         "This Python script extracts text and tables from a PDF file, converts the tables into a human-readable text format using Azure OpenAI, and writes the processed content to a text file. The script uses pdfplumber to extract text and table data from each page of the PDF. For tables, it sends a cleaned version (handling any missing or None values) to Azure OpenAI, which generates a natural language summary of the table. The extracted non-table text and the summarized table text are then saved to a text file for easy search and readability."
