Convert JSON NATIVEAST to PNM

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.

The PNM (Portable Anymap) file extension, developed by Jef Poskanzer in the 1980s, stands for Portable Any Map. It is an uncompressed raster graphics format designed for portable image storage and exchange, encompassing three sub-formats: PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files store image data in plain text or binary format, ensuring easy usage across different platforms and applications. This format is widely supported by various image editing software and is valued for its simplicity and lossless compression.
