Do you need help with Excel, Google Sheets, or ChatGPT?

About Me

My name is David Jagielski and I have over 15 years experience working with Excel and Google Sheets, creating templates and macros for personal and business use. I’ve worked for over 10 years in accounting and finance, with large, medium and small business, including private, public, and government-run organizations. And for the past seven years, I’ve also been writing about stocks and investing on multiple websites.
