Master Visual Basic and Excel for Efficient Automation

1. Macros

Macros are scripts that perform specific actions in Excel. With VBA, you can record or write macros to execute tasks with a single click.

Example: Automating Data Entry

2. Custom Functions

VBA allows the creation of user-defined functions to extend Excel's default capabilities.

Example: Calculating Compound Interest

3. Data Connectivity

With VBA, Excel can connect to external data sources like databases, APIs, or web services.

4. Event-Driven Programming

VBA supports event-driven programming, enabling scripts to run automatically when specific events occur (e.g., opening a workbook).
