YAML Tools

The ultimate YAML toolkit for developers. Visualize, validate, convert, and generate code - all in one powerful, beautifully designed iOS app.

YAML Tools is the professional-grade YAML utility built for developers who demand speed, precision, and versatility. Whether you're editing Kubernetes configs, debugging CI/CD pipelines, or generating type-safe model classes, YAML Tools handles it all natively on iPhone and iPad.

Visualize & Explore
Dive into your YAML with an interactive Tree View and path-based querying. Use the Table View to inspect sequences like a spreadsheet. Rainbow column highlighting makes CSV/TSV output instantly readable.

Format & Transform
Prettify nested structures with smart indentation or strip whitespace with the Minify engine. Convert YAML to JSON, XML, CSV, TSV, TOML, HTML, Markdown, Base64, and more instantly.

Generate Production-Ready Code
Export type-safe model classes for Dart, Swift, Kotlin, Java, Python, TypeScript, and C# with intelligent property singularization and pluralization. Stop writing boilerplate, YAML Tools writes it for you.

Validate with Confidence
Auto-generate JSON Schema from any YAML document, then validate payloads against it in real time. Catch structural errors before they reach production.

Built for iOS
A dedicated YAML syntax keyboard overlay, native Document Picker integration, and background processing keep the experience fast and fluid, even on large configuration files.

Find & Replace - A built-in find-and-replace bar (⌘F)

Table View Revamp - Content-aware auto-sizing columns, theme-aware, and a view state that remembers your filters, sort, and frozen columns across edits.

Compare Mode - Diff any two documents side by side with color-coded additions, deletions, and edits, deep nested-object comparison, and one-tap navigation between changes.

Tree View Revamp - Cleaner, calmer rows that stay put when selected, GitHub-style type colors, a focused-node accent, and a streamlined inspector that keeps every action one tap away.
