Create dynamic table from JSON in React js

In this tutorial, you will learn to create a dynamic table from a JSON array of objects in react js with some simple steps that are very easy to understand and implement in web applications.

If you use React dynamic table functionality for creating web applications It will automatically or dynamically add rows & columns to the table if you add more JSON object data. So, you will need not add static rows & columns by modifying the react js code.

For example, you can see a table with a total of 5 rows & columns like id, fullName, gender, age, & city. It is created using JSON data.

Now, If you need to add one more column named email then just add email data in each JSON object. after that It will be automatically added to the table.

Also, If you need to add one more row of data then just add one more JSON object data. after that, it will be also automatically added to the table.

  |       |__DynamicTable.js

I have used bootstrap 4 to create a responsive weather app. So, You should run the following command

1. Create JSON Array Data

Table Name – TableData.js

const TableData=[
    {id:1, fullName:"Noor Khan", age:25, city:"Patna"},
    {id:2, fullName:"Rapsan Jani", age:26, city:"Noida"},
    {id:3, fullName:"Monika Singh", age:18, city:"New Delhi"},
    {id:4, fullName:"Sunil Kumar", age:22, city: "Jaipur"},
    {id:5, fullName:"Kajol Kumari", age: 21, city: "Chennai"}
export default TableData;

2. Create Dynamic Table Component

Table Name – DynamicTable.js

import { useEffect } from "react";
import TableData from "./TableData";
function DynamicTable(){

// get table column
 const column = Object.keys(TableData[0]);

 // get table heading data
 const ThData =()=>{
         return <th key={data}>{data}</th>

// get table row data
const tdData =() =>{
                       return <td>{data[v]}</td>

  return (
      <table className="table">
export default DynamicTable;

3. Render Dynamic Table Component

To render the Dynamic Table component, You should import it into the App component and return   <DynamicTable />.

File Name – App.js

import "../node_modules/bootstrap/dist/css/bootstrap.min.css";
import DynamicTable from "./dynamic-table/DynamicTable";
function App() {
  return (
    <DynamicTable />
export default App;


4. Test Dynamic Table Yourself

Now, you can test the Dynamic Table yourself  by running the React App with the following command
