Turn invoices and receipts into an Excel workbook with totals and error checks.
Takes invoice, bill or receipt details and builds an .xlsx workbook with a row per invoice and per line item, plus checks for arithmetic errors, missing fields and duplicates. Muse can also verify invoices without creating a file, or fetch a blank template for expenses, landlord accounts or CIS costs.
Try asking Muse: "Put these October supplier invoices into a spreadsheet and flag any that do not add up or look like duplicates."

Invoices to Spreadsheets is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
