Who it is for
Developers and analysts handling semi-structured text that needs turning into fields.
Key-Value Pair Extractor
Deterministic extraction of labeled fields from text
Overview
What Key-Value Pair Extractor does
This app takes raw text and returns the key-value pairs that are explicitly written in it. Field-like lines are what it recognizes, whichever separator is used: a colon after a label, an equals sign, or a dash.
Output includes the pairs it found, a record of values that are missing, and structured errors where parsing fails.
The limits are stated plainly. Behavior is deterministic and read-only. It does not summarize, rename keys, guess at absent values, check facts, give advice, reach outside data, or take any action elsewhere. The example prompts cover a straightforward extraction, a mixed-format case, and text with one value left blank.
What stands out
The record is unusually explicit about what the app refuses to do, including inference and any external action.

Where Key-Value Pair Extractor is listed
Key-Value Pair 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.

This is an independent catalogue entry compiled by Node8 from Key-Value Pair Extractor's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Beike Yan, and inclusion here is not an endorsement.
