How to use the Excel VBA Macro Generator.
A macro should state the workbook assumptions and affected range. Avoid broad deletion or formatting changes without an explicit boundary.
Make the workflow fit your task.
State the workbook, worksheet and affected range, along with the desired formatting or transformation. Qualify references explicitly and describe expected changes before running the macro on a copy. Avoid using the current selection as an accidental boundary.

- Workbook task and explicit constraints.
- What you get
- VBA draft with backup and execution notes.

Illustrative input and output · a teaching example, not a live WebAct run
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.
Completed example
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.Load this input into the prompt, then copy it to WebAct to try the task. Your result may differ from the illustration.
Decisions and troubleshooting.
How can a macro avoid changing the wrong worksheet?
Reference the intended workbook and sheet explicitly, and check their expected structure before modifying cells.
Why does the macro fail in a workbook opened in the browser?
VBA support depends on the Excel environment. Confirm a compatible desktop workflow and the file format before trying to execute it.
Reference for this workflow.
Try it with your own source.
Replace the example with your material in the task prompt. Keep the requirements you need, then copy the task into WebAct.
