AI + Rule-Based Excel Automation Expert

If you're stuck doing the same spreadsheet steps every day or week, that work can almost always be automated. I've spent over 20 years writing VBA that turns slow, error-prone Excel processes into reliable, one-click tools. I'm a Top-Rated Plus freelancer with a 100% Job Success Score, $100K+ earned, over 150 completed jobs, and five-star reviews. What sets my work apart is that I start by understanding your process: ▪️ What are you doing today? ▪️ Where does your data come from, and where is it stored? ▪️ What decisions are people making? ▪️ What work is repetitive? ▪️ What should be automated? ▪️ What requires human review or approval? ▪️ What happens when something goes wrong? Once those expectations are defined, I determine the best way to automate the process and build the solution around those requirements. AI is a powerful tool, but it doesn't replace the experience required to design reliable automation. Someone still needs to define what should happen, what triggers it, how exceptions are handled, what gets logged, and what happens when something goes wrong. That's the work I've been doing for more than 20 years. I use AI tools such as Gemini and ChatGPT where they add value, including exploring approaches, reviewing code for potential weaknesses, and enhancing functionality. AI supports my experience rather than replacing it. The design, logic, testing, and final result remain my responsibility. What it's like to hire me: ▪️ Thoroughly tested. I test individual components, how they work together, and the complete process end to end. ▪️ No budget surprises. On fixed-price jobs, the quote is what you pay. On hourly jobs, I provide an estimate before starting. ▪️ Clear communication. I raise limitations and potential issues early, provide progress updates, and help you through setup and first use. ▪️ Your data stays private. I treat your files and business information as confidential and never enter your confidential data into AI tools. I'm also happy to sign an NDA. What I build in Excel: ▪️ Routine and multi-step process automation ▪️ Data cleaning, consolidation, and import/export ▪️ Automated reports and dashboards ▪️ PivotTables, Power Query, formulas, and custom functions ▪️ Custom forms, buttons, and user-friendly interfaces ▪️ Add-ins, ribbon controls, and hotkeys ▪️ Validation, exception handling, and automated logging Have a project in mind? Send me a message or schedule a call. Let's define what your process needs to do and determine the best way to automate it. Thank you, Mattie Owens
