Go JSON Tutorial: Marshalling and Unmarshalling Explained

What is JSON marshalling and unmarshalling in Go and how does it work? In this video, you’ll learn how to use Go’s encoding/json package to handle JSON data efficiently. We explain how marshalling converts Go data structures like structs, slices, and maps into JSON format using json.Marshal, and how unmarshalling converts JSON data back into Go data structures with json.Unmarshal. You’ll also see how to customize JSON keys using struct tags, handle missing or extra fields, and exclude empty fields using omitempty. By the end of this video, you’ll understand how to manage JSON data in Go with clear examples and practical tips. If you want to improve your Go programming skills and work with APIs or data processing, this guide is for you.
