Why does the generator use pointer types for nullable fields?

In Go, primitive types like string, int, and bool have default zero values ('', 0, false). If a JSON field contains null, deserializing into a primitive would erase the distinction between zero and null. Using a pointer (e.g. *string or *int64) allows Go to accurately represent null as nil.

How does the generator handle Go reserved keywords?

Since Go requires struct fields to be capitalized to be exported and visible to encoding/json, names like Type, Range, or Case automatically become capitalized PascalCase, which completely avoids keyword collisions while keeping the original key in the `json:...` tag.

What is the JSON to Go Struct Converter?

The PriyGop JSON to Go Struct Converter transforms complex JSON payloads into clean, idiomatic Golang struct definitions. It automatically creates `json:"..."`tags, formats fields according to standard gofmt alignment conventions, and distinguishes between zero values and null values using pointer types.

Golang Struct Generation Rules

Exported PascalCase Fields: Field names are capitalized to make them exported and accessible to the encoding/json serializer.
Standard Acronym Capitalization: Acronyms such as ID, URL, and HTTP are preserved in uppercase (e.g. UserID).
Pointer Types: Nullable JSON values are represented as pointers (e.g. *string, *int64) to differentiate null from zero values.
Omitempty Flag: Optional properties can include ,omitempty in their struct tag.
