Document to Text Reborn (Digital Archaeologist)

Overview

This skill utilizes a 3-layer extraction model to "excavate" meaning and aesthetics from various document formats. It separates pure content from design and metadata, enabling high-fidelity analysis and reuse.

3-Layer Extraction Model

• Content Layer (Soul): High-fidelity text extraction maintaining structural elements like headings and tables (Markdown output).

• Aesthetic Layer (Mask): Extraction of design parameters, colors, fonts, and layout grid information.

• Metadata Layer (Context): File properties, authorship, and contextual markers.

Supported Formats

• PDF: Text and metadata. (Aesthetic: Coordinate-based analysis)

• Word (.docx ): Structural Markdown conversion. (Aesthetic: Style extraction)

• Excel (.xlsx ): Multi-sheet CSV extraction.

• PowerPoint (.pptx ): Slide-based content extraction.

• Images: OCR supporting English and Japanese.

Usage

node dist/index.js <file_path> [options]

Options

• --mode, -m : Extraction mode. Choices: content , aesthetic , metadata , all (default).

• --out, -o : Save the structural JSON result to a file.
