Confused about .json() vs .text() (Example) (2024)

FAQs

What is the difference between text and JSON? ›

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.

In that case, the difference is that ". text()" will give you the result in string format, and ". json()" will parse it from JSON and convert it into an object.

Response: json() method

It returns a promise which resolves with the result of parsing the body text as JSON . Note that despite the method being named json() , the result is not JSON but is instead the result of taking JSON as input and parsing it to produce a JavaScript object.

The difference is: json() is asynchronous and returns a Promise object that resolves to a JavaScript object. JSON. parse() is synchronous can parse a string to (a) JavaScript object(s).

What is the difference between a text file and a JSON file? A text file contains plain text data, while a JSON file contains structured text data in a format designed for data exchange. JSON files are often used for transmitting data between applications or for storing data in a more organized and structured way.

JSON is standardized and easy to validate. For example, the quotes for string-literals must be ". You can't use apostrophes, spaces, or commas to mark the beginning and end of values like in CSV. This means code to parse or stringify JSON works much more consistently than code involving CSV.

parse() method that can be used to check if a string is a valid JSON. Reading through the documentation, you'll find that JSON. parse() throws a SyntaxError if the string is not a valid JSON. We can use this to our advantage by wrapping the JSON.

Opening JSON files is far more straightforward than you might think; it is a very simple data structure that is entirely text-based — which is why it is limited to strings and numbers.

JSON is a human-readable format for storing and transmitting data. As the name implies, it was originally developed for JavaScript, but can be used in any language and is very popular in web applications. The basic structure is built from one or more keys and values: { "key": value }

JSON stands for JavaScript Object Notation. JSON is a lightweight format for storing and transporting data. JSON is often used when data is sent from a server to a web page.

Why do we do response JSON()? ›

The method makes it easy to create Response objects for returning JSON encoded data. Service workers, for example, intercept fetch requests made by a browser, and might use json() to construct a Response from cached JSON data to return to the main thread.

A JSON object contains zero, one, or more key-value pairs, also called properties. The object is surrounded by curly braces {} . Every key-value pair is separated by a comma. The order of the key-value pair is irrelevant.

Example - Parsing JSON

Use the JavaScript function JSON.parse() to convert text into a JavaScript object: const obj = JSON.parse('{"name":"John", "age":30, "city":"New York"}');

destr is faster generally for arbitrary inputs but also sometimes little bit slower than JSON. parse when parsing a valid JSON string mainly because of transform to avoid prototype pollution which can lead to serious security issues if not being sanitized.

As the name implies, JSON is very similar to JavaScript objects in the way it's written and stored. However, JSON has only properties and no methods. In this introductory article, we will learn what JSON is, the syntax, JSON examples, and why we need JSON.

A JSON file is simply a text file that uses JSON formatting. These files are used to store structured data and are identified by their “. json” extension.

JSON (JavaScript Object Notation) is a text-based data exchange format. It is a collection of key-value pairs where the key must be a string type, and the value can be of any of the following types: Number. String.

If you have a small text file to convert (under 50mb) you can use AnyConv, a website that can convert many different filetypes. Simply upload your TXT file and select to convert it to JSON. If you're trying to convert a text file to JSON that's over 50mb, you'll need to use Microsoft Visual Studio.
