Opening a pdf and reading in tables with python pandas

Opening a pdf and reading in tables with python pandas

You can use the tabula-py library in combination with Pandas to extract tables from a PDF file. tabula-py is a Python wrapper for the Tabula Java library, which allows you to extract tables from PDF documents.

Here's how you can open a PDF file and read tables using Python and Pandas:

  • Install the required libraries:

You'll need both Pandas and tabula-py. You can install them using pip:

pip install pandas tabula-py
  • Import the necessary libraries:
import tabula import pandas as pd
  • Specify the path to the PDF file and extract tables:
pdf_path = "path/to/your/pdf/file.pdf" # Extract tables from the PDF tables = tabula.read_pdf(pdf_path, pages='all', multiple_tables=True) # Convert the list of DataFrames into a single DataFrame (if needed) combined_df = pd.concat(tables, ignore_index=True)

In this example:

  • pdf_path should be replaced with the actual path to your PDF file.
  • The tabula.read_pdf() function is used to extract tables from the PDF. The pages parameter specifies the page range to extract tables from (use 'all' for all pages), and multiple_tables=True tells the function to extract multiple tables.
  • The resulting tables variable will be a list of Pandas DataFrames, each representing a table extracted from the PDF.
  • You can now work with the extracted tables as Pandas DataFrames:
for table_df in tables: print(table_df)

Keep in mind that the quality and structure of the extracted tables can vary based on the PDF content and formatting. You might need to fine-tune the extraction process using options provided by tabula-py to get the best results for your specific PDF documents. Refer to the tabula-py documentation for more advanced usage options.
