# 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 Office Script that cleans a raw export sheet, removes duplicate rows, and builds a summary table on a new sheet. # 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 Think through the problem step by step before answering. Work the hard parts out explicitly, then give a clear final answer. Let the difficulty of the task set how much reasoning is needed — don't pad the easy steps. - 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. - Use clean, professional formatting that pastes cleanly into Word, Outlook, and Excel. Prefer tables and numbered steps for anything structured. - Deliver one finished, office-ready result rather than a set of options. - Keep the tone professional and workplace-appropriate unless the prompt says otherwise. - For spreadsheet or document tasks, give the exact formula, steps, or text — never a vague description of what to do. - 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

Start the interview →Why this prompt works
Office Scripts use the ExcelScript API, not VBA and not Node, so the prompt pins the API and asks for range and array operations, which is where performance and correctness live.
Scripts cannot reach email, Teams or the web on their own. The prompt says when to hand off to a Power Automate flow that runs the script.
Sheet and table names are the most common failure, so the prompt requires them to be checked before any write.
Using this prompt in Copilot
For office script excel, Copilot is a strong choice — it's especially good at Office-ready output you can finish in Word, Outlook, and Excel. Promptivo formats this prompt the way Copilot works best: office-ready output that pastes cleanly into Word, Outlook, and Excel, with tables and numbered steps.
Paste it into Microsoft Copilot or the Microsoft 365 side-panel, then replace any bracketed details with your own. Copilot generalizes when it is under-fed, so keep the bracketed context specific and it will stay grounded in your details.

Questions, answered
- What is the difference between an Office Script and a VBA macro?
- Office Scripts are TypeScript, run in Excel on the web and desktop, and can be called from Power Automate. VBA runs only in desktop Excel and needs a macro-enabled workbook. Pick Office Scripts for cloud and automation, VBA for desktop-only legacy files.
- Can an Office Script send an email?
- Not by itself. Return the data from the script and let a Power Automate flow send the email or Teams message.
- How do I make an Office Script fast?
- Read a range into an array once, work in memory, and write back once. Avoid per-cell loops and repeated getRange calls. The prompt asks for this pattern.
- Is Copilot good for office script excel?
- Yes. Copilot handles office script excel well thanks to its Office-ready output you can finish in Word, Outlook, and Excel, and Promptivo tunes the prompt to match — office-ready output that pastes cleanly into Word, Outlook, and Excel, with tables and numbered steps. Paste it into Microsoft Copilot or the Microsoft 365 side-panel.
