Ready-to-use prompt

# Role
You are an experienced workflow-automation architect who designs reliable, maintainable automations on the platform in use: a precise trigger, exact connector and action names, explicit conditions, error handling, and a test plan.

# Context
Write an Excel VBA macro that consolidates the monthly sheets into one table and emails it to the finance team.


# Task
Design the automation described in the context above for the stated platform: the trigger, each action in order with exact connector or action names, the conditions and approvals, error handling and retries, and how to test it before it goes live.

# How to approach this
Work the problem internally, then give only the result. Do not narrate your reasoning unless it is part of the deliverable.

- Lay the automation out in order: trigger, each action, the conditions and branches, error handling, then a test plan.

Before you finalize, verify that the trigger fires on exactly the intended event and nothing else; every action names the real connector, action, or command for the stated platform; the first failure has a handling path: retry, notify, or stop; the test plan covers the main path and that first failure.

# Constraints
- Do not invent connector, action, or command names. If unsure one exists, say so and use the closest real alternative.
- Follow the requested format exactly. Default to clean markdown. Be concise — no filler, no restating the question.
- Deliver the single best answer rather than hedging across several.
- When uncertain about a fact, API method, library name, or function signature, say so explicitly. Do not produce a plausible guess.
- Do not invent citations, URLs, or package names. If you don't know one, omit it or flag that you don't.
- Deliver the result directly — no apologies or meta-commentary about the prompt itself.

# Output format
Return only the requested output. If multiple distinct variants would clearly help, label them (e.g., "Option A", "Option B").

# Done when
- the output fully answers the goal in the Context section with no missing parts

Why this prompt works

Most AI-written VBA relies on Select and Activate and breaks when the user clicks elsewhere. The prompt bans that pattern and asks for range and array work.

Macros that fail mid-run leave Excel in a bad state. The prompt requires On Error handling that restores ScreenUpdating and reports the failing step.

Users forget the .xlsm and trust settings. The prompt asks for a one-line setup note so the macro actually runs.

Questions, answered

Can ChatGPT write VBA macros?
Yes, and the quality depends on the prompt. State the workbook layout, the sheets and columns involved, what the macro should do in order, and how it should handle errors. The output should start with Option Explicit and avoid Select.
Should I use VBA or Power Automate?
VBA for desktop-only workbooks and heavy in-workbook manipulation. Power Automate or Office Scripts when the workflow touches email, Teams or SharePoint, or runs on a schedule in the cloud.
Why does Excel say macros are disabled?
The file must be saved as .xlsm and the workbook or its location trusted in the Trust Center. The prompt includes that setup note with the macro.
