Introduction

PDFs are popular for their stability, security, and ease of access. However, extracting data from PDFs can be a daunting task. Manually entering data from PDFs is not only a cumbersome task but is also highly inefficient. Fortunately, there are several ways to extract tables from PDFs using python.

Approaches to Extract Tables using Python

In this article, we explore two common methods that are used to extract tables from PDFs – by using the package ‘tabula’ and the package ‘camelot’.

Tabula Processing Method

The Tabula method has been around for longer and it is still widely used for straightforward tables. Tabula package extracts tables as they appear on PDF pages. This package works well if the table is structured cleanly and consistently with a defined space between each cell. Its major drawback is that it isn’t able to handle more complexly formatted tables, tables with rowspans or colspans in form, or when merged cells occur.

Camelot Processing Method

The Camelot method, on the other hand, is a relatively new Python package. This package is more advanced than the Tabula one for processing complex or multi-page tables. Camelot uses an image-processing technique to locate and split tables into separate rectangular cells, then extracts the text from within each cell. Camelot package works well even in cases where tables have multiple headers and columns of varying widths.

Features Tabula and Camelot

Features	Tabula	Camelot
Stability	Less stable than Camelot	Highly stable
Ease of use	Easy to use with a relatively shorter learning curve	Easy to use with detailed documentation
Table extraction Time	Slower extraction times for large tables	Can be faster but slower when dealing with complex tables
Accuracy	Produces accurate results for straightforward tables	Produces accurate results even in cases of complex tables
Suitability	Ideal for simple tables where cells have a clear structure and defined space between them	Suitable for complex tables, tables with multiple columns, text wrapping, and row/col merging

Conclusion

Both Tabula and Camelot are effective methods for extracting tables from PDFs using python. However, which one of the two packages to choose would depend upon the type of table you need to extract, the accuracy required, and the speed at which you need the task to be done.

You should also take into consideration your proficiency with each package – Tabula being easier to use and hence, suitable for beginners while Camelot is more tailored for experienced users.

In conclusion, it is important to weigh the pros and cons of both methods to determine which one best suits your needs. By making an informed choice on the basis of the factors mentioned above, you can avoid headaches of attempting to edit or copy complex tables manually, and achieve the correct job in just a few Python codes.

   import re

   from PyPDF2 import PdfFileReader

   pdf = PdfFileReader(open('file.pdf', 'rb'))

   table_regex = re.compile(r'your_table_regex_here')

   for page in range(pdf.getNumPages()):

   text = pdf.getPage(page).extractText()

   match = table_regex.search(text)

   if match:

   table_text = match.group(0)

   # convert table_text into a Pandas DataFrame
