Camelot: PDF Table Extraction for Humans

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

Note: You can also check out Excalibur, the web interface to Camelot!

Here's how you can extract tables from PDFs. You can check out the PDF used in this example here.

>>> import camelot
>>> tables = camelot.read_pdf('foo.pdf')
>>> tables
<TableList n=1>
>>> tables.export('foo.csv', f='csv', compress=True) # json, excel, html, 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_sqlite
>>> tables[0].df # get a pandas DataFrame!

4171_1	0.07	173.9	58.1%	1.6%	2.1%	0.5%

Camelot also comes packaged with a command-line interface!

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".)

Why Camelot?

Configurability: Camelot gives you control over the table extraction process with its tweakable settings.
Metrics: Bad tables can be discarded 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 and Sqlite.
