What Is VBA File Merging?

VBA (Visual Basic for Applications) allows Excel to perform automated operations. When you learn how to merge multiple Excel files into one workbook using VBA, you are essentially creating a macro that:

1. Reads all Excel files in a folder
2. Opens them one by one
3. Copies each sheet
4. Pastes them into your main workbook
5. Renames or organizes them automatically

The result?
A clean, fully combined workbook created with just one click.
