If you run a sales team, an agency, or a lean ops crew, Excel macros are probably the most underused lever in your stack. A single VBA procedure can clean a messy CSV, generate board‑ready charts, update your CRM export, and even email a PDF report — all in seconds. Yet most teams avoid VBA because it feels brittle: security prompts, hidden Developer tabs, and the fear of breaking a workbook that “just works.”
Learning how to run VBA code properly — enabling the Developer tab, setting macro security, storing code in the right module, and triggering it with buttons or events — turns Excel into an execution engine you can trust. Now layer Google Sheets on top as a live data front-end, and you have a powerful pipeline.
This is exactly where an AI computer agent shines. Instead of you babysitting every macro, the agent can open workbooks, refresh connections, run VBA, sync to Google Sheets, and handle failures. You design the rules; the agent does the clicking, checking, and rerunning — so your reports ship on time even when you’re in meetings.
Before you let an AI agent touch your workbooks, you need a solid manual playbook. Here are the most reliable ways to run VBA today.
.xlsm).CleanLeadData).Best for: occasional runs, debugging.
Sub you want to run.Best for: development, quick tests, stepping through code with F8.
Now anyone can run your macro safely with one click.
Best for: non-technical teammates, recurring workflows.
d for daily report).Now Ctrl + d (Windows) or Option + Command + d (Mac) runs your macro, as long as the workbook is open.
Best for: power users running the same macro all day.
Sometimes you want reports or cleanup to run the moment a file opens.
Private Sub Workbook_Open()
Call CleanLeadData
End Sub
Workbook_Open.(Microsoft doc: https://support.microsoft.com/en-us/topic/automatically-run-a-macro-when-opening-a-workbook-1e55959b-e077-4c88-a696-c3017600db44)
Pros: fully hands‑off once opened.
Cons: can confuse users if something breaks on open.
Now imagine you’re a marketer pulling ad spend from Google Sheets and formatting it in Excel for finance. You can add a thin automation layer without writing more VBA.
Now a non‑technical teammate can hit a button and redo your entire pipeline.

VBA doesn’t run inside Google Sheets, but Sheets can be your live data front‑end.
Docs:
Pros: Sheets stays collaborative; Excel does heavy lifting.
Cons: Some manual export/import unless automated with tools.
Use schedulers like Power Automate, Make, or Zapier to orchestrate when files are opened or refreshed. While they can’t always run VBA directly, they can:
Manual methods are fine until you need to do them every hour, across tens of files, for different clients. This is where an AI computer agent like Simular becomes your operations teammate.
What it does:
.xlsm workbook.CleanLeadData, and runs it.
Pros:
Cons:
For agencies or sales ops teams, real power comes from chaining Google Sheets and Excel.
A Simular agent can:
Pros:
Cons:
If you’re ready for production-grade scale:
Because Simular is designed for workflows with thousands to millions of steps, it can reliably:
Pros:
Cons:
Once you’ve mastered the manual techniques, letting an AI agent orchestrate them turns VBA from a fragile script into a dependable engine behind your Google Sheets and Excel workflows.

To run VBA safely, start by enabling the Developer tab. In Excel, go to File > Options > Customize Ribbon, then check Developer under Main Tabs and click OK. Next, open a macro-enabled workbook (.xlsm). If your file is .xlsx, resave it as .xlsm so it can store code.
Before running anything, configure macro security: on the Developer tab, click Macro Security. Under Macro Settings, choose either “Disable all macros with notification” (recommended) or “Disable all macros except digitally signed macros” for stricter control. Click OK.
Now press Alt + F11 to open the Visual Basic Editor and confirm your macro exists inside a standard Module or ThisWorkbook. Return to Excel, click Developer > Macros, pick the macro name, then click Run. Test on a copy of your workbook first, and keep backups in version control or cloud storage. This way you can take advantage of automation while staying safe and reversible.
If your macro isn’t firing on open, it’s almost always about placement or security. Auto‑run logic must live in the ThisWorkbook module using the exact event name Workbook_Open (or Auto_Open in a standard module, which is legacy). In the Visual Basic Editor, expand VBAProject, double‑click ThisWorkbook, and add:
Private Sub Workbook_Open()
Call YourMacroName
End Sub
Save the workbook as .xlsm, close Excel completely, then reopen the file. When prompted, click Enable Content to allow macros. If macros are disabled by policy, you may need your IT team to relax settings or digitally sign your code.
Also ensure no runtime errors occur silently. Temporarily add a MsgBox "Opened" line inside Workbook_Open to confirm the event triggers. If the message appears but your main macro doesn’t complete, step through it with F8 to locate the failing line (often a missing sheet name, named range, or external file). Fix those references and retest.
To make macros easy for non‑technical teammates, wire them to buttons or keyboard shortcuts.
For a button on the sheet:
For a keyboard shortcut:
r). This maps Ctrl + r (or Option + Command + r on Mac) to your macro.Avoid overriding common shortcuts like Ctrl + Z or Ctrl + C. Test everything on a copy of your workbook, then teach your team: “Click this button after you paste new data, and Excel will do the rest.”
VBA itself only runs inside Excel, but Google Sheets can be the collaborative front‑end feeding your VBA engine. A common pattern for sales and marketing teams is: collect or edit data in Sheets, then push it into Excel for heavy‑duty automation.
One simple workflow:
For more automation, you can combine Apps Script in Sheets with VBA in Excel, or orchestrate the whole loop using an AI agent that clicks through the browser and desktop exactly the way a human would.
An AI agent like Simular becomes a virtual analyst who never gets tired of opening workbooks and pressing Run. Instead of you remembering to refresh each client’s Excel file, the agent follows a clear script of actions you define once.
In practice, that might look like this: when a new CSV lands in cloud storage or a Google Sheet updates, a webhook triggers your Simular Pro agent. The agent opens Excel, enables macros if prompted, loads the correct .xlsm template, runs your VBA routines (data cleanup, KPI calculation, chart updates), exports outputs (PDF decks, XLSX summaries), and uploads them to shared folders or back into Google Sheets.
Because Simular logs every action as transparent, inspectable steps, ops leaders can audit what ran and when. This turns fragile, person‑dependent macro processes into scalable workflows that support dozens of clients or regions — without hiring a parallel team just to babysit Excel.
