Json Formatter Notepad++: Json Explained

Table of Contents

JSON, which stands for JavaScript Object Notation, is a common format used for data interchange on the internet. It’s widely used in modern web technologies and is also commonly used for configuration files, databases, and web services. JSON Formatter Notepad++ is a plugin for the Notepad++ text editor used to properly format and edit JSON documents. It automatically checks input code for errors and helps with syntax highlighting, auto-completion, and indentation.

What is Json?

JSON is a lightweight, language-independent data exchange format that provides a human-readable syntax for representing structured data. It is based on a subset of the JavaScript programming language and has become the industry standard for transmitting and serializing structured data over the web. Compared to XML, which is another popular data structure format, JSON is much less verbose and requires fewer characters to keep the same amount of data. JSON object syntax closely resembles object literal notation in JavaScript, making it easy to parse and utilize in applications.

JSON is often used in web applications to send data from the server to the client. It is also used in mobile applications to store and retrieve data from a local database. Additionally, JSON is often used to exchange data between different programming languages, such as JavaScript and Python. It is also used to store configuration settings and other data in a structured format.

Why Use Json Formatter Notepad++?

For many users, the native JSON support in Notepad++ is often not enough to make working with it an efficient and hassle-free experience. Json Formatter Notepad++ takes already existing tools in the Notepad++ text editor and makes them more powerful when dealing with JSON. It helps significantly reduce the time it takes to manually check for errors, auto-complete elements, re-indent code, or quickly view data in a more readable way.

Json Formatter Notepad++ also provides a range of features that make it easier to work with JSON data. For example, it can automatically detect and highlight syntax errors, as well as provide a range of formatting options to make the data easier to read. Additionally, it can also provide a range of tools to help you quickly search and filter through large amounts of data.

Benefits of Using Json Formatter Notepad++

Some benefits of using the Json Formatter Notepad++ plugin are:

  • JSON Syntax Highlighting: Text and code are color coded to make it easier to distinguish elements within the code.
  • Error Checking: The plugin automatically checks input code for errors such as missing quotes and parentheses.
  • Auto-Complete Elements: Automatically populate elements with data from your JSON documents.
  • Formatting and Indentation: Automatically re-indent your code so it’s easier to read.
  • Quick View: When hovering over an element, the plugin displays its value or data.
  • Duplicate Key Finder: Identifies any duplicate keys in your JSON code.

The Json Formatter Notepad++ plugin also allows you to easily copy and paste JSON code from other sources, making it easier to work with multiple documents at once. Additionally, the plugin is free to download and use, making it a great choice for developers of all skill levels.

Working With Json in Notepad++

Once you have completed the setup process, you are now ready to start working on JSON documents in Notepad++. To get familiar with the different features this plugin has to offer, open a JSON document and experiment with different operations such as syntax highlighting, auto-completion, formatting, quick view, and duplicate key finder.

You can also use the plugin to validate your JSON documents. This is especially useful if you are working with large documents and need to ensure that the syntax is correct. Additionally, you can use the plugin to convert JSON documents to other formats such as XML, YAML, and CSV.

Editing and Formatting Json with Notepad++

Json Formatter Notepad++ makes it easier to edit structured content from within your text editor. You can quickly insert key-value pairs and restructured elements such as arrays and objects using indention-sensitive auto-completion. It also provides helpful formatting tools such as auto indentation and formatting. Additionally, you can display element values and data when hovering over elements which makes debugging much easier.

Notepad++ also offers a wide range of features to help you work with Json files. You can easily search and replace text, as well as use the built-in syntax highlighting to quickly identify errors. Additionally, you can use the built-in linting feature to check for any syntax errors in your code. This makes it easier to spot and fix any issues before they become a problem.

Troubleshooting Common Issues With Json Formatter Notepad++

If you are having trouble getting the plugin to run properly within Notepad++, make sure you have updated to the latest version of not just the plugin, but also Notepad++ itself.

Also, open the “Plugins > Json Formatter > Set Preference” menu again to ensure you have configured everything correctly.

Tips for More Effective Use of Json Formatter Notepad++

  • Before making any major changes to your code, always save a backup of your original file.
  • When making changes, use plugins such as “Compare” or “Figure Out” to verify whether your changes are correct.
  • Keep your code organized by following proper indentation guidelines. This can save you time in the long run.
  • Use auto-complete to quickly populate elements without having to manually type out values.
  • When debugging more complex documents, use breakpoints to pinpoint difficult segments of code.


JSON has become a widely used format for many types of applications and services, making it essential for developers to know how to work with it efficiently.
