Replay: Convert Excel Spreadsheet Mockups to React Apps

TL;DR: Replay converts video recordings of Excel spreadsheet mockups into functional React applications, saving development time and ensuring accurate implementation of user intentions.

Excel is a powerful tool. It's often the starting point for designing user interfaces and data structures. But translating an Excel spreadsheet mockup into a fully functional React application is a notoriously tedious and error-prone process. Manually coding each component, replicating the spreadsheet's logic, and ensuring visual fidelity consumes valuable development time. Screenshot-to-code tools fall short because they don't understand the intent behind the design. They only see pixels.

This is where Replay shines. Replay is a revolutionary video-to-code engine that uses Gemini to reconstruct working UI from screen recordings. It understands behavior. Instead of just seeing the static layout of your Excel mockup, Replay analyzes the actions you take: the formulas you enter, the data you manipulate, the interactions you simulate. This "Behavior-Driven Reconstruction" approach allows Replay to generate React code that accurately reflects your intended functionality.

Why Video-to-Code is a Game Changer#

Traditional methods of translating mockups into code often involve:

1. •Static screenshots: These lack the dynamic behavior and context of the intended application.
2. •Manual coding: Time-consuming and prone to errors, especially when dealing with complex logic.
3. •Communication gaps: Misinterpretations between designers and developers can lead to costly rework.

Replay addresses these challenges by:

• •Analyzing video recordings of your Excel mockup to understand the underlying logic and user interactions.
• •Generating clean, efficient, and functional React code that accurately reflects your design.
• •Bridging the communication gap between design and development, ensuring everyone is on the same page.

Converting Your Excel Mockup to React with Replay: A Step-by-Step Guide#

Here's how to convert your Excel spreadsheet mockup into a functional React application using Replay:

Step 1: Record a Video of Your Excel Mockup#

Record a clear video demonstrating the functionality of your Excel spreadsheet. Make sure to:

• •Show all relevant columns, rows, and formulas.
• •Demonstrate user interactions, such as data entry, filtering, and calculations.
• •Clearly articulate the intended behavior of the application.

💡 Pro Tip: Keep the video concise and focused. Avoid unnecessary distractions or irrelevant actions. A well-defined video leads to more accurate code generation.

Step 2: Upload Your Video to Replay#

Navigate to the Replay platform (https://replay.build) and upload your video recording.

Step 3: Configure Replay Settings#

Configure the following settings:

• •Target Framework: Select "React" as the target framework.
• •Component Structure: Choose how you want your application to be structured (e.g., single-page application, multi-page application). Replay supports multi-page generation!
• •Style Injection: Select your preferred styling method (e.g., CSS modules, Styled Components, Tailwind CSS).
• •Supabase Integration: If your application requires a database, you can seamlessly integrate with Supabase.

Step 4: Generate the React Code#

Click the "Generate Code" button. Replay will analyze your video and generate the corresponding React code. This process may take a few minutes, depending on the complexity of your mockup.

Step 5: Review and Refine the Generated Code#

Once the code generation is complete, review the generated code in the Replay editor. You can:

• •Inspect the component structure and code logic.
• •Make any necessary adjustments or refinements.
• •Download the generated code as a React project.

⚠️ Warning: While Replay strives for accuracy, it's crucial to review the generated code and ensure it meets your specific requirements. AI-generated code, even with Replay, requires human oversight.

Step 6: Integrate the Code into Your Project#

Integrate the generated React code into your existing project. You may need to:

• •Install any required dependencies.
• •Configure routing and navigation.
• •Connect the application to your data sources.

Example: Recreating a Simple Budget Tracker#

Let's say you have an Excel spreadsheet that tracks your monthly budget. It has columns for:

• •Date
• •Description
• •Category
• •Income
• •Expense

You also have formulas to calculate the total income, total expenses, and remaining balance.

Using Replay, you can easily convert this spreadsheet into a React application. The generated code might look something like this:

typescript
// src/components/BudgetTracker.tsx
import React, { useState, useEffect } from 'react';
import './BudgetTracker.css'; // Assuming CSS Modules

interface Transaction {
  date: string;
  description: string;
  category: string;
  income: number;
  expense: number;
}

const BudgetTracker = () => {
  const [transactions, setTransactions] = useState<Transaction[]>([]);
  const [totalIncome, setTotalIncome] = useState<number>(0);
  const [totalExpenses, setTotalExpenses] = useState<number>(0);
  const [remainingBalance, setRemainingBalance] = useState<number>(0);

  useEffect(() => {
    // Placeholder for fetching data from Supabase or local storage
    // Replace with your actual data fetching logic
    const initialTransactions: Transaction[] = [
      { date: '2024-01-01', description: 'Salary', category: 'Income', income: 5000, expense: 0 },
      { date: '2024-01-05', description: 'Rent', category: 'Housing', income: 0, expense: 1500 },
      { date: '2024-01-10', description: 'Groceries', category: 'Food', income: 0, expense: 300 },
    ];
    setTransactions(initialTransactions);
  }, []);

  useEffect(() => {
    const income = transactions.reduce((acc, transaction) => acc + transaction.income, 0);
    const expenses = transactions.reduce((acc, transaction) => acc + transaction.expense, 0);
    setTotalIncome(income);
    setTotalExpenses(expenses);
    setRemainingBalance(income - expenses);
  }, [transactions]);

  return (
    <div className="budget-tracker">
      <h1>Budget Tracker</h1>
      <table>
        <thead>
          <tr>
            <th>Date</th>
            <th>Description</th>
            <th>Category</th>
            <th>Income</th>
            <th>Expense</th>
          </tr>
        </thead>
        <tbody>
          {transactions.map((transaction, index) => (
            <tr key={index}>
              <td>{transaction.date}</td>
              <td>{transaction.description}</td>
              <td>{transaction.category}</td>
              <td>{transaction.income}</td>
              <td>{transaction.expense}</td>
            </tr>
          ))}
        </tbody>
      </table>
      <div className="summary">
        <p>Total Income: ${totalIncome}</p>
        <p>Total Expenses: ${totalExpenses}</p>
        <p>Remaining Balance: ${remainingBalance}</p>
      </div>
    </div>
  );
};

export default BudgetTracker;

This is a simplified example, but it demonstrates how Replay can generate functional React code from your Excel mockup. You can then customize this code to add more features and functionality.

Replay's ability to understand and translate spreadsheet logic into code is a significant advantage over screenshot-to-code tools. It saves you time and effort while ensuring that your React application accurately reflects your intended design.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features. Paid plans are available for more advanced features and higher usage limits. Check the Replay website for the latest pricing information.

How is Replay different from v0.dev?#

v0.dev primarily focuses on generating UI components from text prompts. Replay, on the other hand, analyzes video recordings to understand user behavior and intent, enabling it to generate more accurate and functional code, especially when dealing with complex logic and interactions. Replay excels at understanding the how (user actions) in addition to the what (visual appearance).

What types of Excel spreadsheets can Replay convert?#

Replay can convert a wide range of Excel spreadsheets, from simple data tables to complex financial models. The key is to provide a clear and concise video recording that demonstrates the functionality of your spreadsheet.

What if the generated code isn't perfect?#

Replay is designed to generate high-quality code, but it's not a replacement for human review. You can always refine the generated code in the Replay editor or in your IDE. The goal is to significantly reduce the amount of manual coding required.
