## What it is
Excalibur is a self-hosted web interface for extracting tabular data from text-based PDFs, built on top of the Camelot PDF table extraction library. Users upload PDFs, select or auto-detect tables by drawing boxes, and download results as CSV, Excel, JSON, or HTML.

## Use cases
- extract tables from pdf files
- convert pdf tables to csv or excel
- scrape tabular data from text-based pdfs
- select table regions in a pdf and export data
- alternative to tabula for pdf table extraction
- batch download tables from pdf reports

## When to choose
- you want a point-and-click GUI instead of writing Python code with Camelot
- your PDFs are text-based (you can select text in a viewer)
- you need exports in CSV, Excel, JSON, or HTML formats
- you want a free, self-hosted Tabula alternative

## When to avoid
- your PDFs are scanned images rather than text-based
- you need fully automated, headless bulk extraction without a UI (use Camelot directly)
- you need OCR for image-only documents

## Facets
- artifact type: application
- maturity: active
- function: pdf, ocr, data-science, gui
- domain: pdf, files, data-science, developer-tools
- platform: python, cross-platform, self-hosted
