Hello, and thank you for taking the time to read my Profile. I'm Tony, The Excel (and Google Sheets) Expert. Excel & Google Sheets Expert | 30+ Years Experience | Practical, Powerful, and User-Friendly Solutions | Data Input Systems | VBA Macros | Google Scripts | Dashboards | Raw Data Analysis & Much More. Whatever you're looking to do, if it's in Excel or Google Sheets, I can make it happen. Please feel free to contact me about any type of project you need help with, be it a new project, help fixing an existing document, improving designs, adding page and document protection and security, or anything else you might need. Whether it's a full system build/rebuild or just a small fix or change, I'd love to hear from you. I’ve been creating, designing, fixing, and editing Excel documents for over 30 years. In that time, I’ve created, developed, invented, and implemented more than 10,000 spreadsheets and systems, from simple invoices for building contractors and small businesses to complex documents that track income, expenditure, time, performance, CRM's that help you keep track of your customers needs and of course staff Salarys, Bonuses, Wages, In fact anything you can think of I've probably built, and more. I believe a well-designed document will not only look better, but also be easier to understand, operate, and maintain. I have a strong eye for design and can, if needed, make the document feel like a standalone program, not just a spreadsheet. and can password-protect certain parts/tabs so only those with the permissions to do so can edit them. I specialise in turning complicated problems into simple, elegant solutions, and I’ve built a reputation for creating spreadsheets that are functional, intuitive, and user-friendly, even for non-technical users. I have added some screenshots of the many documents I've created over the years to hopefully give you an idea of the standard of work I create. It's hard to translate all the details of a working document into just a screenshot, but hopefully it will give you an idea at least, so please check out my Images below. A summary of just some (But every job is different so I couldn't list them all) of the types of work I do. • Create Excel & Google Sheets tools that make your day easier, not harder • VBA macros & advanced formulas that automate repetitive work • Dashboards & interactive reports that surface exactly what matters • Automated invoicing, emailing, and data input systems • Google Sheets dashboards, including App Script for web-based solutions • User-friendly staff entry tools for hours, sales, capacity, performance, etc. • Dynamic charts, slicers, pivot tables, and SharePoint integration • Publish-to-web tools and auto-updating sheets for real-time access • Interface design that adapts to your workflow, not the other way around About Me • I’m friendly and easy to work with. You explain what you need, and I'll make it happen • I’m fluent in VBA, formulas, advanced formulas, dashboard & charts design (including slicers etc), and more • I’ve worked with clients worldwide, mainly in the USA and Australia and the UK, where I'm based/from, but happy to work with anyone, anywhere • I’m used to Zoom, Teams, even Skype (yep, some people still use Skype! lol) • I’ll work around your schedule and time zone, time differences never get in the way • I work fast and efficiently. When people need a solution ASAP, they come to me • Whether it’s a 100,000-line database or a simple automation fix or anything in between, if it's Excel or Google Sheets it's my area of expertise. Whatever you need, if Excel or Google Sheets is the platform, I’m the expert you’re looking for. Please feel free to reach out. I’m always happy to talk about new projects and look forward to building a solution that works for you. Kindest Regards Tony :-)
