Introduction

Bank statements are essential financial documents that contain crucial information about a person or a business’s financial transactions. Extracting data from digital and scanned bank statements can be a time-consuming and error-prone process if done manually. However, with the help of Camelot library in Python for digital and Optical Character Recognition (OCR) technology for scanned, specifically TrOcr in Python, this process can be automated, saving time and reducing errors.

In this blog, we will explore how to use TrOcr, a popular Camelot library and OCR library in Python, to extract data from both digital and scanned bank statements. We will discuss the benefits of using TrOcr for bank statement data extraction and walk through step-by-step instructions on how to implement it in your Python code.

Why Use Camelot for Digital Bank Statement Data Extraction?          

Camelot is a powerful Python library that is specifically designed for extracting tabular data from PDFs, making it ideal for digital bank statement data extraction. Here are some reasons why Camelot is a top choice for this task:

  • Accuracy: Camelot uses advanced algorithms to accurately identify and extract tables from PDFs, even when dealing with complex layouts or multiple tables on a page.
  • Flexibility: Camelot supports different types of PDF layouts, including single-page, multi-page, and scanned PDFs, making it suitable for extracting data from various types of digital bank statements.
  • Customization: Camelot provides options for customizing table extraction settings, such as specifying table regions, column separators, and row separators, to suit your specific bank statement templates.
  • Easy Integration: Camelot offers a simple and intuitive API for integrating table extraction capabilities into your Python code, making it accessible to users with different levels of programming experience.

Step-by-Step Guide to Digital Bank Statement Data Extraction with Camelot in Python

Now let’s dive into the step-by-step guide on how to use Camelot for digital bank statement data extraction in Python. Here’s an overview of the entire process:

Sample digital bank document:

1. Installing and importing the Camelot Library: We will start by installing and importing the Camelot library in Python, along with any other required dependencies.

2. Loading the Digital Bank Statement PDF: We will then load the digital bank statement PDF using Camelot, and pre-process it if necessary.

3. Extracting Tables from the PDF: Next, we will use Camelot to extract tables from the loaded PDF and store the extracted tables in a suitable format for further processing.

4. Data Cleaning and Extraction: We will then clean and pre-process the extracted tables to remove any unwanted characters or noise, and extract the relevant data such as transaction dates, amounts, and descriptions.
