Convert IPYNB (Jupyter Notebook) to TEXT MARKDOWNPHPEXTRA

The IPYNB file extension stands for "Interactive Python Notebook" and is used exclusively with Jupyter Notebook. It is a JSON file format that contains a complete record of user sessions, including code, narrative text, equations, and visualizations. The IPYNB files facilitate reproducible research and easy sharing of data analysis workflows. Originating from the IPython project, Jupyter Notebook has expanded its capabilities to support multiple programming languages, making it a versatile tool in the data science and machine learning communities. The format's history traces back to the early 2010s when it was developed to enhance interactive computing and collaborative work.

The TEXT file extension, associated with PHP Markdown Extra Documentation, refers to plain text files used to write and store documentation. These files are simple, human-readable, and can be easily converted to HTML using Markdown syntax. The TEXT extension is commonly used for README files, configuration files, and other documentation purposes. Markdown Extra enhances the basic Markdown syntax with additional features like tables, footnotes, and definition lists, making it a powerful tool for creating well-structured documentation.
