Table Extraction

  

This is a Proof of Concept (PoC) for extracting tables from text-based PDF documents using the GMFT library and serving results via a Gradio app.

What this Space does

• —Upload a text-based PDF.
• —Automatically detects tables and extracts them into structured JSON.
• —Each extracted table includes:
• —Page number + Table ID
• —Table columns and data
• —Bounding box + captions (if detected)
• —Outputs are saved as:
• —tables.json → structured table data
• —metrics.json → per-file stats (tables found, processing time, etc.)
• —Tables are rendered back in the UI for quick inspection.
• —JSON + metrics are available for download.

⚠️ Limitations

• —This PoC currently works best with text-based PDFs.
• —Scanned PDFs may not be parsed correctly (OCR support is not yet included).
