Convert common book file types to text for machine learning

Convert Ebook File

Overview

This Python script provides functionality for converting various ebook file formats (EPUB, DOCX, PDF, TXT) into a standardized text format. The script processes each file, identifying chapters, and replaces chapter headers with asterisks. It also performs OCR (Optical Character Recognition) for image-based text using GPT-4o and standardizes the text by desmartening punctuation.

Features

• File Format Support: Handles EPUB, DOCX, PDF, and TXT formats.
• Chapter Identification: Detects and marks chapter breaks.
• OCR Capability: Converts text from images using OCR.
• Text Standardization: Replaces smart punctuation with ASCII equivalents.

Requirements

To run this script, you need Python 3.9 or above and the following packages:

• python-docx
• openai
• python-dotenv
• bs4
• pdfminer.six
• pillow

Usage

1. Ensure all dependencies are installed.
2. Set your environment variable for the OpenAI API key.
3. Place your ebook files in a known directory.
4. Run the script with the path to the ebook file and a metadata dictionary with keys of 'title' and 'author' as arguments.

Functions

• convert_file(file_path: str, metadata: dict) -> str: Main function to convert an ebook file to text.
