The goal was to automate data analysis processes, summarize stock performance, and visualize trends across multiple worksheets efficiently.\n\n## Project Overview\n\nThe VBA script automates the following tasks:\n- Loops through multiple worksheets containing stock data.\n- Calculates yearly stock performance metrics:\n  - Total Stock Volume\n  - Yearly Change in Stock Price\n  - Percent Change in Stock Price\n- Applies conditional formatting for positive/negative changes.\n- Outputs a summary table of key metrics for each stock ticker.\n\n## Tools \u0026 Technologies Used\n- VBA (Visual Basic for Applications)\n- Excel (.xlsm)\n- Excel Conditional Formatting\n- Excel Formulas \u0026 Functions\n\n## File Structure\n\n```text\nResources/\n├── Multiple_year_stock_data.xlsm - Main Excel workbook with VBA code\n├── alphabetical_testing.xlsx - Data file for testing\n\nScreenshots/\n├── Multiple_Year_Stock_Data_Q1.png\n├── Multiple_Year_Stock_Data_Q2.png\n├── Multiple_Year_Stock_Data_Q3.png\n├── Multiple_Year_Stock_Data_Q4.png\n\nVBA Script/\n├── Multiple_Year_Stock_Data_Script.bas - VBA code script\n```\n\n## Skills Demonstrated\n- Automating repetitive Excel tasks with VBA\n- Writing loops and conditional logic in VBA\n- Summarizing large datasets programmatically\n- Applying conditional formatting dynamically\n- Structuring clean and modular code\n\n## Sample Output\n\nVisualizations of the summary output per quarter:\n\n![Q1 Summary](Screenshots/Multiple_Year_Stock_Data_Q1.png)\n![Q2 Summary](Screenshots/Multiple_Year_Stock_Data_Q2.png)\n![Q3 Summary](Screenshots/Multiple_Year_Stock_Data_Q3.png)\n![Q4 Summary](Screenshots/Multiple_Year_Stock_Data_Q4.png)\n\n## Key Takeaways\n- Automating stock analysis saves time and reduces errors compared to manual calculations.\n- VBA is powerful for data manipulation and reporting within Excel.\n- Visualizing stock performance across multiple years provides clearer insights for decision making.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffbarffmann%2Fvba-challenge","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffbarffmann%2Fvba-challenge","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffbarffmann%2Fvba-challenge/lists"}
