🚀 E2M: Everything to Markdown

Everything to Markdown

E2M is a Python library that can parse and convert various file types into Markdown format. By utilizing a parser-converter architecture, it supports the conversion of multiple file formats, including doc, docx, epub, html, htm, url, pdf, ppt, pptx, mp3, and m4a.

✨The ultimate goal of the E2M project is to provide high-quality data for Retrieval-Augmented Generation (RAG) and model training or fine-tuning.

Core Architecture of the Project:

• Parser: Responsible for parsing various file types into text or image data.
• Converter: Responsible for converting text or image data into Markdown format.

Generally, for any type of file, the parser is run first to extract internal data such as text and images. Then, the converter is used to transform this data into Markdown format.

🆙 Next Level

🛠️ E2MParser

E2MParser is an integrated parser that supports multiple file types. It can be used to parse a wide range of file types into Markdown format.

from wisup_e2m import E2MParser

# Initialize the parser with your configuration file
ep = E2MParser.from_config("config.yaml")

# Parse the desired file
data = ep.parse(file_name="/path/to/file.pdf")

# Print the parsed data as a dictionary
print(data.to_dict())

🛠️ E2MConverter

E2MConverter is an integrated converter that supports text and image conversion. It can be used to convert text and images into Markdown format.

from wisup_e2m import E2MConverter

ec = E2MConverter.from_config("./config.yaml")

text = "Parsed text data from any parser"

ec.convert(text=text)

images = ["test.jpg", "test.png"]
ec.convert(images=images)

You can use a config.yaml file to specify the parsers and converters you want to use. Here is an example of a config.yaml file:

parsers:
    doc_parser:
        engine: "pandoc"
        langs: ["en", "zh"]
    docx_parser:
        engine: "pandoc"
        langs: ["en", "zh"]
    epub_parser:
        engine: "unstructured"
        langs: ["en", "zh"]
    html_parser:
        engine: "unstructured"
        langs: ["en", "zh"]
    url_parser:
        engine: "jina"
        langs: ["en", "zh"]
    pdf_parser:
        engine: "marker"
        langs: ["en", "zh"]
    pptx_parser:
        engine: "unstructured"
        langs: ["en", "zh"]
    voice_parser:
        # option 1: use openai whisper api
        # engine: "openai_whisper_api"
        # api_base: "https://api.openai.com/v1"
        # api_key: "your_api_key"
        # model: "whisper"

        # option 2: use local whisper model
        engine: "openai_whisper_local"
        model: "large" # available models: https://github.com/openai/whisper#available-models-and-languages
