🤖 Implemented Components

✅ 10 Core Agents (All Implemented)

  1. File Ingest Agent - Excel file loading, parsing, and metadata extraction
  2. Structure Scan Agent - Merged cells, charts, images, and formulas detection
  3. Column Profiling Agent - Data type inference and statistical analysis
  4. Merge Handling Agent - Multiple strategies for merged cell processing
  5. Labeling Agent - Intelligent column and cell labeling with ML
  6. Code Generation Agent - Natural language to pandas/openpyxl code conversion
  7. Execution Agent - Sandboxed Python code execution with safety checks
  8. Summarization Agent - Data summarization and key insights generation
  9. Memory & Preference Agent - User context and preference management
  10. Relation Discovery Agent - Multi-table relationship detection and recommendations

✅ Orchestrator System

  • Workflow Management: Coordinates agent execution in proper sequence
  • Error Handling: Comprehensive error tracking and recovery
  • Result Integration: Combines outputs from multiple agents

✅ Three Main Workflows Implemented

  1. Single-Table Workflow: File Ingest → Column Profiling → Code Generation → Execution
  2. Single-Cell Workflow: File Ingest → Profiling → Code Generation (filters) → Execution
  3. Multi-Table Workflow: File Ingest → Multi-table Profiling → Relation Discovery → Code Generation → Execution

✅ AI Integration (SiliconFlow API)

async def main():
    orchestrator = Orchestrator()
    
    # Process natural language query
    result = await orchestrator.process_user_request(
        user_request="Show me the total sales by region",
        file_path="./data/sales_data.xlsx"
    )
    
    print(f"Status: {result['status']}")
