Creating a spreadsheet-like user interface similar to Google Sheets using JavaScript involves combining several web technologies, including HTML for structure, CSS for styling, and JavaScript for interactive features. To achieve a rich, real-time collaborative spreadsheet, you'll likely need to use a combination of frontend frameworks/libraries and backend services. Here’s a step-by-step guide on how you could approach this with JavaScript:

Frontend

HTML/CSS:
- Create the basic layout using HTML.
- Style it to look like a spreadsheet using CSS. You can use grid or flexbox to structure the cells.
JavaScript Framework:
- React: Use React for building the user interface because of its efficient rendering and state management capabilities.
- Vue.js: Alternatively, Vue.js is user-friendly and simpler to integrate for smaller projects.
Spreadsheet Library:
- Handsontable: This is a JavaScript/HTML5 data grid component with spreadsheet look and feel. It is very customizable and can integrate seamlessly with React or Vue.js.
- x-spreadsheet: A web-based JavaScript spreadsheet that is lightweight and easy to integrate.
State Management:
- Use Redux or Vuex to manage state across the spreadsheet, especially if your spreadsheet is complex and requires features like undo/redo or binding with external data sources.

Backend

Node.js:
- Utilize Node.js to handle backend operations such as authentication, data storage, and real-time communication.
- Frameworks like Express can simplify the creation of RESTful APIs to interact with your frontend.
Real-time Communication:
- Socket.IO: This is perfect for real-time data synchronization across multiple clients, making it ideal for collaborative tools.
- WebRTC: Can be used for peer-to-peer data sharing, though it’s more complex to set up compared to Socket.IO.
Database:
- MongoDB: A NoSQL database like MongoDB can store document-based data, which is useful for storing complex spreadsheet data.
- PostgreSQL: If your data needs complex relations or you prefer SQL, PostgreSQL is a robust choice.

Full Example Setup Using React and Socket.IO

Here’s how you could architect a simple collaborative spreadsheet application:

Frontend (React)

// React component to render the spreadsheet
import React, { useEffect, useState } from 'react';
import Handsontable from 'handsontable';

function SpreadsheetComponent() {
    const [data, setData] = useState([['']]);

    useEffect(() => {
        const container = document.getElementById('spreadsheet');
        const hot = new Handsontable(container, {
            data: data,
            rowHeaders: true,
            colHeaders: true,
            afterChange: (changes) => {
                if (changes) { // changes is null when setData triggers rerender
                    socket.emit('update', changes);
                }
            }
        });

        // Socket.io client listening to data updates
        socket.on('data_updated', newData => {
            setData(newData);
            hot.loadData(newData); // Load new data into Handsontable
        });

        return () => {
            hot.destroy();
        };
    }, []);

    return <div id="spreadsheet"></div>;
}

Backend (Node.js with Socket.IO)

// Server setup with Socket.IO
const express = require('express');
const http = require('http');
const socketIo = require('socket.io');

const app = express();
const server = http.createServer(app);
const io = socketIo(server);

let spreadsheetData = [['']]; // Initial spreadsheet data

io.on('connection', (socket) => {
    socket.emit('data_updated', spreadsheetData);

    socket.on('update', (changes) => {
        // Apply changes to spreadsheetData
        changes.forEach(([row, col, oldValue, newValue]) => {
            if (spreadsheetData[row]) {
                spreadsheetData[row][col] = newValue;
            }
        });
        io.emit('data_updated', spreadsheetData); // Broadcast updated data
    });
});

server.listen(3000, () => console.log('Server listening on port 3000'));

Conclusion

The combination of React, Node.js, Socket.IO, and a spreadsheet library like Handsontable can create a powerful, interactive, and real-time collaborative spreadsheet application similar to Google Sheets. You can expand this basic setup with additional features like cell formatting, formulas, and more sophisticated state management as needed.
