SCD Visualizer is a dual-stack tool for parsing, validating, and visualising IEC 61850 SCD/SCL substation configuration files.
It consists of:
- A React/TypeScript browser application (Vite) for interactive exploration and visual analysis
- A Python CLI for headless validation and CSV/report export in CI/CD pipelines

- Parses
.scd,.cid,.icd,.iid,.ssd, and.xmlSCL files - Runs 26 structural validation checks (LNET_001–018 + IEC_001–008) plus full XSD schema validation
- Visualises IED topology, GOOSE/SV/Report subscriptions, network traffic, and Single Line Diagrams
- Compares two versions of a file and highlights added/modified/removed elements
- Exports results to CSV, Excel, or Landsnet compliance JSON
- Supports Landsnet-specific naming and VLAN conventions via a configurable
