What Is VBA and What Can It Do in Excel?
VBA (Visual Basic for Applications) is Excel’s built-in coding language. It’s been around for decades and is great for automating repetitive tasks.
What Tasks Can VBA Automate in Excel?
- Save and open files
- Format sheets
- Add buttons and dropdowns
- Export data to PDF or CSV
- Trigger actions when the workbook changes
- Send emails from Excel
If you want to start automating tasks and building your own Excel tools, VBA is a great place to begin.

But VBA has two big limitations:
Why Doesn’t VBA Work in Excel Online?
Open a file from Teams, SharePoint, or OneDrive, and it launches in Excel for the web.
Your macros won’t run there.
And most users don’t even realize they’re in the online version—until something breaks.
Why Do IT Departments Block VBA Macros?
Many companies see macro-enabled files (.xlsm) as security risks.
VBA can run hidden scripts that spread malware.
So IT departments often:
- Block all macros by default
- Only allow them from “trusted locations”
- Ban macro files entirely
Even if your VBA works, your colleague may not be able to use it.

What Is Python in Excel and How Does It Work?
Python in Excel lets you use Python code directly inside your spreadsheet—just like a formula.
You don’t need to install anything.
If you’re using Microsoft 365 for Windows, and you have access to the Python integration, you can start using Python in Excel right away. Availability is rolling out gradually.

Why Is Python Built Into Excel Now?
Python is a powerful coding language now built into Excel.
You can use it to clean data, analyze trends, and build custom reports—without leaving your spreadsheet.
It’s especially useful if you:
- Work with large or messy datasets
- Want to group, filter, or reshape data quickly
- Need to run advanced calculations or models
- Build charts that go beyond Excel’s native tools
- Use AI or machine learning (like forecasts or predictions)
You don’t need to be a programmer to benefit.
If you work with data in Excel, Python gives you more power, less clicking, and faster results.
What Can You Do with Python in Excel?
Now, with Python built into Excel, you can:
- Write Python formulas in cells
- Combine Python and Excel formulas in the same workbook
- Use libraries like pandas for fast data filtering and grouping
- Build custom charts with matplotlib or seaborn
What Are the Limitations of Python in Excel?
Python in Excel runs in a secure Microsoft cloud container.
That means:
✅ No setup needed
✅ No risk of local viruses
🚫 No access to your local files
🚫 No internet access
🚫 No control over workbook properties (can’t rename, save, or move sheets)
So it’s great for analysis—but not for automation.
How Does Python in Excel Compare to VBA?
Here’s a side-by-side look at what each tool can do inside Excel:
| Task | VBA | Python in Excel |
|---|---|---|
| Data Cleanup & Processing | ✅ | ✅ |
| Reporting | ✅ | ✅ |
| Custom Functions | ✅ | ✅ |
| Workbook & Worksheet Automation | ✅ | ❌ |
| Style & Cell Formatting | ✅ | ❌ |
| Chart Formatting | ✅ | ✅ |
| Import Data | ✅ | ✅(with Power Query) |
| Export Data | ✅ | ❌ |
| Email Automation | ✅ | ❌ |
| Dropdowns & Checkboxes | ✅ | ✅ |
| Form Controls | ✅ | ❌ |
| Works Online | ❌ | ✅ |
When Should You Use VBA Instead of Python?
Use Excel VBA if your main goal is to:
- Automate Excel tasks
- Save or export files
- Run macros based on user actions (like clicking a button)
But be careful—VBA won’t work online, and some users may be blocked from using it.
When Should You Use Python Instead of VBA?
Use Python in Excel if you:
- Work with large or messy datasets
- Need advanced analysis or custom visuals
- Want to run machine learning or models inside Excel
- Need something that works in Excel Online and passes IT security checks
When Should You Use Office Scripts Instead of VBA or Python?
If you need to automate Excel in the cloud—especially when working in Teams, SharePoint, or OneDrive—consider using Office Scripts.
They’re built for Excel Online, more IT-friendly than VBA, and don’t require macro-enabled files.
While they’re not as advanced as VBA (yet), they’re improving fast and are ideal for basic web-based automation.
