I'm an Excel VBA Developer specializing in AI-powered automation systems that eliminate manual, repetitive spreadsheet work and turn it into a single button click. My clients get back 10 to 30 hours every week — not by working harder, but by finally having a system that works for them. 💰 WHAT THIS MEANS FOR YOUR BUSINESS: • Manual report that takes 4 hours → runs in 4 minutes • Invoice that needs copy-pasting across 3 files → auto-generated and emailed in one click • Payroll calculated by hand every month → automated, error-free, PDF payslips included • Data stuck in PDFs or CSVs → auto-imported, cleaned, and sorted into your Excel system 🔧 WHAT I BUILD: 𝗩𝗕𝗔 & 𝗠𝗮𝗰𝗿𝗼 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 Automate data entry, processing, reporting, and file management — no more manual steps, no more errors. 𝗔𝗜-𝗣𝗼𝘄𝗲𝗿𝗲𝗱 𝗘𝘅𝗰𝗲𝗹 𝗧𝗼𝗼𝗹𝘀 I integrate Python and AI APIs directly with Excel VBA — giving you smart dashboards, auto-cleaning data pipelines, and intelligent reporting that goes beyond what pure VBA can do. 𝗖𝘂𝘀𝘁𝗼𝗺 𝗨𝘀𝗲𝗿𝗙𝗼𝗿𝗺𝘀 & 𝗗𝗮𝘁𝗮 𝗘𝗻𝘁𝗿𝘆 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Professional, user-friendly forms with validation, dropdown menus, and automatic database storage — built for non-technical teams to use without training. 𝗣𝗗𝗙 & 𝗢𝘂𝘁𝗹𝗼𝗼𝗸 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 Auto-generate PDFs (invoices, payslips, reports), extract data from PDF files, and send personalized emails through Outlook — all triggered from Excel. 𝗗𝘆𝗻𝗮𝗺𝗶𝗰 𝗗𝗮𝘀𝗵𝗯𝗼𝗮𝗿𝗱𝘀 & 𝗥𝗲𝗽𝗼𝗿𝘁𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Interactive KPI dashboards, real-time reports, and drill-down charts that update automatically — no manual refresh needed. 𝗙𝗶𝗻𝗮𝗻𝗰𝗶𝗮𝗹 & 𝗛𝗥 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 Payroll calculators, invoice generators, budget trackers, leave management, and financial forecasting tools — built end-to-end in Excel VBA. 𝗗𝗮𝘁𝗮 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻 & 𝗜𝗺𝗽𝗼𝗿𝘁𝘀 Connect Excel to APIs, databases, and external files (CSV, XML, JSON, PDF). Pull live data, auto-import, auto-clean — no manual copy-paste ever again. 𝗠𝗮𝗰𝗿𝗼 𝗗𝗲𝗯𝘂𝗴𝗴𝗶𝗻𝗴 & 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 Broken macros, slow files, legacy workbooks that nobody understands anymore — I fix, clean, and optimize them fast. 📊 REAL RESULTS FROM REAL PROJECTS: ✔ Built an invoice automation system for an accounting firm — eliminated 12 hours/week of manual entry, zero errors since deployment ✔ Developed a full HR payroll & PDF payslip system for a 150-employee company — what took 3 days now runs in 20 minutes ✔ Created an inventory tracking dashboard with auto-reorder alerts for a retail client — stock shortages dropped by 80% ✔ Overhauled a broken legacy VBA system for a logistics company — processing time cut by 60%, file crashes eliminated ✔ Built an AI-integrated data cleaning pipeline that processed 50,000+ records automatically — what their team did in 2 days now runs overnight 🏭 INDUSTRIES I SERVE: Finance & Accounting | HR & Payroll | Retail & E-commerce | Logistics & Supply Chain | Real Estate | Healthcare | Construction | Education ⚡ WHY CLIENTS CHOOSE ME — AND KEEP COMING BACK: Most VBA developers write code that works once. I build systems that work forever. Every tool I deliver comes with: ✅ Clean, commented code — so any developer can maintain it later ✅ Full documentation + video walkthrough — your team gets it from day one ✅ Post-delivery support — I don't disappear after payment ✅ Scalable architecture — built to grow with your business, not break under pressure And unlike most Excel freelancers who only know VBA, I combine deep VBA expertise with Python automation and AI integration — meaning your solution isn't limited to what Excel can do alone. 💬 WHAT CLIENTS SAY ABOUT WORKING WITH ME: "I've worked with 5 other freelancers on this project — they all gave up. This developer delivered exactly what I needed and explained every step." "Fast, professional, and the system works perfectly. Already saving us hours every week."

Hi. My name is Rob Mendell. I'm a Top-Rated Upwork Contractor. I've been a full-time Independent since 2007. • I develop bespoke automation solutions in Word and Excel (and some PowerPoint) using VBA. • I am a Microsoft Certified Master Instructor for Microsoft Office. • I provide issue support like a Help Desk (headers and footers, formulas, whatever). • I assist with, or fully complete, special projects. —|— What do I offer? VBA Development — It's been said that if you want to really learn something, program a computer to do it. I'm a VBA Programmer. VBA -- Visual Basic for Applications -- is a language Microsoft built into some Office applications that allows Developers to create tailor-made dialog boxes and write software code that taps into the objects and power inherent within each application. I know how to create customizations and one-of-a-kind automation inside Microsoft Office using VBA (Word, Excel, and PowerPoint), with a friendly yet professional user interface, when the job requires this. Most people I work with on Upwork were initially unaware of this functional possibility, especially inside Word. Training — It's also been said that if you want to really learn something, teach it. I've been teaching Microsoft Office since 1992: in classroom settings, virtually, and through on-demand deskside services such as Tier 2 and Tier 3 Support. I know what the software can do natively -- without customization -- and how to patiently and clearly present it as a learning opportunity in layman's terms: Word styles, Excel formulas, PowerPoint slide masters, templates, conditional mail merge, and so on. Very few contractors have skills as both a Developer and a Trainer. I do. That's what I offer. I typically approach training from technical awareness, and I approach automation from the user's experience. If Office already has a feature built in, we shouldn't spend time and money to develop specialized code to do the job. I can look at a project and quickly determine which service is best in your specific situation, and then provide it to you. Your deliverable may be a combination of customized development, creation of a special project that uses it, and training on working with tools already available in the software suite. I offer a strong, coherent, and unique set of professional services to companies who want to more fully leverage their investment in Microsoft Office, with workbooks, documents, presentations, and automation templates. —|— Here are examples: VBA Development — Using VBA (Visual Basic for Applications), I design customized and intelligent dialog boxes that ask the pertinent questions, acquire the required answers, and then automate the desired results. I deliver these solutions most often as macro-enabled templates (.dotm for Word, .xltm for Excel, and .potm for PowerPoint). Examples of completed projects include correspondence layouts, code-generated PowerPoint decks, report generators based on sales or survey data, time sheets that perform calculations, budget workbooks that allocate every penny based on performance and longevity ratios, documents that behave, proposal and SOW templates, and so much more. Training — I love teaching Word and Excel, from beginning topics through advanced. I've also taught Outlook, PowerPoint, OneNote, and other programs. I've been teaching Microsoft Office for 30 years. Support — Everyone gets stuck now and then, and you may need assistance. I am available to help you get a complex Word document back on track with styles and multi-section page numbering, or write that elusive set of formulas in Excel. I can work like an experienced outsourced Help Desk or write great documentation to help your employees understand and utilize functionality. Special Projects — Not everyone has the inclination or time to become a power user. I am available to help you by creating an intricate Excel workbook, designing and producing a process illustration or trail graphic in PowerPoint, or applying styles throughout your document and giving it a style-generated Table of Contents. —|— Who hires me? I've worked for 90 law firms, plus companies in a number of other industries including healthcare, manufacturing, finance (banking, capital management, credit, etc.), government, document storage, hotels and hospitality, energy and emissions, data, automotive, museum displays, order fulfillment, insurance, staffing, communication, education, software and technology, construction and renovation, personal growth and coaching, retail sales, executive search, inspections, and many others. If you want more from Microsoft Office in the form of development, training, support, or special projects, or if your document is wonky, or if you're stuck and don't know what you need, let's talk. =Rob Mendell

"The difference between ordinary and extraordinary is that little extra." ~ Jimmy Johnson My past clients include PhDs, CEOs, Company Founders, and otherwise those at the top of their respective expertise. With industries ranging from veterinarian training, oil drilling, special education, law, wealth management, and language translation to name a few. In scope, these projects have spanned from small personal budgets to revenue calculations for the world-class Waldorf Astoria hotel. Regardless of circumstance, my primary goal is to bring your ideas to life in Excel while demonstrating the promptness and respect you deserve. To provide both the technical knowledge to complete a project and the ability to explain it in simple terms is what I have done best for over 7 years. During a project, I act as the sole point of contact. My corporate background includes J.P. Morgan Chase & Co., BlackRock Inc., and Wells Fargo & Company. My education includes a Bachelor’s in Finance from the University of Delaware and an Excel certification from Microsoft. Common projects include dashboards, cost estimators, and time trackers. I place a high emphasis on communication and will take the time to be sure that you are content with all aspects of a project before closing. When necessary, I have also created video tutorials on using your new workbook. Feel free to ask any questions regarding my experience and how I can help. Below are some reviews from previous projects: "Working with Daniel was one of the best experiences I've ever had with a program developer. 5 other freelancers gave up on this job and Daniel put in the work to understand what I've had problems articulating. His intuitiveness and patience when it comes to extracting abstract ideas and translating it into programming is both admirable second to none. He went above and beyond and I am eternally thankful for his skill and intelligence." "Daniel, once again, did not fail to deliver excellent quality, in a satisfactory amount of time, for a very reasonable price. Most places or people you can request two of those qualities (Good Quality, Good price, fast time), but with Daniel the standard is all three every time. Highest marks of recommendation for Daniel!" "Dan went above & beyond to assist me with completing my project. I can honestly say in all of my years of working with upwork Daniel has been the best, most professional & accommodating freelancer that I have worked with." "I came into this somewhat jaded as a short lived freelancer ghosted me on this project (they got in over their head and couldn't deliver) and was a bit weary of trying this again. But Daniel had clear intentions, great communication, and was a pro from the beginning. Once we discussed the project and hammered out the details, he was off! In a matter of a day or two he had the work 75% done, with the project being completed in under a few days! I couldn't have asked for a better product, it works perfectly and does exactly what I needed it to do. Amazing guy, and amazing work. HIRE HIM IMMEDIATELY!" "Daniel is super professional, and an Excel genius! I truly beleive he knows more about excel that the developers that created excel. Our project came out perfect, and Daniel went over and beyond to make the workbook project perfect. He has proficient knowledge." "Daniel showed up in a bind and made a complex and necessary schedule for my client that was a years long project in the hundreds of thousands in budget. Very urgent and he got it done for me last minute when my plate was too full. We used it and it worked like a dream. Great spirit and helpful and thorough. Would use again for all my spreadsheet PM needs! Thank you!"
