Camelot: PDF Table Extraction for Humans

tests Documentation Status codecov.io image image image

Camelot is a Python library that can help you extract tables from PDFs.


Extract tables from PDFs in just a few lines of code:

Try it yourself in our interactive quickstart notebook. image

Or check out a simple example using this pdf.

>>> import camelot
>>> tables = camelot.read_pdf('foo.pdf')
>>> tables
<TableList n=1>
>>> tables.export('foo.csv', f='csv', compress=True) # json, excel, html, markdown, sqlite
>>> tables[0]
<Table shape=(7, 7)>
>>> tables[0].parsing_report
{
    'accuracy': 99.02,
    'whitespace': 12.24,
    'order': 1,
    'page': 1
}
>>> tables[0].to_csv('foo.csv') # to_json, to_excel, to_html, to_markdown, to_sqlite
>>> tables[0].df # get a pandas DataFrame!

Camelot also comes packaged with a command-line interface!

Refer to the QuickStart Guide to quickly get started with Camelot, extract tables from PDFs and explore some basic options.

Tip: Visit the parser-comparison-notebook to get an overview of all the packed parsers and their features. image

Note: Camelot only works with text-based PDFs and not scanned documents. (As Tabula explains, "If you can click and drag to select text in your table in a PDF viewer, then your PDF is text-based".)

You can check out some frequently asked questions here.

Why Camelot?

  • Configurability: Camelot gives you control over the table extraction process with tweakable settings.
  • Metrics: You can discard bad tables based on metrics like accuracy and whitespace, without having to manually look at each table.
  • Output: Each table is extracted into a pandas DataFrame, which seamlessly integrates into ETL and data analysis workflows. You can also export tables to multiple formats, which include CSV, JSON, Excel, HTML, Markdown, and Sqlite.
