Workflow
Five-step validation loop
Built for repeated filing QA runs, not one-off checks.
1. Upload
Submit `.xml`, `.html`, or `.zip` artifacts up to 50MB.
2. Validate
Worker executes Arelle asynchronously with tracked job state.
3. Normalize
Messages map into a stable issue model with references and location hints.
4. Diagnose
Use severity counters, filters, issue detail, document view, and taxonomy insights.
5. Compare
Diff runs by issue and document changes to isolate meaningful regressions.
Capabilities
Operational features for filing QA teams
Human-friendly issue triage
Grouped counters, deterministic sorting, searchable fields, and master-detail issue review.
Run comparison and document diffs
Compare completed runs to classify new, resolved, persisting, and changed issues with companion side-by-side document blocks.
Taxonomy insight detection
Local deterministic heuristics flag suspicious extension patterns separately from validation issues.
Portable outputs
Export normalized issues plus job metadata for downstream QA workflows and tracking.
