Being a dedicated JSON file viewer software, it displays numerous information of a JSON file in it. When you open this freeware, you will get a blank interface with only one option that is File from where you can browse and open a small or large JSON file. Once a JSON file is loaded, the interface shows information in two different sections. Download JSON Viewer for Windows now from Softonic: 100% safe and virus free.

Since many different programs may use JSON files for different purposes, you may need to try a few of the apps to open your specific JSON file. JavaScript Object Notation (JSON) is a format used to store structured data in JavaScript derived data format. JSON was designed by Douglas Crockford while his work in State Software. JSON at that time was designed to exchange application state information between web application and back-end server.

JSON is a data format that is common in configuration files like package.json or project.json. We also use it extensively in Visual Studio Code for our configuration files. When opening a file that ends with .json, VS Code provides features to make it simpler to write or modify the file's content.

IntelliSense and validation

For properties and values, both for JSON data with or without a schema, we offer up suggestions as you type with IntelliSense. You can also manually see suggestions with the Trigger Suggestions command (⌃Space (Windows, Linux Ctrl+Space)). We also perform structural and value verification based on an associated JSON schema giving you red squiggles.

Package and project dependencies

We also offer IntelliSense for specific value sets such as package and project dependencies in package.json, project.json, and bower.json.

Quick navigation

JSON files can get large and we support quick navigation to properties using the Go to Symbol command (⇧⌘O (Windows, Linux Ctrl+Shift+O)).

Hovers

When you hover over properties and values for JSON data with or without schema, we will provide additional context.

Formatting

You can format your JSON document using ⇧⌥F (Windows Shift+Alt+F, Linux Ctrl+Shift+I) or Format Document from the context menu.

Folding

You can fold regions of source code using the folding icons on the gutter between line numbers and line start. Folding regions are available for all object and array elements.

JSON with Comments

In addition to the default JSON mode following the JSON specification, VS Code also has a JSON with Comments (jsonc) mode. This mode is used for the VS Code configuration files such as settings.json, tasks.json, or launch.json. When in the JSON with Comments mode, you can use single line (//) as well as block comments (/* */) as used in JavaScript. The current editor mode is indicated in the editor's Status Bar. Click on the mode indicator to change the mode and to configure how file names and extensions are associated to modes.

JSON schemas and settings

To understand the structure of JSON files, we use JSON schemas. JSON schemas describe the shape of the JSON file, as well as value sets, default values, and descriptions. The JSON support shipped with VS Code supports JSON Schema Draft 7.

Servers like JSON Schema Store provide schemas for most of the common JSON-based configuration files. However, schemas can also be defined in a file in the VS Code workspace, as well as the VS Code settings files.

The association of a JSON file to a schema can be done either in the JSON file itself using the $schema attribute, or in the User or Workspace settings (File > Preferences > Settings) under the property json.schemas.

VS Code extensions can also define schemas and schema mapping. That's why VS Code already knows about the schema of some well-known JSON files such as package.json, bower.json, and tsconfig.json.

Mapping in the JSON

In the following example, the JSON file specifies that its contents follow the CoffeeLint schema.

Note that this syntax is VS Code-specific and not part of the JSON Schema specification. Adding the $schema key changes the JSON itself, which systems consuming the JSON might not expect, for example, schema validation might fail. If this is the case, you can use one of the other mapping methods.

Mapping in the User Settings

The following excerpt from User Settings shows how .babelrc files are mapped to the babelrc schema located on https://json.schemastore.org/babelrc.

Tip: In addition to defining a schema for .babelrc, also make sure that .babelrc is associated to the JSON language mode. This is also done in the settings using the files.association array setting.

Mapping to a schema in the workspace

To map a schema that is located in the workspace, use a relative path. In this example, a file in the workspace root called myschema.json will be used as the schema for all files ending with .foo.json.

Mapping to a schema defined in settings

To map a schema that is defined in the User or Workspace settings, use the schema property. In this example, a schema is defined that will be used for all files named .myconfig.

Mapping a schema in an extension

Schemas and schema associations can also be defined by an extension. Check out the jsonValidation contribution point.

File match syntax

The file match syntax supports the '*' wildcard. Also, you can define exclusion patterns, starting with '!'. For an association to match, at least one pattern needs to match and the last matching pattern must not be an exclusion pattern.

Define snippets in JSON schemas

JSON schemas describe the shape of the JSON file, as well as value sets and default values, which are used by the JSON language support to provide completion proposals. If you are a schema author and want to provide even more customized completion proposals, you can also specify snippets in the schema.

The following example shows a schema for a key binding settings file defining a snippet:

This is an example in a JSON schema:

Use the property defaultSnippets to specify any number of snippets for the given JSON object.

• label and description will be shown in the completion selection dialog. If no label is provided, a stringified object representation of the snippet will be shown as label instead.
• body is the JSON object that is stringified and inserted when the completion is selected by the user. Snippet syntax can be used inside strings literals to define tabstops, placeholders, and variables. If a string starts with ^, the string content will be inserted as-is, not stringified. You can use this to specify snippets for numbers and booleans.

Note that defaultSnippets is not part of the JSON schema specification but a VS Code-specific schema extension.

Offline mode

json.schemaDownload.enable controls whether the JSON extension fetches JSON schemas from http and https.

A warning triangle will show in the status bar when the current editor would like to use schemas that can not be downloaded.

Json Formatter Online

JavaScript Object Notation (JSON) is a format used to store structured data in JavaScript derived data format. JSON was designed by Douglas Crockford while his work in State Software. JSON at that time was designed to exchange application state information between web application and back-end server.

At this time there are multiple ways how JSON files are used. This includes:

• Configuration files. Many server-based JavaScript applications like node.js, reactJS and others use JSON files to store configuration information.
• Data storage. NoSQL database engines like MongoDB use JSON to store structured data in the database.
• Application state and notifications. Web applications use JSON to deliver notifications to a server or to download web application state.

JSON is a plain text file format. It also has a fairly straightforward format which could be interpreted by a human if JSON file is opened in a text editor. For example, JSON configuration files could be easily modified and saved back without use of a special software. So, if you have a JSON file which is a configuration file for one of your applications, you can try changing it. When doing this make sure that you don’t break formatting of the JSON file since any error in formatting will cause an application to fail during JSON file loading.

It is still recommended to use an application which produced JSON file to edit it, since there could be a certain formatting in JSON which application expects. For example, certain PC games store settings in JSON file. Typically, these settings could be changed inside the game, but sometimes game developers also provide a tool which can edit settings and save them in the correct format.

JSON files are transferred in e-mail and via internet network connections using application/json mime type. Since JSON is a plain text format with many repeating words and/or numbers it is easily compressible by popular compression algorithms.
