16 Best JSON viewer Tools Compared for Developers

Introduction

Do you know the number of active websites on the Internet?

Yes, you guessed it right. The number is 1 billion!

And what’s the percentage of them using JSON?

Well, 21.6% use JSON!

It means, a lot of data travels through JSON.

While JSON format is truly wonderful, the question is how to read JSON files?

To use JSON and get some data, all you need to do is get hold of a JSON viewer.

Fortunately, there are quite a few free online JSON viewers that you can use. You can paste the JSON code and visualize the data.

In this sense, JSON viewer is an integral part of a developer’s toolkit!

Before we dive right into JSON viewer tools and their comparison, let’s try and understand JSON and JSON viewer.

What is JSON?

JSON is an abbreviation of JavaScript Object Notation.

JSON is merely the syntax for storing and exchanging data.

It is particularly useful because it is easy for humans to read and write. At the same time, machines also find it easy to parse and generate.

JSON is arguably the most effective tool if you want to share data of any size, including even audio, video etc.

It has the wide range of supported browser compatibility with the operating systems so the applications made with the coding of JSON don’t require much effort to make it all browsers compatible.

JSON Format Example: The following example illustrates a possible JSON representation describing a person.

{
 "firstName": "John",
 "lastName": "Smith",
 "isAlive": true,
 "age": 27,
 "address": [
  "streetAddress": "21 2nd Street",
  "city": "New York",
  "state": "NY",
  "postalCode": "10021-3100"
},
 "phoneNumbers": [
 {
  "type": "home",
  "number": "212 555-1234"
 },
 {
  "type": "office",
  "number": "646 555-4567"
 },
 {
  "type": "mobile",
  "number": "123 456-7890"
 }
],
 "children": [],
 "spouse": null
}

What is JSON viewer?

JSON Viewer is a tool that will let you view and debug JSON documents. You can utilize these JSON file viewer tools to view as well as edit a JSON file.

Some of these also offer dual-mode view which is Tree mode and Text mode to view a JSON.

The first one can help you use the former mode to view JSON file in a Tree-based hierarchy. The second one will allow you to view the text data which you can edit and save as well.

A lot of these JSON viewers display information of JSON file in a way that makes it really easy to understand, even for someone who does not have a developer background or skills.

Some of these tools can help you out with respect to formatting a JSON file or string.
