Welcome to my collection of Excel Portfolio Projects that showcase the depth of my exploration into advanced Excel functionalities and VBA (Visual Basic for Applications) automation. Throughout this journey, I’ve taken on a range of projects that have allowed me to master the key features of Excel, including advanced formulas, pivot tables, Power Query, Power Pivot, and VBA scripting. Each project demonstrates my growing proficiency in transforming raw data into actionable insights, improving workflow efficiency, and automating repetitive tasks.
Mastering keyboard shortcuts was an essential part of my learning process. These shortcuts enabled me to significantly increase my speed and efficiency while working in Excel. The official Microsoft Excel Keyboard Shortcuts guide (here) was invaluable in this regard, helping me navigate tasks more effectively and minimize time spent on manual actions.
The path I followed for mastering Excel was structured to progressively build upon foundational knowledge. Here’s an outline of my approach:
- Fundamentals of Formulas: Started with mastering essential formulas like
SUM,AVERAGE,IF,VLOOKUP, andINDEX-MATCH. - Advanced Formulas: Expanded to complex formulas for financial analysis, dynamic arrays (
FILTER,SEQUENCE), and array functions. - Pivot Tables & Data Analysis: Focused on pivot tables to quickly summarize and analyze large datasets.
- Power Query & Power Pivot: Explored ETL (Extract, Transform, Load) processes to automate data cleaning and integration from multiple sources.
- VBA & Macros: Finally, I dove into VBA, automating workflows with custom scripts and building macros to save time on repetitive tasks.
This journey allowed me to push Excel’s boundaries and leverage its full potential for business intelligence, reporting, and decision-making.
Here’s a list of Excel projects that reflect my progression, highlighting various functionalities I’ve mastered along the way:
- Overview: Built a financial performance dashboard that consolidates profit, revenue, expenses, and KPIs. The dashboard dynamically updates as the data changes.
- Key Features: Data tables, dynamic charts,
SUMIF/SUMPRODUCTformulas, interactive slicers for visualizations. - Outcome: Reduced the time needed for monthly reporting from days to hours.

- Outcome: Helped the marketing team target high-value customers with personalized campaigns.
- Overview: Created a dynamic tool for budgeting and financial forecasting for a business, including variance analysis and trend projections.
- Key Features:
FORECAST,TREND, and financial modeling with Power Pivot. - Outcome: Improved financial planning accuracy and helped achieve a 10% reduction in operational costs.
- Overview: Developed an Excel VBA tool that generates custom reports based on user input, saving hours of manual work each week.
- Key Features: VBA user forms, loops, conditional logic for dynamic report generation.
- Outcome: Streamlined report generation for management, saving significant time.
- Overview: Cleaned and transformed raw sales data from multiple sources into a unified format for analysis.
- Key Features: Power Query for ETL, merging data from different sources, handling null values, and performing data validation.
- Outcome: Reduced errors in reporting by 25% and improved data consistency.
- Overview: Built a tool for evaluating employee performance based on multiple KPIs like productivity, punctuality, and project completion rates.
- Key Features: Nested
IFstatements, conditional formatting to highlight top and underperforming employees, dashboard integration. - Outcome: Allowed HR to identify areas for improvement and reward high performers.
- Overview: Developed a dashboard that tracks project progress, deadlines, and resource allocation.
- Key Features: Gantt charts, conditional formatting for overdue tasks, and custom VBA macros for task updates.
- Outcome: Provided real-time project status updates, enhancing project management efficiency.
- Overview: Analyzed marketing campaign performance by tracking metrics such as conversion rates, engagement, and ROI.
- Key Features: Use of
COUNTIF,SUMIF, and dynamic arrays to aggregate campaign data, visualizing results using charts. - Outcome: Allowed for better decision-making on campaign effectiveness, optimizing marketing spend.
Here are a few additional project ideas that can push your Excel and VBA skills even further:

DATE,WORKDAY), conditional formatting.
- Objective: Design a VBA tool that automatically generates invoices from a database of customer details and transactions.
- Skills Needed: VBA (for dynamic invoice generation), Excel formulas, and data validation.
- Objective: Create a loan amortization table that shows principal and interest payments over time.
- Skills Needed: Excel formulas (
PMT,IPMT,PPMT), charting, and conditional formatting.
- Objective: Build a leave tracking system that calculates and tracks employee leave balances and approvals.
- Skills Needed: Excel formulas (
IF,DATEDIF), conditional formatting, and Power Query for integration with external data sources.
- Objective: Design a task tracker with built-in priority and deadline management, automating task updates.
- Skills Needed: Excel formulas, conditional formatting, VBA (for task updates).
This repository demonstrates the breadth of projects I’ve undertaken to harness advanced Excel features and VBA scripting.
