YAML to Go Converter

Working with YAML data and need Go models fast? YAML supports anchors (&) and aliases (*) for reusable values — this converter resolves them before generating types. This free, browser-based converter parses your YAML and generates clean, production-ready Go code — no account required.

Generate Go structs with correct JSON/XML tags, pointer types for optional fields, and idiomatic naming.

How to use this converter

1. Paste your YAML into the left editor panel
2. Click Generate
3. Copy the generated Go code from the right panel

No account. No upload. No tracking. Runs entirely in your browser.

Example Go output

type Address struct {
    City string `json:"city"`
    Zip  string `json:"zip"`
}
 
type User struct {
    ID      int      `json:"id"`
    Name    string   `json:"name"`
    Email   *string  `json:"email,omitempty"`
    Address Address  `json:"address"`
}

Why automate YAML-to-Go conversion?

Writing Go struct definitions by hand from YAML is:

• Tedious — especially for deeply nested or large YAML payloads
• Inconsistent — naming conventions drift when done manually across a team
• Fragile — when the YAML schema changes, hand-written models lag behind

Go structs support JSON/XML struct tags (json:"field") that control serialization — this converter generates them automatically.

This converter handles all of that automatically, giving you idiomatic Go code that matches your YAML structure exactly.

Go and YAML: what you need to know

Go is a statically typed, compiled language, widely used in cloud infrastructure, CLIs, and microservices. It uses struct-based with explicit field tags for structured data — making it a natural fit for YAML-driven applications.

What the converter generates

Output follows Go conventions: PascalCase field names, json:"fieldName" struct tags, and pointer types (*string, *int) for nullable fields. Nested objects become separate named structs.

A common gotcha

Go requires exported (capitalized) field names; unexported fields are silently ignored during marshalling.

YAML input characteristics

YAML is a superset of JSON and supports multi-line strings, block scalars, and complex nested structures. YAML is the de-facto standard for cloud-native configuration — Kubernetes, GitHub Actions, and Ansible all use YAML.

When should I use this converter?

Use this when building Go microservices that consume external API responses or config files, and you need correct struct tags without hand-writing each field.

Common use cases

• Generating structs for encoding/json unmarshalling in REST API handlers
• Creating typed models for gRPC service definitions
• Producing structs for Go-based CLI tools that consume config files
• Generating Go models from backend APIs API responses
• Creating typed DTOs for Kubernetes operators
• Rapid prototyping with real YAML payloads
• Keeping Go structs in sync when YAML schemas evolve
• Onboarding new team members by auto-generating the data layer
• Validating YAML contract compatibility with Go type definitions

Frequently asked questions

Does this work for large YAML payloads?

Yes. The converter is optimized for large and deeply nested YAML structures, running entirely in the browser without page reloads or server round-trips.

Does this converter support YAML Ain't Markup Language namespaces and nested structures?

Yes. YAML supports anchors (&) and aliases (*) for reusable values — this converter resolves them before generating types. The parser handles deeply nested structures and generates matching nested Go struct definitions.

How are optional fields handled in the Go output?

Fields that may be absent or null in your YAML are marked as optional in the generated Go code. Note: Go requires exported (capitalized) field names; unexported fields are silently ignored during marshalling.

Can I use the output directly in a backend APIs project?

Yes. The generated Go code follows idiomatic patterns for backend APIs — you can copy it directly into your project.
