How to Iterate JSON to Create a Table Row-wise Using jQuery

In today’s digital landscape, data manipulation is a frequent task that developers encounter. One common requirement is converting JSON data into a structured HTML table. If you've found yourself wondering how to accomplish this, you're not alone! In this post, we will explore how to take a JSON structure representing students' scores and display it neatly in a table format using jQuery.

Understanding the Problem

Imagine you have a JSON object containing student scores in different subjects, structured as follows:

You want to present this data in a table that looks like this:

However, the structure of the JSON makes it a bit challenging to extract and organize the data. Let's break it down step by step.

Solution Breakdown

Step 1: Simplify the Data Structure

First, we need a better-structured JSON object that makes accessing the data easier. Instead of having nested objects, we can reorganize the JSON as follows:

Step 2: Extracting Student Data

Now, we can easily access the student data from this new structure. The goal is to convert it into a 2D format where subjects are rows and students are columns. Here’s how to do it with jQuery:

Step 3: Creating the Table

Next, we need to create the HTML table dynamically. This involves looping through the marks object and constructing header and body rows.

Result

As a result, when you run the above JavaScript code in conjunction with the HTML document containing a <div id="app"></div>, it will generate a neatly organized table from the JSON data.

Conclusion

By following this simple yet effective approach, you can easily iterate through JSON data to output a structured HTML table. This method also allows for scalability, as it can adapt to varying numbers of students and subjects without additional modifications.

Whether for personal projects or professional applications, mastering this technique can significantly enhance your front-end development skills. Happy coding!
