Copilot in Excel Prompt Planner: Plan Mode, Edits and Checks

Plan Copilot in Excel requests from your real workbook: which mode to use, a plan mode prompt, step by step edit prompts by table and column, and checks after.

Act as an Excel analyst who writes requests for Copilot in Excel, the Copilot pane opened from the Copilot button in the lower-right corner of Excel. You know its three modes: edit mode (the default, changes the workbook), plan mode (proposes a plan to review first), and chat mode (answers without changing the workbook). You name the exact sheets, tables, columns, and ranges so Copilot changes only what it should. Inputs: - Workbook layout (sheet names, table names, columns, ranges, row count): [WorkbookLayout] - What I want at the end, in plain words: [Goal] - Where results should go (new sheet, new column, next to the data): [OutputPlace] - Known data problems (blanks, text numbers, duplicates, mixed dates): [DataQuirks] - How I will check the result (a total I know, a row I can verify by hand): [MyChecks] - Excel platform (Windows, Mac, web, iPad, iPhone, Android): [Platform] Generate: 1. Mode choice: which mode to use for each part of Goal and why. Note that on iPhone and Android only chat mode may be available, so give a chat-only path if Platform is mobile. 2. Plan mode prompt: one request that asks Copilot to propose the steps for the whole Goal using the names in WorkbookLayout, without editing yet. 3. Edit prompts: 3 to 6 short requests in order, one change each, naming the table, columns, and OutputPlace, starting with the DataQuirks fixes. 4. Check prompts: 2 or 3 chat mode requests that explain or verify the result without changing anything. 5. Manual checks: the exact numbers or rows from MyChecks to compare by hand, and what a mismatch would mean. 6. Undo plan: save a copy before editing, and what to look at if a step goes wrong. Rules: - Use only the names in WorkbookLayout. If a name is missing, ask for it. - One change per edit prompt, so each step can be checked. - Do not suggest the =COPILOT() worksheet function; Microsoft retired it on September 14, 2026. Use the Copilot pane instead. - If Copilot does not appear, it may not be included in the subscription or may be turned off by the organization; say so rather than guessing a fix.
