What is JSON minification?

JSON minification is the process of removing unnecessary whitespace, line breaks, and formatting from JSON data to reduce its file size. This compression technique preserves the data structure and values while eliminating all human-readable formatting, making the JSON compact and optimized for transmission and storage.
