Camelot: PDF Table Extraction for Humans
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.
Or check out a simple example using this pdf.
<pre> >>> 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! </pre>| Cycle Name | KI (1/km) | Distance (mi) | Percent Fuel Savings | | | | | ---------- | --------- | ------------- | -------------------- | --------------- | --------------- | -------------- | | | | | Improved Speed | Decreased Accel | Eliminate Stops | Decreased Idle | | 2012_2 | 3.30 | 1.3 | 5.9% | 9.5% | 29.2% | 17.4% | | 2145_1 | 0.68 | 11.2 | 2.4% | 0.1% | 9.5% | 2.7% | | 4234_1 | 0.59 | 58.7 | 8.5% | 1.3% | 8.5% | 3.3% | | 2032_2 | 0.17 | 57.8 | 21.7% | 0.3% | 2.7% | 1.2% | | 4171_1 | 0.07 | 173.9 | 58.1% | 1.6% | 2.1% | 0.5% |
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.
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 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.
