    I'm an engineer who's been working with spreadsheets for over 40 years, creating a wide variety of Excel files, both for engineering work, and also for other projects (such as tax records, business data processing, payroll records, quotations / estimates, stock analysis, church recordkeeping, etc.). I've completed over 1000 different Excel projects for over 300 different clients, in the USA and around the world. My strengths are spreadsheet structure, complex formulas, and VBA macros. Whether you need a complex macro-enabled spreadsheet to automate data processing, or a simple one, I can deliver. NOTE that I work in Excel (for Windows). I do NOT work with Google Sheets or Excel for Mac, since I have found both of those platforms to have some significant incompatibilities with Excel for Windows. Also NOTE that my high number of open contracts is due to many of my clients leaving our Upwork contract open perpetually, so they can come back to me for additional projects. Also note that I have recently closed a number of these long-term (2+ years) open contracts, resulting in a number of "No feedback given" entries in my Job History. These were all satisfied, long-term clients (whom I am now working for directly); there is no feedback because the contracts were closed by me, rather than by the client.
