Who it is for
Accounts payable staff and developers who need invoice contents turned into fields before they go anywhere else.
Invoice Field Extractor
Structured field extraction from invoice text
Overview
What Invoice Field Extractor does
Invoice Field Extractor reads invoice text and returns it as structured data. The fields it pulls include the invoice number, both parties, relevant dates, line items, subtotal, tax, total, currency, billing address, and payment terms.
It also reports on gaps. Fields that should be present but are not get flagged, as do errors found in the document, which makes the output a validation pass as well as a parse.
The boundaries are stated at length. The app is read-only. It will not approve or pay an invoice, give tax or accounting advice, email anyone, contact a supplier, or write to any external system. One of the listed example prompts asks it to pay an invoice, which it declines to do.
What stands out
The refusal list is part of the product description, down to a sample prompt the app is designed to turn down.

Where Invoice Field Extractor is listed
Invoice Field Extractor is listed in the ChatGPT apps directory only. Beike Yan has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
