Convert YAML to Go online, free. YAML is an indentation-based superset of JSON favoured for human-edited config. Go structs with field tags marshal cleanly to and from data formats. YAML to Go conversion parses your YAML against the YAML 1.2.2 grammar (https://yaml.org/spec/1.2.2/), builds an in-memory model of its keys, nested objects and arrays, then emits ready-to-use Go types as structs with json field tags following the The Go Programming Language Spec conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include Go microservices, CLIs and encoding/json struct mapping.
It maps the full structure of your YAML onto idiomatic Go types, following the The Go Programming Language Spec conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste YAML and generate Go types from Go immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested YAML objects, tables and arrays are mapped faithfully onto Go, including nested types and optional fields.
Your YAML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A YAML document and its Go equivalent:
YAML input:
label: web
replicas: 3
exposed: falseOutput:
type Service struct {
Label string `yaml:"label"`
Replicas int `yaml:"replicas"`
Exposed bool `yaml:"exposed"`
}Paste your YAML into the editor and press "Convert to Go". The tool parses it against the YAML 1.2.2 grammar, then generates Go types following The Go Programming Language Spec conventions — instantly and entirely in your browser. You can validate or format the YAML first to be sure it is clean.
YAML anchors and aliases are expanded and comments are dropped before Go is produced, and indentation defines the structure. Note that YAML 1.1 treats words like "yes" and "no" as booleans, so quote them if you want strings.
Optional or nullable members in the generated Go are inferred from keys missing in some records of your YAML, following The Go Programming Language Spec. Include the optional fields in your sample so they are typed correctly.
YAML (YAML Ain't Markup Language) (YAML) — YAML is an indentation-based superset of JSON favoured for human-edited config. Go (Golang) structs (Go) — Go structs with field tags marshal cleanly to and from data formats. This converter maps the structure of your YAML onto Go so you can use it for Go microservices.
Yes. Invalid YAML is flagged with a clear error before anything is converted. Common YAML problems to check are spaces (never tabs) for indentation, consistent indent levels, and no duplicate keys. Starting from clean input keeps the generated Go accurate.
Yes. The entire YAML-to-Go conversion runs locally in your browser in JavaScript — your YAML is never uploaded, logged or stored. That matters when the data is something like Kubernetes & Docker Compose manifests, which should not leave your machine.
The generated Go is ready for Go microservices, CLIs and encoding/json struct mapping. Copy or download it and drop it straight into your codebase.
