Hello, I am in Cincinnati, OH and have expert experience with MS Access, VBA, and really "all things data". Please allow me a few minutes to describe why I am the perfect and best fit for your project. I really am great at all things "data related" including data profiling, data analysis, data modeling, building the applications to input and display the data, and then also reporting on the data. I have much experience with reading in files automatically, transforming the data into information, then displaying the output to the user. I have complete libraries of reusable VBA code, forms, and reports which I can quickly add to any new application and make it extremely nice, very quickly!  After review, I think you will agree that I am a perfect fit for your project and you can put your trust in me. Lastly, be aware that you will probably get some very low offers, but I assure you they will not have the experience nor reputation that I do. I am confident that you do not want to risk this project on someone who only won the bid because they were the cheapest option but not the best partner for the job.  With this experience, I think we can be a perfect fit for each other.  Thanks for considering,  Holly Murphy YittBox.com

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.
