JSON to Go

This lesson is part of Web Developer Tools · All levels

Summary

The JSON to Go converter produces a struct declaration with a field representing each JSON key. The field must be prefixed with capital letters in order to be accessible from another package, whereas the json tag specifies the key name when serialized. The data type is mapped to string, int, float64, bool, slice, or cluster struct. The result can be used directly with json encoding to read and write JSON.
