What is JSON to Go Struct Converter?
JSON to Go Struct Converter is a free online tool that automatically generates Go (Golang) struct definitions from JSON data. It analyzes your JSON structure and creates properly typed Go structs with customizable options including JSON tags, pointer types, and nested struct handling. Perfect for Go developers who need to quickly create data models from API responses or configuration files.
How to Use JSON to Go Converter
Using the converter is simple: paste your JSON data into the input field, customize the conversion settings (struct name, package name, JSON tags, etc.), and the tool automatically generates the corresponding Go struct code. You can configure options like using pointers for optional fields, inlining nested structs, adding omitempty tags, and sorting fields alphabetically. The generated code can be copied to clipboard or downloaded as a .go file.
Key Features
Automatic type inference from JSON values, customizable struct and package names, JSON tag generation with omitempty support, nested struct handling (inline or separate definitions), pointer type support for optional fields, alphabetical field sorting, real-time conversion as you type, and support for complex nested JSON structures. All processing happens in your browser for maximum privacy and speed.
Free Tool Without Registration
This is a completely free tool that requires no registration or sign-up. All JSON to Go struct conversion happens entirely in your browser using JavaScript, so your data never leaves your computer. No data is sent to any server, ensuring complete privacy and security. Perfect for developers working with sensitive data or in environments with strict data policies.

Yes, this JSON to Go converter is completely free to use with no limitations or registration required.
Is my JSON data secure?
Absolutely. All conversion happens entirely in your browser. Your JSON data never leaves your computer and is not sent to any server.
Does it support nested JSON structures?
Yes, the tool fully supports nested objects and arrays. You can choose to inline nested structs or generate separate struct definitions.
Can I customize the generated struct names?
Yes, you can customize both the main struct name and the package name. Nested struct names are automatically generated based on field names.
What about JSON tags and omitempty?
The tool can automatically generate JSON tags for all fields. You can also enable the omitempty option to add omitempty to all JSON tags.
Does it handle different JSON data types correctly?
Yes, the tool infers proper Go types from JSON values: strings become string, integers become int, floats become float64, booleans become bool, and arrays become slices.
