Paste this sample data:

{
  "name": "Harsh",
  "age": 21,
  "city": "Delhi"
}

Click Insert. Your first document is now saved in MongoDB.

Step 7: Test MongoDB Using Commands

Open Command Prompt and run:

mongosh

Now run these commands one by one:

use testdb

db.users.insertOne({
  name: "Harsh",
  age: 21
})

db.users.find()

If your data appears on screen, MongoDB is working perfectly.

Common MongoDB Errors and Fixes

1. mongosh is not recognized

This error means MongoDB Shell path is not added to Environment Variables.

Add this path:

C:\Program Files\MongoDB\Server\8.0\bin

After adding the path, restart Command Prompt and try again.

2. Connection Refused Error

This error usually means MongoDB service is not running.

Run Command Prompt as Administrator and type:

net start MongoDB

Install MongoDB with Node.js

If you are learning backend development or MERN stack, install Mongoose in your Node.js project.

npm install mongoose

Simple MongoDB connection example:

const mongoose = require("mongoose");

mongoose.connect("mongodb://127.0.0.1:27017/testdb")
.then(() => console.log("MongoDB Connected"))
.catch(err => console.log(err));

Final Thoughts

Installing MongoDB on Windows is very easy when you follow the correct steps. After installation, you can start learning CRUD operations, Mongoose, Express.js integration, authentication systems, APIs, and MERN stack development.
