Convert HWPX (Hanword) to JSON NATIVEAST

HWPX (Hangul Word Processor XML) is an advanced document format used by Hanword, developed by Hancom. It serves as an XML-based alternative to the proprietary HWP format, enhancing interoperability and accessibility. Introduced to improve document structure and compatibility, HWPX enables easier data exchange, integration with various applications, and better support for modern document processing workflows. It is widely used in South Korea for official documents, offering structured content representation while maintaining the rich formatting capabilities of Hanword.

The JSON file extension is used for encoding the Abstract Syntax Tree (AST) of programming languages in a lightweight, text-based format. It enables efficient data interchange and enhances performance by providing a structured representation of code components. Since its standardization in the early 2000s, JSON has become indispensable in modern web development and software engineering for its simplicity, readability, and compatibility across various programming environments.
