JSON File Extension  What is .Json and how to open them? ▷ 2020

Programming is one of the elemental forces of computing. If in the real world we say that water is the basis of all existing life, the programming would be the equivalent to this in the virtual world. This is the basis for all programs, browsers and other drivers.

Among the many languages ​​that exist, the JSON format It is one of the most used due to its relationship with Java, one of the most important languages ​​in the world. Many people ignore it, but the importance of this in the generation of webs and other programs is important.

In this article we are going to show you what JSON files are and how they work, as well as we will also present a series of processes that you can apply to open them and visualize the interior of them.

What is .JSON files and what are they used for?

files with .JSON extension

The .JSON format is one of the many simple texts used for data exchange. This was born as a subset of JavaScript, but its versatility made it be considered an independent language for its usefulness as an alternative to the classic XML.

Among the facilities it has in relation to this, is the fact that with JSON it is much easier to write a parser, in addition to being very easy to analyze any file with this language.

However, programming in this format is slightly more expensive than in most languages, which is why its use occurs especially in systems where massive data transmission is of vital importance, such as search engines such as Google or Yahoo!

Further, In most cases, just programming in JSON is not enough, but needs to be combined with XML for better performance.

Beyond this, the most widely used ecosystem for JSON files is web applications or APIs that run online and require clean and smooth data transmission. Currently there are multiple APIs that have support to understand this language independently.

How to open and read .JSON files?

To open and read a JSON file you will need a text engine that can identify the codes written within it. There are many such programs, but the most popular are Python, Excel, Javascript and some online platforms.

Next we are going to show you how to do it in each of them in the simplest way possible:

In python

Python is one of the most used programs in the world of programming. It works similar to the classic Windows Notes Blog, but It has a series of functions and automatable commands that make the task of programming much easier. In this you can both read and write JSON files with ease.

If what you want is to read a file in this language, what you should do is the following:

  • You must open the program and follow the path “File”> “Open”.
  • You must find the file you want to read and open it and then apply the command “json.load”.
  • Once this is done you will see in the Python terminal all the codes contained in the chosen JSON file.

In excel

Yes, this is just a spreadsheet, but it doesn’t mean that it can’t read programming formats. Excel is undoubtedly one of the most versatile software in the Office suite. This, among the many functions it offers, gives you the ability to easily read a JSON file to appreciate the content inside.

What you should do for this is the following:

  • Obviously you must open Excel in the conventional way and position yourself in a new spreadsheet.
  • When doing this and being on the blank page, the next thing you have to do is go to the tab “Data” and follow the route “Get data”> “From file “>”From JSON “.
  • After this you will have to navigate through the folders until you reach the specific location of the file you want to read and click on “Open”. After these steps you should see all the text contained in the JSON file.


Being such a popular program, a wide variety of virtual tools have spread on the internet that are capable of editing and opening JSON files without any problem. In this sense, you can find many, but in this case we will teach you how to do it using Jsoneditoronline.org, an excellent online application that can help you with this task.

What you should do is the following:

  • Go to the web jsoneditoronline.org.
  • Now go to the tab “Open” and click “Open from disk”.
  • Now you just have to locate the Json file you want to open and voila, its content will be shown to you in the main interface of the application.

Read with Javascript

JavaScript is a programming technology that is staying in the past, but there are still several portals that use it. It should be noted that Javascript is not a software, but a programming language, so you will have to use different codes to get where you want, which requires a certain level of moderately advanced knowledge to understand the following process.

JSON files

What you have to do to read a JSON file is use the JQuery library. What you should do is use the “Lee_json ()“and identify the file among all those that can make up your website or web tool to see the content inside.

In short, the easiest solution is to put the .json next to the .html and call it like this:

*Note: for this code to work you must change the symbol “for normal quotes.

It is a fairly simple process but it can be disorienting for users with little knowledge of the Javascript ecosystem.
