Excel VBA Macro Generator — illustrative example

INPUT
Excel desktop VBA. The macro is stored in the target workbook. Worksheet name: Orders. Format only A1:D1 in bold. No other formatting changes.

RESULT
Sub FormatOrdersHeader()
    Dim target As Worksheet
    Set target = ThisWorkbook.Worksheets("Orders")
    target.Range("A1:D1").Font.Bold = True
End Sub

Scope: the workbook containing the macro, Orders!A1:D1. A missing Orders sheet causes an error before formatting. Test in a copy; no Excel execution is claimed.

REVIEW
A macro should state the workbook assumptions and affected range. Avoid broad deletion or formatting changes without an explicit boundary.

This is a teaching example, not a live execution record.
