lcpl viewer

LCPL Viewer analyzes LCPL payloads to provide a structured diagnostic and comparison interface for data teams. It accepts a single payload for validation or two payloads for diffs, parsing the content into a graph-like representation and validating against a baseline schema. It then computes metrics such as node count, depth, and type distribution, returning a machine-readable report suitable for automation.
Conceptually, the tool treats LCPL as a tree of labeled nodes and performs rigorous structural checks, identifying orphan nodes, missing relations, and version mismatches. For diffs, it aligns trees and reports insertions, deletions, and moves with precise paths. This separation of concerns—validation, metrics, and diffs—facilitates automation and CI integration.
Who benefits? Development teams, data engineers, content architects, and QA analysts gain visibility into data integrity across projects. Unique value lies in combining structural validation with delta analysis for LCPL, plus batch processing and export options for downstream tooling. Core features include input parsing, version detection, structural validation, metrics reporting, delta analysis, and exportable results (JSON/CSV). Typical use cases cover schema migrations, quality gates in pipelines, and content-model reviews.
