The OCL Mapper: a 200-row lab test mapping project with ranked LOINC candidates and the OCL AI Assistant's rationale for the recommended match

See it in action

Auto-match your rows, then decide with the evidence in front of you

Auto Match every row at once

Run OCL's matching algorithms across your whole spreadsheet and get ranked candidates for each row.

AI recommendations with the reasoning

Not just a score — the OCL AI Assistant says which axis decided the match, and why the alternates lost.

Decide, review, export

Map, propose or exclude each row, then export your decisions in the format you need.
