Joiner is a lightweight Node‑compatible library and CLI tool that performs SQL‑style left joins on JSON‑based datasets—including plain JSON, CSV/TSV/DBF converted to objects, and GeoJSON feature properties. It returns the merged data together with a detailed join‑success report, making it useful for developers, data analysts, and GIS specialists who need to verify and troubleshoot dataset merges across multiple formats.
