Stringfest Analytics

Modern Excel + AI systems that make your analysts faster, smarter, and more reliable.

Hi, I am George. I am an O'Reilly author, a Microsoft MVP, and a LinkedIn Learning instructor.

I help teams modernize the way they use Excel. When you combine Excel with tools your organization already has like Python, Copilot, Power Query, and Power Automate, you get faster analysis, fewer errors, stronger documentation, and workflows that scale.

My goal is to help your analysts work with clarity and confidence, spend less time fighting spreadsheets, and finish the day with less stress and more control over their work.
