Excel Macro (VBA) Development

VBA (Visual Basic for Applications) is a programming language built into Excel that lets you automate repetitive tasks. It takes the hours you’d spend copy-pasting, applying the same formula to fifty rows, or opening and checking files one by one, and reduces them to a single button click.

I write VBA using AI-assisted tools — this lets the work move faster and with fewer errors. But confirming the macro actually works correctly matters more than generating the code; I test every macro against your real data, I don’t just say “it should work.”

Which Jobs Are a Good Fit for a Macro?

Tasks with a clear rule that follow the same steps every time are a good fit for a macro: cleaning up data that arrives in a specific format, merging multiple tabs into one table, color-coding or filtering rows based on specific conditions, auto-filling a report template.

Tasks that require a different judgment call each time, ones that depend on human interpretation, aren’t a good fit for a macro. A macro applies rules, it doesn’t make decisions — getting this distinction clear upfront is the key to setting the right expectations.

The Process: You Describe It, I Write It

You just need to walk me through what you’re doing, step by step — a screen recording, a sample file, or a simple explanation all work. I turn that into VBA code, test it against real data, and deliver it once I’m confident it works.

Along with delivery, I also give you a short video walkthrough: how to run the macro, when to use it, and where to look first if something goes wrong. The goal is that you’re not dependent on me after delivery.

The Limits of a Macro

If the structure of the source file (column order, sheet names) changes often, the macro becomes fragile — it may need a small update every time something changes. Macros can also be blocked in some corporate environments due to security policies; it’s worth checking that upfront.

For very large data volumes or work that needs integration with multiple systems, I might recommend a Python script or broader automation instead of VBA. Picking the right tool for the size of the job matters.

How do we start? We begin with a free 20–30 minute intro call. We talk about what you want and what’s realistic. If it looks like a fit, I send you the scope and price in writing, then we start. You can reach me through the contact page.

Frequently Asked Questions

I don’t know VBA at all — can I still use this?

Yes, you don’t need to know code to use the macro — usually clicking a button is enough. I write the code and show you how to run it with a video.

Will the macro break my file?

I work on a test copy before delivery, I don’t touch your original file. I also build simple safeguards into the macro that stop the process if unexpected data shows up, so nothing changes in your file that you didn’t want.

Does the macro work on every version of Excel?

Mostly yes, but there can be small differences in certain functions between the Mac and Windows versions. I ask which Excel version you’re using upfront and write it accordingly.

Should I get a macro built, or go for full automation?

For work that stays within a single file and is run by one person, a macro is usually enough and faster to build. For work that merges multiple sources or needs to run on a schedule or in the cloud, broader automation can be a better fit.
