VBA Development
Custom VBA and macro development for Excel, Word, Outlook, and Access, plus modernization of ageing projects and migration to Office Scripts or Office.js where cross-platform or cloud runs are needed.
VBA Development Overview
Our VBA development work covers three things: building custom macros from scratch, modernizing projects that have quietly grown fragile, and migrating to Office Scripts or Office.js when the browser or cloud gets involved. VBA is still a supported part of desktop Office, and Microsoft has announced no end-of-life for it as of 2026, so this is about fit rather than replacement. It runs on Windows and Mac desktop apps but not in Office on the web, which is the line we help teams plan around. Where automation needs to reach outside the workbook, we connect it through a proper API integration instead of brittle glue, and we keep your day-to-day Excel automation fast and dependable while any modernization happens.
A healthcare billing team called after a Windows update broke their oldest Excel macro overnight. The culprit was the phase-out of VBScript: their code leaned on the RegExp object and a couple of external .vbs helper calls that no longer resolved. We moved them to Office build 2508, where RegExp is available natively, rewrote the external calls in pure VBA, and cleaned up the references. While we were in there, we signed and packaged the workbooks so the red Mark-of-the-Web banner stopped blocking macros that arrived by email. Nothing about the daily routine changed for the billing clerks; the automation just stopped surprising them.
Most teams do not need to move off VBA, and we will say so when staying is the right call. VBA still covers more of desktop Excel than the newer tools do. Office Scripts, Power Automate, Python in Excel, and Office Add-ins are the modern paths Microsoft points to, and each one earns its place only where it beats VBA on something concrete, usually cross-platform reach or a cloud-triggered run. We split a workflow by responsibility and move only the parts that gain from it, so you are never rewriting working code for its own sake. Finance, healthcare, logistics, and manufacturing teams still lean on VBA every day, and our job as Microsoft 365 add-in specialists is to keep it reliable, secure, and ready for whatever platform change comes next.
