Introduction

In this video, we will be exploring how Chat GPT can assist us in writing Python code to download and extract text from a PDF file. We will compare our own code with the code generated by Chat GPT to see if it offers any improvements. We will also discuss the potential applications of this AI Chat bot in the field of accounting.

Pros:

  • Chat GPT provides an alternative approach to writing Python code for extracting data from PDF files.
  • The generated code is parameterized and can be easily reused in multiple instances.
  • It saves time by automating the process of downloading and extracting text from a PDF file.

Cons:

  • The generated code may sometimes violate content policies, raising concerns about compliance.
  • Reliability and accuracy of the generated code need to be evaluated against user requirements.

Downloading and Extracting Text from a PDF file

To begin, we will ask Chat GPT to help us download a specific PDF file and extract its text. We will provide the file path and the page number as parameters. A python code will be generated to accomplish this task.

PiPDF2 and Requests libraries

Chat GPT suggests using the "PiPDF2" library to handle PDF files and the "Requests" library for downloading content from the web. This combination offers a robust solution for our task.

Parameters:

  • URL: The URL of the PDF file.
  • Page number: The desired page number to extract text from.

Refactoring the Code into a Function

To make the code more organized and reusable, we can refactor it into a function. This will allow us to specify the URL and page number as parameters. The refactored code will be cleaner and easier to Read.

Function Parameters:

  • URL: The URL of the PDF file.
  • Page number: The desired page number to extract text from.

Testing the Refactored Code

Now, we will test the refactored code. We will assign the URL and page number values and run the code to download and extract the text from the specified page of the PDF file.

Code Execution

We input the PDF file location and page number 16. The code executes successfully, and We Are able to download the file and extract the desired text. This demonstrates the effectiveness of using Chat GPT to generate code that automates this process.

Conclusion

Using Chat GPT to generate Python code for downloading and extracting text from a PDF file has proved to be a successful venture. The code is concise, reusable, and performs the desired task accurately. However, caution must be exercised to ensure compliance with content policies and to evaluate the reliability of the generated code.

Next Steps

In the next video, we will explore how Chat GPT can assist us in writing regular expressions to extract Meaningful data from the extracted text. This data will be organized into a data frame, further enhancing the efficiency of our accounting processes.

Highlights

  • Chat GPT provides an efficient solution for automating the extraction of text from PDF files.
  • Refactoring the code into a function enhances code readability and reusability.
  • The generated code successfully downloads and extracts text from the specified PDF file.
  • Compliance with content policies and code reliability need to be considered.

FAQ

Q: Can Chat GPT generate code for multiple pages of a PDF file? A: Yes, by using the function parameter for the page number, you can easily extract text from any desired page of a PDF file.

Q: Are there any limitations to using Chat GPT for this task? A: Chat GPT may sometimes generate code that violates content policies, and hence, caution needs to be exercised. Additionally, the generated code needs to be evaluated for reliability and accuracy against user requirements.

Q: How long does it take to download and extract text from a PDF file using Chat GPT? A: Chat GPT enables you to accomplish this task in a matter of minutes, saving valuable time and effort.

Q: Can the generated code be modified or customized as per our requirements? A: Absolutely! The generated code can be easily modified or customized to suit specific needs or preferences.
