Connect your .docx, .doc, .odt documents and .xlsx, .xlsm, .xlsb, .xls, .ods workbooks to Muse. Read paragraphs and cells, propose edits with preview, apply changes, and download the edited file. Preserves formatting, comments, tracked changes, VBA macros and Power Query.

Example request: "Open my Excel budget spreadsheet, update the Q4 revenue numbers, and save me a copy with the changes."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use SumOffice to help me. It is a free service with an MCP server at https://view.sumoffice.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- document_open: Open one of the demo files by name: documents footnotes, comments, forms, rtl, wild-horse, workshop, offer, tools; workbooks workbook, functions, macros, queries, gep, vba-web, sqlite, order-desk, onrr, cashflow, pivot, chart, notes, check, xtools. Default is footnotes. For your 
- document_open_file: Open YOUR file in a private editor cabin for this session: a .docx/.doc/.odt document or an .xlsx/.xlsm/.xlsb/.xls/.ods workbook, up to 50 MB. Give exactly one of: url (https link the server can fetch), base64 (file bytes; then name with the extension is required). Nothing in the
- document_describe: Name, pages, paragraphs, words, number of comments and tracked changes, whether track changes is on. For documents; call first.
- document_read: Paragraph text as a window: from = index of the first paragraph (0-based), count = how many (max 40). The answer carries next — where to continue, null at the end. A missing paragraph is a refusal, not an invention.
- document_find: Paragraphs containing the text (case-insensitive), with snippets around the match.
- document_comments: Comments (author, text, anchor, resolved) and tracked changes — up to 50.
- document_propose_replacement: Propose the full new text of one paragraph (paragraph_index from document_read). Nothing changes yet: the editor core builds the change on a copy and returns before/after plus checks (numbers, dates, links kept). Then call document_apply with the proposal_id. Read the paragraph f
- document_apply: Apply a proposal from document_propose_replacement to the document in this session's cabin (not to your original file). Stale proposal (the document moved on) is refused by the engine — propose again. Repeating an applied proposal is a no-op.
- sheet_describe: Workbook overview: every sheet tab with its used range, the current revision, and the header row of the sheet that is open. Call this first, then pass the tab name you need as "sheet" to sheet_read and sheet_find.
- sheet_read: Read a rectangular range like A1:F20 (max 60 rows × 26 columns): values and formulas. Empty cells are omitted. ALWAYS pass "sheet" with the exact tab name when the workbook has more than one sheet — without it you read whichever sheet happens to be open, and the answer will quiet
- sheet_find: Find cells whose value or formula contains the text (case-insensitive) in the used range of a sheet. ALWAYS pass "sheet" with the exact tab name when the workbook has more than one sheet: without it only the sheet that happens to be open is searched.
- macro_list: List VBA modules and runnable macros (entry points) in this workbook with their route and blockers. Runs nothing.
- macro_read_source: Read the source text of one procedure (module + procedure name from macro_list). Read-only; runs nothing.
- macro_plan: Plan a macro run without running it: route, whether the engine can run it natively, blockers, instruction budget.
- query_list: List Power Query queries in this workbook: names, step chain, load target, connections. Reads only; refreshes nothing.
- query_explain: Explain one Power Query query by name: its steps in order, where it loads, its connection. Reads only; refreshes nothing.
- workbook_inspect: Map the whole application model of this workbook in one call: sheets; VBA modules, procedures, which can run here and which are blocked and why; event handlers; external objects (CreateObject) and Windows API (Declare) dependencies; project references; Power Query queries; data c
- sheet_propose_edits: Propose new contents for up to 20 cells (formulas like =SUM(B2:B9), or numbers/text). Nothing changes in the workbook: the engine previews the edits on the current revision and reports what would change and whether errors appear; the person decides whether to apply. Read the cell
- sheet_apply: Apply a proposal from sheet_propose_edits to the workbook in this session's cabin (not to your original file); the engine recalculates. Refused if the workbook revision moved on since the proposal — propose again. Repeating an applied proposal is a no-op.
- document_save_copy: Write the document or workbook as it is now in this session's cabin (after applied proposals) to a copy and return a download link valid for 24 hours. Your original file is never touched. A workbook with macros comes back as .xlsm with the VBA project intact; a document keeps its
- document_export_pdf: Lay out the document as it is now in this session's cabin (after applied proposals, or as opened) and return a PDF download link valid for 24 hours, plus the page count. Documents only; for workbooks use document_save_copy.
