Template Generator - AI-Powered Dynamic Form Builder

Web application that transforms Excel files into intelligent, dynamic forms using cutting-edge AI technology.

🎯 Project Overview

Template Generator is a Gen AI - full-stack application that bridges the gap between raw data and interactive user interfaces. By leveraging OpenAI's language models, it automatically analyzes Excel files and generates comprehensive JSON schemas, which are then transformed into dynamic, responsive forms.

This isn't just another form builder—it's an intelligent system that understands your data structure and creates production-ready forms with minimal human intervention.

⚡ Core Features

AI-Powered Schema Generation

• Intelligent Analysis: Automatically detects data types, patterns, and relationships from Excel files
• Smart Field Recognition: Identifies required fields, validation rules, and data constraints
• Context-Aware Processing: Uses OpenAI to understand semantic meaning of column headers and data

Dynamic Form Engine

• Real-Time Rendering: Instantly generates forms using react-jsonschema-form
• Interactive Preview: Test forms immediately after generation
• Responsive Design: Forms adapt seamlessly to all device sizes

Advanced Schema Editor

• Visual Schema Builder: Intuitive interface for modifying generated schemas
• Type System: Support for strings, numbers, booleans, arrays, and complex objects
• Validation Rules: Custom validation patterns and constraints
• Field Properties: Configure labels, descriptions, and UI hints

Enterprise-Grade Storage

• PostgreSQL Backend: Robust data persistence for templates and schemas
• Version Control: Track schema changes and form iterations
• Template Library: Reusable templates for common use cases

🏗️ Technical Architecture

Educational Institutions

Convert academic forms, surveys, and data collection sheets into interactive digital experiences.

🔧 Quick Start

# Clone the repository
git clone https://github.com/STarLo-rd/template-generator.git
cd template-generator

# Set up database
createdb template_generator
psql -d template_generator -f database/schema.sql

# Configure environment
cp .env.example .env
# Add your OpenAI API key and database credentials

# Install and start backend
cd server
npm install
npm run dev

# Install and start frontend
cd ../client
npm install
npm start

🎨 Workflow

1. Upload Excel File → AI analyzes structure and content
2. Review Generated Schema → Intelligent field detection and type inference
3. Customize Schema → Fine-tune fields, validation, and properties
4. Preview Form → Test the generated form in real-time
5. Save Template → Store for reuse and future iterations
