# Excalibur: A web interface to extract tabular data from PDFs [![Documentation Status](https://readthedocs.org/projects/excalibur-py/badge/?version=master)](https://excalibur-py.readthedocs.io/en/master/) [![image](https://img.shields.io/pypi/v/excalibur-py.svg)](https://pypi.org/project/excalibur-py/) [![image](https://img.shields.io/pypi/l/excalibur-py.svg)](https://pypi.org/project/excalibur-py/) [![image](https://img.shields.io/pypi/pyversions/excalibur-py.svg)](https://pypi.org/project/excalibur-py/) [![Gitter chat](https://badges.gitter.im/camelot-dev/Lobby.png)](https://gitter.im/camelot-dev/Lobby) **Excalibur** is a web interface to extract tabular data from PDFs, written in **Python 3**! It is powered by [Camelot](https://camelot-py.readthedocs.io/). **Note:** Excalibur only works with text-based PDFs and not scanned documents. (As Tabula [explains](https://github.com/tabulapdf/tabula#why-tabula), "If you can click and drag to select text in your table in a PDF viewer, then your PDF is text-based".) ## Using Excalibur **Note:** You need to [install ghostscript](https://camelot-py.readthedocs.io/en/master/user/install-deps.html) before moving forward. After [installing Excalibur with pip](https://excalibur-py.readthedocs.io/en/master/user/install.html), you need to initialize the metadata database using:
$ excalibur initdb
And then start the webserver using:
$ excalibur webserver
That's it! Now you can go to http://localhost:5000 and start extracting tabular data from your PDFs. 1. **Upload** a PDF and enter the page numbers you want to extract tables from. 2. Go to each page and select the table by drawing a box around it. (You can choose to skip this step since Excalibur can automatically detect tables on its own. Click on "**Autodetect tables**" to see what Excalibur sees.) 3. Choose a flavor (Lattice or Stream) from "**Advanced**". a. **Lattice**: For tables formed with lines. b. **Stream**: For tables formed with whitespaces. 4. Click on "**View and download data**" to see the extracted tables. 5. Select your favorite format (CSV/Excel/JSON/HTML) and click on "**Download**"! **Note:** You can also download executables for Windows and Linux from the [releases page](https://github.com/camelot-dev/excalibur/releases) and run them directly! ![usage.gif](https://excalibur-py.readthedocs.io/en/master/_images/usage.gif) ## Why Excalibur? - Extracting tables from PDFs is hard. A simple copy-and-paste from a PDF into an Excel doesn't preserve table structure. **Excalibur makes PDF table extraction very easy**, by automatically detecting tables in PDFs and letting you save them into CSVs and Excel files. - Excalibur uses [Camelot](https://camelot-py.readthedocs.io/) under the hood, which gives you additional settings to tweak table extraction and get the best results. You can see how it performs better than other open-source tools and libraries [in this comparison](https://github.com/socialcopsdev/camelot/wiki/Comparison-with-other-PDF-Table-Extraction-libraries-and-tools). - You can save table extraction [settings](https://excalibur-py.readthedocs.io/en/master/user/faq.html#faq) (like table areas) for a PDF once, and apply them on new PDFs to extract tables with similar structures. - You get complete control over your data. All file storage and processing happens on your own local or remote machine. - Excalibur can be configured with MySQL and Celery for parallel and distributed workloads. By default, sqlite and multiprocessing are used for sequential workloads. ## Installation ### Using pip After installing [ghostscript](https://www.ghostscript.com/), which is one of the requirements for Camelot (See [install instructions](https://camelot-py.readthedocs.io/en/master/user/install-deps.html)), you can simply use pip to install Excalibur:
$ pip install excalibur-py
### From the source code After installing ghostscript, clone the repo using:
$ git clone https://www.github.com/camelot-dev/excalibur
and install Excalibur using pip:
$ cd excalibur
$ pip install .
