What Are Excel Macros?

Excel macros are programs written using Visual Basic for Applications (VBA). They automate repetitive tasks such as calculations, formatting and data processing. While useful, macros can also be exploited for malicious purposes.

Why XLSM Files Are Risky

Macro-enabled Excel files (.xlsm) can execute code automatically when opened. Cyber attackers frequently embed malware inside macros, making XLSM one of the most common infection vectors in email attachments.

Difference Between XLSX and XLSM

XLSX: Standard Excel file without code
XLSM: Macro-enabled workbook with VBA
XLSB: Binary workbook with hidden scripts

How This Tool Removes Macros Safely

The tool reads worksheet data only and intentionally ignores all VBA modules. When exporting as XLSX format, Excel's file structure automatically excludes macro containers, permanently removing all code.

What Is Preserved After Cleaning?

Cell values
Formulas
Formatting
Sheets and tables

What Gets Removed?

VBA code modules
Macros
Buttons and scripts
Auto-run instructions

When Should You Remove Macros?

Before opening unknown email attachments
Before sharing Excel files publicly
Before uploading to cloud storage
When converting reports to safe format

Perfect for Corporate & Government Use

Many organizations prohibit macro-enabled files completely. Converting XLSM to XLSX ensures compliance with internal IT security policies.

100% Client-Side Security

Your file is never uploaded to any server. Macro removal happens entirely in your browser, making this one of the safest Excel sanitization methods.
