How to Extract and Display Only the Year from JSON Data- A Comprehensive Guide

How to Pass Only Year in JSON Data

In today’s digital world, JSON (JavaScript Object Notation) has become a popular format for data interchange. JSON is lightweight, easy to read, and easy to write. However, when dealing with date and time data, it’s often necessary to pass only the year part. This article will guide you through the process of passing only the year in JSON data, ensuring that your data remains concise and accurate.

Understanding JSON Data Format

Before diving into the process of passing only the year in JSON data, it’s essential to understand the JSON data format. JSON is a text-based data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, but it is language-independent, with parsers available for virtually every programming language.

JSON data is represented as key-value pairs, enclosed in curly braces. For example:

“`json
{
“name”: “John Doe”,
“age”: 30,
“birthdate”: “1990-01-01”
}
“`

In this example, the `birthdate` key contains a date string. To pass only the year part of this date, we need to modify the JSON data accordingly.

Passing Only the Year in JSON Data

To pass only the year in JSON data, you can follow these steps:

1. Extract the year from the date string.
2. Replace the date string with the extracted year.
3. Convert the JSON data to a string format if necessary.

Here’s an example of how to do this in JavaScript:

“`javascript
// Original JSON data
let jsonData = {
“name”: “John Doe”,
“age”: 30,
“birthdate”: “1990-01-01”
};

// Extract the year from the birthdate
let year = jsonData.birthdate.split(‘-‘)[0];

// Replace the birthdate with the year
jsonData.birthdate = year;

// Convert the JSON data to a string format
let jsonString = JSON.stringify(jsonData);

console.log(jsonString);
“`

The output will be:

“`json
{
“name”: “John Doe”,
“age”: 30,
“birthdate”: “1990”
}
“`

In this example, we extracted the year “1990” from the `birthdate` key and replaced the entire date string with just the year.

Conclusion

Passing only the year in JSON data can be a straightforward process when you understand the data format and the necessary steps. By following the guidelines outlined in this article, you can ensure that your JSON data remains concise and accurate, making it easier to work with and share.
