If you’re using WordPress to host your own content, then you’ll likely want to use JSON for your data files. JSON is a lightweight data format that’s popular with developers and makes it easy to upload JSON files to WordPress and manage your JSON content.
A wealth of knowledge is available on the web about JSON, and it’s a topic that gets some significant attention among developers. Even as I write this article, I get emails from people who’ve heard of JSON but don’t know what it is. And while there are many blog posts, articles, and tutorials on the topic, there is very little that goes into the natty gritty of how to actually format a JSON file for WordPress.

How to Upload JSON File to WordPress
Uploading JSON files to WordPress can be a daunting task, but with a few simple steps, it’s easy to get your content up and running. In this guide, we’ll show you how to upload JSON files to WordPress site.
A Brief History of JSON
A) It’s not XML, which is another data format. Another reason why other people should avoid using JSON.
B) The json_encode() function can only be used on strings (which makes sense given that they contain numbers).
C)You can store anything in it. The only things that are not legal are arrays and objects (which are still legal), but there are no rules against those either.
D) There’s no defined number of characters for each datatype, so any string with more than 255 characters will not be valid. However, most programs will return a valid string if you type “1” at the command line or pass it as an argument to an application; just make sure you don’t pass it an integer value greater than its length.
E) When creating JSON, you can use one of two forms: new object [array] or new array [object].Or you can even use an empty array directly as a single item in the serialized JSON object, but this is usually best avoided since it results in a fairly useless string (I don’t know why this happens).
F) Many array and object manipulation operators are available, including indexOf(), lastIndexOf(), min(), max(), random(), getItem(), setItem(value), and setValue(value). All these functions accept an optional second parameter which specifies what sort of operation to perform on the first parameter—you can also combine multiple operations into one call if you like—and return either a boolean or a corresponding value depending on what was applied. To find out more about these functions, see here.
G) Other string manipulation functions include split(), join(), splitWith(), joinWith(), length(), trim(), filter(), contains, prepend, substr(), insertNewlineAfter, insertTrimAtEnd, and trimNewlineBefore. This list is far from complete, though I doubt there will ever be any special operators added that aren’t already supported by JavaScript’s built-in operators!
What is JSON format?
JSON (JavaScript Object Notation) is a data format used for transmitting data in web applications. JSON was designed to be human-readable, which makes it ideal for transferring data between a server and a client. In addition, JSON is lightweight and can be sent over HTTP networks without affecting performance. JSON data is easy to read and write, making it ideal for transmitting data between the server and client.
JSON is a standard text-based format for representing structured data. It is most commonly used in web development, but can be used in any scenario where data needs to be exchanged between programs. JSON was designed as a replacement for XML, which was originally designed as a markup language for describing the structure of documents.
There are two main types of JSON: compact and tall. Compact JSON is shorter and easier to read, while tall JSON is more verbose and allows for more complex structures.
Here is an example of JSON data:
JSON Strings & Numbers
The problem with WordPress JSON strings is that you can’t use them directly in your code. You must use the JavaScript function wp_parse_json() .
To upload JSON files to WordPress, you need to use some special characters, including spaces and colons (“:”). You can also use curly brackets (“{ } ”) as well as arbitrary arrays.
Use the following form when uploading JSON files:
The following form will upload any number of JSON files to WordPress:

Why do you need a json file for WordPress?
It’s easy to read and write, making it perfect for building applications with PHP, MySQL and JavaScript. JSON files are also valid HTML documents, so you can use them to create dynamic websites.
It is efficient for data exchanges between web applications and back-end systems. JSON supports objects, arrays, strings, numbers, and Booleans. It also has a built-in key/value storage mechanism. Because JSON is lightweight and efficient, it can be used to build small applications or as part of a larger application architecture.

You need to put the code in the theme’s function.php. Follow the instructions carefully.
Step 1:
Log in to your WordPress dashboard.
Then go to Appearance >> Themes File Editor.
Step 2:

By Edit wp-config.php:
On the basis of some demand, Super Admins can be given the capability to be special cases.
