Sublime Json Formatter: Json Explained

Table of Contents

JSON (JavaScript Object Notation) is a way to store and represent data in a human readable format. It is often used when working with complex data that needs to be shared and manipulated by different systems. It can also be used to easily create APIs that can be consumed by other applications. In order to get the most out of JSON, you’ll need a formatting tool, especially when working with large files. Sublime is a powerful text editor with a built-in Json Formatter. This article will discuss what JSON is, why a formatter is useful, different types of Json formatting, benefits of using Sublime for Json formatting, best practices for Json formatting, how to install Sublime Json Formatter, and troubleshooting common issues with Json formatting.

What is Json?

JSON is a popular data-interchange format used for transmitting data between servers and web applications. It is based on a subset of the JavaScript programming language, and was originally developed as a way to store and share structured data between applications. It is lightweight, easy to use, and works well with both web and mobile applications.

JSON is structured around key-value pairs, where the key is always a string and the value can be a string, number, object, array, or boolean. For example, if you have data about an object such as a book, you could represent it in JSON as:

{  "title": "The Lord of the Rings",  "author": "J.R.R. Tolkien",  "pages": 437}

JSON is used for transferring data between web applications, as an alternative to more traditional methods such as XML. It is simpler to use than XML and often more efficient in terms of both size and speed, making it an ideal choice for many applications.

JSON is also used for data serialization, which is the process of converting data into a format that can be easily stored and transferred. This makes it a great choice for applications that need to store and transfer large amounts of data, such as databases and web services.

Why Use a Json Formatter?

JSON can be difficult to read when it’s written in its raw form. Using a Json Formatter allows developers to take large amounts of unformatted or poorly formatted JSON and convert it into a readable, organized format. This makes it easier for developers to debug their code and quickly identify errors or potential problems.

JSON Formatters also allow developers to more easily modify the data stored in their JSON files by providing an environment that makes it easier to inspect and edit JSON snippets. Furthermore, Formatters allow developers to quickly validate their JSON files and ensure that they are syntactically valid before deploying their code.

Using a JSON Formatter can also help developers to quickly identify any potential security issues with their code. By providing a visual representation of the data stored in the JSON file, developers can quickly spot any potential vulnerabilities and take steps to address them.

Different Types of Json Formatting

There are several different types of JSON formatting options available, depending on the needs of the user. Popular formats include pretty-printing JSON, minifying JSON, and validating JSON.

Pretty-printing JSON simply means making it more human-readable by introducing additional whitespace and indentation to make it easier to read. Minifying JSON structures strips out unnecessary whitespace to make the file size smaller. Lastly, validating JSON ensures that the file conforms to the syntax rules defined by JSON schema.

In addition to the popular formatting options, there are also tools available to help users convert JSON data into other formats, such as XML or CSV. This can be useful for applications that require data to be in a specific format, or for data analysis and visualization.

Benefits of Using Sublime for Json Formatting

Sublime is a popular text editor renowned for its extensibility and customizability. The Sublime Text Json Formatter plugin makes it easy for developers to format their JSON code in an elegant fashion. It contains features such as syntax highlighting, column guides, auto-complete suggestions, undo/redo capability, and an assortment of formatting options.

In addition, Sublime provides many other powerful features that make it ideal for JSON developers. It supports over 50 programming languages, including JavaScript, so developers can use Sublime to work with multiple types of files. It also has a powerful search and replace feature which allows developers to quickly find and modify specific parts of their code.

Sublime also offers a wide range of customization options, allowing developers to tailor the text editor to their specific needs. It has a built-in package manager that makes it easy to install and manage plugins, and it also supports multiple themes and color schemes. With these features, developers can create a unique and personalized coding environment that suits their individual preferences.

Best Practices for Json Formatting

When formatting JSON files with a text editor such as Sublime, there are a few best practices that developers should keep in mind:

  • Use valid JSON syntax
  • Be mindful of potential performance issues
  • Avoid unnecessary whitespace
  • Document your work clearly
  • Test your code frequently

These best practices will help developers create well-structured JSON code that is easy to read, maintain, and debug.

It is also important to use a linter to check for errors in your code. A linter can help you identify any potential issues with your code before you deploy it. Additionally, using a version control system such as Git can help you keep track of changes to your code and ensure that you have a backup of your work.

How to Install Sublime Json Formatter

Sublime Json Formatter can be easily installed through the Package Control panel in Sublime Text. To do so:

  • Open the Package Control panel by pressing Ctrl+Shift+P or Cmd+Shift+P on Mac.
  • Type “Install Package” and select “Package Control: Install Package” from the list of options.
  • Type “Json Formatter” into the search box.
  • Select “Json Formatter” from the list of options.
  • Once installed, press Ctrl+Shift+F or Cmd+Shift+F on Mac to open the Sublime Json Formatter window.

Once the Sublime Json Formatter window is open, you can format your JSON code by pressing the “Format” button. You can also customize the formatting options by clicking the “Options” button. After you have finished formatting your code, you can save it by pressing the “Save” button.

Troubleshooting Common Issues with Json Formatting

When working with JSON code, there are certain errors that can occur and lead to unexpected results. Common errors include syntax errors caused by missing commas or brackets, duplicate keys, invalid data types and values, and unexpected characters. To troubleshoot these types of errors in Sublime Text:

  • Open the Sublime Json Formatter window by pressing Ctrl+Shift+F or Cmd+Shift+F on Mac.
  • Check the box labeled “Syntax Checker” to enable syntax checking functionality.
  • Fix any errors that are reported by the syntax checker.
  • If no errors are reported but unexpected behavior is still occurring in your code, double check the validity of your data types and values.


Sublime Text’s Json Formatter plugin is a powerful tool that makes it easy for developers to format, validate, and debug their JSON code. It contains features such as syntax highlighting, auto-complete suggestions, column guides and undo/redo capability. By following the best practices outlined in this article, developers can easily create valid and efficiently formatted JSON code.
