Removing Routine from Your Schedule with Excel Automation 😎

Well, our journey through Excel is coming to an end. This week we'll wrap it up with a big article and a cheat sheet for practice.

But for now, let's discuss the goldmine for the lazy 🤔

It was announced in 1993. And it still feeds analysts in half of Russian corporations. We're talking about macros.

Macro - a VBA script that automates routine tasks: data cleaning, report building, mailing, document generation. Everything is local. No internet required.

What macros can do:
1️⃣ Clean a 1C export in 8 seconds instead of 40 minutes manually: empty rows, spaces, crooked dates, codes → normal names
2️⃣ Compile a summary report from dozens of regional files: the macro itself goes through folders, grabs data, merges, calculates totals
3️⃣ Send PDFs via Outlook to a list of recipients - open, click, go get coffee
4️⃣ Generate hundreds of invoices/acts from a template: loop through rows = file for each counterparty
5️⃣ Build a mini-dashboard for the sales department: summary by managers, top performers and laggards, PDF to folder

Why do you need this? 🤔
We optimize: half a day of manual work, human errors, "oops, I forgot field X".
We get: 2–3 minutes of machine work, predictable result every time.

Why in Russia you can't do without VBA at all

In government agencies, banks, defense industry, manufacturing - stations are physically disconnected from the internet. Office Scripts, Power Automate, Copilot - they don't work without the cloud at all.

VBA is the only built-in automation method in such environments. No IT department needed. Access approvals, RPA licenses? Forget it.

Fact: Our dear Federal Tax Service with 120,000 workstations lived on macros for years as the main way to kill routine. They started transitioning to RPA only in 2025, because they needed browser work and integration with additional programs.

Where the pitfalls are 🤦‍♂️

1️⃣ Hardcoded ranges: recorded a macro for A1:F100, a month later data goes to row 500 - the code doesn't process the new data, and you're sure everything is fine
2️⃣ Binding to ActiveSheet: run from another workbook - it crashes or calculates incorrectly
3️⃣ No error handling: without Option Explicit and On Error, the code breaks in production out of nowhere
4️⃣ Excel/Windows updates: updates break old macros - from freezes to errors on simple operations

We fix with dynamic ranges, explicit sheet references, error handling, and version documentation (Yes, the one nobody ever wants to maintain).
This resolves dialogues like:
— "Everything broke, fix it urgently"
— "What do you want, it works for me. You have wrong settings"

An analyst with VBA in a closed environment = a person who has more than half of the workday free for coffee and jokes with colleagues. Or maybe for creating a brilliant report… Just don't brag too much about such automation, or the boss will load you with extra work 😂

Do you have routine actions in your practice that repeat endlessly and could be handled with macros?
