Option Explicit forces the programmer to declare all variables before using them. It helps avoid spelling mistakes and improves code reliability.

Variables are declared using the Dim statement.

• Sub Procedure: Performs actions but does not return a value.
• Function Procedure: Performs calculations and returns a value.

The Range object represents a cell or a group of cells in Excel.

• Range: Refers to cells using Excel-style notation like A1.
• Cells: Refers to cells using row and column numbers like Cells(1,1).

Last Used Row in Excel VBA refers to the row number of the last cell that contains data in a worksheet. It is commonly used to determine the end of a dataset for looping, inserting, updating, or processing records dynamically.

Loops are used to repeat a block of code multiple times. Common loops in VBA are For Next, Do While, and For Each.

Error handling allows the program to manage runtime errors gracefully without crashing.
