How to convert json string to string

JSON to String Converter

JSON is an extended Programming language from JavaScript/ECMAScript and it’s an «open standard file and data interchange format». It is a common data format with distinct uses in electronic data interchange, and also used in Web Applications with servers. This JSON acronym arrive from “JavaScript Object Notation”

And JSON language is an independent data intersection format and its text-based lightweight programming accent. JSON gave specific and uncomplicated notations to express the objects, collections of name/value duos, arrays, and an ordered list of values.

The use of JSON independence language is to transmit data or info in Web Applications and a simple step to clarify this work is to “Sending some data from the server to the client and vice versa and that transmitted data will be displayed on the web page.

JSON file stockpile or store the simple data structures and objects in JavaScript Object Notation(JSON) format. We can open this JSON file in any normal text editor but different Operating Systems (OS) like Windows, Linux, and macOS use a variety of tools to open the JSON file. And these tools are open-source software so we don’t need to pay anything while we use these tools.

JSON Schema is a grammar language used to stipulate the structure, content, and semantics of JSON objects. And it exemplifies the metadata(data about data) with this «What an object’s properties mean» and another one is what value is valid for those properties. The JSON programming language also includes some set of the list or (list of item) it is surrounded with Square Brackets([]) and its name is «JSON Array».

Additionally, we don’t have any restrictions on the length of the content you need to convert. Our major goal is to make your editing process simple and effective without taking much of your time.

Why do you need to check our JSON to String Converter?

Our JSON to String Converter tool is responsible for extracting all the string values from the JSON which means JavaScript Object Notation file. Thus, the tool ignores all the characters from the JSON and thereby leaving the Strings and Numbers in the file.

Moreover, you don’t need to worry about the quality and accuracy of the outcome you look for. As we have adopted advanced technologies to implement this, we make the process of conversion completely effective.

How to Convert JSON to String?

To convert your text from JSON file to String, here are the following steps you should perform:

Example Explanation:

To give you a clear perception, let me explain with an example:

This is the content from JSON File which should be converted to String:

JSON.stringify()

The JSON.stringify() method converts a JavaScript object or value to a JSON string, optionally replacing values if a replacer function is specified or optionally including only the specified properties if a replacer array is specified.

Try it

Syntax

Parameters

The value to convert to a JSON string.

A function that alters the behavior of the stringification process, or an array of strings or numbers naming properties of value that should be included in the output. If replacer is null or not provided, all properties of the object are included in the resulting JSON string.

A String or Number object that’s used to insert white space (including indentation, line break characters, etc.) into the output JSON string for readability purposes.

If this parameter is not provided (or is null ), no white space is used.

Return value

A JSON string representing the given value, or undefined.

Exceptions

Description

JSON.stringify() converts a value to JSON notation representing it:

Examples

Using JSON.stringify

The replacer parameter

The replacer parameter can be either a function or an array.

As a function, it takes two parameters: the key and the value being stringified. The object in which the key was found is provided as the replacer ‘s this parameter.

Initially, the replacer function is called with an empty string as key representing the object being stringified. It is then called for each property on the object or array being stringified.

It should return the value that should be added to the JSON string, as follows:

Note: You cannot use the replacer function to remove values from an array. If you return undefined or a function then null is used instead.

Note: If you wish the replacer to distinguish an initial object from a key with an empty string property (since both would give the empty string as key and potentially an object as value), you will have to keep track of the iteration count (if it is beyond the first iteration, it is a genuine empty string key).

Example replacer, as a function

Example replacer, as an array

If replacer is an array, the array’s values indicate the names of the properties in the object that should be included in the resulting JSON string.

The space argument

The space argument may be used to control spacing in the final string.

Using a tab character mimics standard pretty-print appearance:

toJSON() behavior

If an object being stringified has a property named toJSON whose value is a function, then the toJSON() method customizes JSON stringification behavior: instead of the object being serialized, the value returned by the toJSON() method when called will be serialized. JSON.stringify() calls toJSON with one parameter:

Issue with JSON.stringify() when serializing circular references

Note that since the JSON format doesn’t support object references (although an IETF draft exists), a TypeError will be thrown if one attempts to encode an object with circular references.

To serialize circular references you can use a library that supports them (e.g. cycle.js by Douglas Crockford) or implement a solution by yourself, which will require finding and replacing (or removing) the cyclic references by serializable values.

Issue with plain JSON.stringify for use as JavaScript

A common use of JSON is to exchange data to/from a web server.

When sending data to a web server, the data has to be a string.

Stringify a JavaScript Object

Imagine we have this object in JavaScript:

Use the JavaScript function JSON.stringify() to convert it into a string.

The result will be a string following the JSON notation.

myJSON is now a string, and ready to be sent to a server:

Example

You will learn how to send JSON to a server in the next chapters.

Stringify a JavaScript Array

It is also possible to stringify JavaScript arrays:

Imagine we have this array in JavaScript:

Use the JavaScript function JSON.stringify() to convert it into a string.

The result will be a string following the JSON notation.

myJSON is now a string, and ready to be sent to a server:

Example

You will learn how to send a JSON string to a server in the next chapters.

Storing Data

When storing data, the data has to be a certain format, and regardless of where you choose to store it, text is always one of the legal formats.

JSON makes it possible to store JavaScript objects as text.

Example

Storing data in local storage

// Storing data:
const myObj = ;
const myJSON = JSON.stringify(myObj);
localStorage.setItem(«testJSON», myJSON);

// Retrieving data:
let text = localStorage.getItem(«testJSON»);
let obj = JSON.parse(text);
document.getElementById(«demo»).innerHTML = obj.name;

Exceptions

Stringify Dates

In JSON, date objects are not allowed. The JSON.stringify() function will convert any dates into strings.

Example

You can convert the string back into a date object at the receiver.

Stringify Functions

In JSON, functions are not allowed as object values.

The JSON.stringify() function will remove any functions from a JavaScript object, both the key and the value:

Example

This can be omitted if you convert your functions into strings before running the JSON.stringify() function.

Example

If you send functions using JSON, the functions will lose their scope, and the receiver would have to use eval() to convert them back into functions.

How to Convert Javascript JSON to String

JSON is a common datatype to exchange the data from the client and server. When we want to send data from the client to a web server, the data must be a string.

Javascript JSON to String

To convert a JavaScript object to string, use the JSON.stringify() function. The JSON.stringify() method converts JavaScript object into string.

Let’s stringify the Javascript Object.

Output

You can see that myJSON will be a string following the JSON notation.

In JSON, functions are not allowed as object values. The JSON.stringify() function removes any functions from a JavaScript object, both the key and the value.

Output

You can see that the function is removed from the myJSON string.

Parsing JSON

Parsing the json data in Javascript means converting json data to an object. JSON.parse() method is an inbuilt JavaScript method that converts text into a JavaScript object.

JavaScript functions are not allowed in JSON. If you want to include a function, write it as a string.

Output

The output here is a js object.

That is it for Converting Javascript json to string.

How to Convert String to JSON and Vice Versa

In this tutorial, we will learn about How to Convert String to JSON and Vice Versa. First things first, What is JSON?

JSON is an acronym for JavaScript Object Notation. It is lightweight data transferring format among different web services. Mostly it is used to build an API.

Example of a JSON

This is an example of JSON it stores data in key-value format and values can be the array of another primitive datatype or another JSON.

There are three methods to convert JSON to String and Vice Versa in Java

Using JSON Library

Using Gson Library

Using Jackson Library

While running a program where these libraries are included we need to download these jar files and add them inside the project according to IDE otherwise functions from these libraries will not support and cause an error. You can refer following links to download these libraries

Let’s look one by one with the help of examples.

Example JSON Library

In the code given below, we have a JSON data stored in the form of String. Converting a string JSON is very much convenient to perform multiple actions. JSONObject is a class of org.json package that converts a string to an JSON object.

Example JSON Library : JSON to String

In the above code, we learned how to convert a string to a JSON object and now we can go for JSON object to a string we will learn creating an object from scratch also. Firstly we will create a JSON object and add values this class has JSONObject.put() method which accepts two parameter key and value.

Example GSON Library

Whatever the two things we did in the above code block we will do the same stuff using the Gson library. This library is developed by Google and widely used in the industry. JsonParser is a class that is responsible to parse a string and parse() is a method that accepts a string. Finally, we use getAsJsonObject() to get all the above conversion in JsonObject format.

Example GSON Library : JSON to String

Example Jackson Library

Jackson is a library that provides a lot of flexibility while working with JSON. We need to create a mapper from ObjectMapper class then we create a JsonFactory class object from a mapper and call that mapper to create a parser and finally this parse will create actually JSON object for us using readTree() method. readTree() will accept the parser object and trace the hierarchy of JSON.

Example Jackson Library : JSON to String

To create String from Json object Jackson library provides writeValueAsString() method in ObjectMapper class. This value accepts JSON objects and returns the string.
