![]() Ex – ash, 23, 2, 3.Īnnotations: an annotation associates an object as a note, an image or bounding box with a location on a page of a PDF document, or provides a way to interact with the user using the mouse and keyboard. But nevertheless, none of them worked except PyMuPDF.īefore entering the code, it is important to understand the meaning of 2 important terms that would help you understand the code. I have tried many python libraries like PyPDF2, PDFMiner, luciopdf, Camelot y tabulated. Here is the PDF and the red bounding boxes we need to extract data from. Now, I will show you how I extracted data from bounding boxes in a PDF with multiple pages. This library provided many applications, how to extract images from PDF, extract texts in different ways, make annotations, draw a bounding box around the texts along with library features like PyPDF2. I have used the PyMuPDF library for this purpose. Here, I will show you a more successful technique and Python library through which you can extract data from bounding boxes in unstructured PDF files and then perform the data cleaning operation on the extracted data and convert it to a structured format. To analyze unstructured data, we need to convert them to a structured form.Īs such, there is no specific technique or procedure to extract data from unstructured PDF files, as the data is stored randomly and it depends on the type of data you want to extract from the PDF. ![]() In this case, it is not feasible to use the above python libraries, since they will give ambiguous results. In all these cases, data is in structured form, namely, sequential, forms or tables.īut nevertheless, In the real world, most of the data is not present in any of the forms and there is no data order. You can also extract tables to PDF through the Camelot Library. For instance, you can use the PyPDF2library to extract text from PDF files where the text is sequential or formatted, namely, in lines or shapes. There are a couple of Python libraries with which you can extract data from PDF files. Although in some files, data can be easily extracted as in CSV, while in files like unstructured PDF we have to perform additional tasks to extract data. ![]() This article was published as part of the Data Science Blogathon Introduction:ĭata extraction is the process of extracting data from various sources such as CSV files, web, PDF, etc.
