Marcos Roberto de Souza

I’m Marcos Roberto de Souza, an Embedded Software Engineer at a multinational company in the refrigeration sector, and the founder of Smart Builder Tool. With nearly 30 years of programming experience, I’ve combined my technical background with in-depth Excel expertise to develop tools that help individuals and businesses automate tasks, reduce errors, and boost daily productivity.

 

Through Smart Builder Tool, my goal is not only to deliver high-quality Excel-based solutions, but also to share knowledge. I’m committed to creating professional-grade tools—whether in the form of add-ins or macro-enabled spreadsheets—that are both practical and educational. Many of these tools are free and open-source, allowing users to explore the VBA code and better understand how each solution is built.

 

This project reflects my dedication to programming and to helping others work smarter with Excel. Every tool is developed with care, professionalism, and the goal of earning your trust through quality and transparency.

🚀 Our Mission

We believe that automation and learning go hand in hand. That’s why we develop advanced Excel-based solutions—like Smart UI, Smart Gantt, Smart Tools, Smart Cal, and Excel AppMaker—that deliver:

 

  • ✔️ Real functionality: from automated forms to Gantt charts

  • 💡 Built-in learning: fully open-source VBA code for you to explore, understand, and customize

  • 🤝 Practical application: tools created and tested using real-world problems—especially in industry and office environments

🛡️ Safety & Trust

  • My tools do not contain viruses or malicious code—everything is carefully programmed by me with attention to detail and best coding practices.

 

  • Excel is widely used in professional environments, and that’s why quality and transparency are essential.

 

  • By offering open-source solutions, I show complete confidence in the tools I deliver.
