad++, Sublime, or VSCode.
  11. User can print the JSON data.
  12. As JSON is commonly used in API data transfer, this tool can also be utilized as an API formatter.
