Developer Code & Schema Validation Tools
Audit configuration syntax and dataset schemas locally. Our in-browser AST engines process files entirely in-memory with zero server transmissions.
Markdown File Validator
Validate Markdown and MDX documents for structural hierarchies, heading levels, image alt attributes, and link syntax rules.
CSV & Dataset Validator
Audit CSV and tabular datasets for schema compliance, duplicate primary keys, value type parity, and null value thresholds.
YAML Schema & Syntax Validator
Audit YAML files for syntax compliance, duplicate keys, unquoted Norway boolean keywords, and schema constraints.
GeoJSON Spatial Contract Linter
Audit GeoJSON files for self-intersecting geometries, winding order directions, coordinate snaps, antimeridian gaps, and bbox limits.
JSON & JSON Schema Validator
Audit JSON documents for syntax validation, duplicate keys, numeric precision loss, credentials exposure, and JSON Schema presets.
Mermaid Diagram Syntax & Semantic Validator
Lint Mermaid.js diagrams for syntax errors, circular dependencies, disconnected nodes, and accessibility issues. Scans .mermaid, .md, and .mdx files.
Excel (XLSX) Schema Validator
Audit Excel spreadsheets for schema compliance, sheet tab existence, column datatypes, cell formula errors, and primary key uniqueness.
.env File Validator & Secret Risk Scorer
Audit environment variable configurations for syntax issues, trailing whitespaces, duplicate keys, exposed secrets, variable interpolation, and example template sync drift.
TOML Schema & Syntax Validator
Audit TOML config files for syntax compliance, duplicate keys, key casing styles, Windows backslash escapes, unquoted boolean warnings, credentials leaks, and schema preset requirements.
i18n Locale File Validator & Comparison Workspace
Audit GNU Gettext PO, XLIFF, and Flutter ARB localization files. Detect missing keys, broken HTML tags, placeholder mismatches, formatting drift, and fuzzy translations side-by-side.
Developer API SDK
Automate syntax validations in build runners
Integrate our structured YAML syntax, CSV schema, and Markdown heading compliance checkers directly into your CI/CD pipelines or local CLI pre-commit hooks.
