How to extract table from PDF

Extracting tables from PDF files can be a challenging task due to the complex layouts, which can make it difficult for standard text extraction methods to accurately capture tabular data. However, specialized libraries like Aspose.PDF for Python via .NET are specifically designed to address this challenge and offer efficient and reliable table extraction capabilities. By leveraging such libraries, developers can effectively extract tables from PDF files with greater accuracy and ease.

Python Library to extract table from PDF documents

Aspose.PDF for Python comes equipped with a variety of methods and options aimed at ensuring precise and accurate table extraction from PDF files. This powerful library provides techniques such as defining table boundaries, effectively handling headers and footers, and navigating complex layouts. By employing these advanced techniques, data accuracy is greatly enhanced, allowing users to extract tabular data with confidence and reliability. Whether dealing with intricate PDF structures or tables with diverse layouts, Aspose.PDF for Python empowers developers to achieve dependable and accurate table extraction in their Python projects.

The provided Python code illustrates the process of extracting and printing text from a table within a PDF document using the Aspose.PDF library:

• Import the aspose.pdf module to access the functionality of the Aspose.PDF library.
• Load the PDF file named “input.pdf” using the pdf.Document() method and store it in the pdfDocument variable.
• Create a TableAbsorber object named tableAbsorber to extract tables from the PDF document.
• Use the tableAbsorber to visit the first page of the PDF using tableAbsorber.visit(pdfDocument.pages[1]). This step parses all the tables on the first page.
• Obtain a reference to the first table from the list of tables found on the page using absorbedTable = tableAbsorber.table_list[0].
• Iterate through all the rows in the table using a for loop: for pdfTableRow in absorbedTable.row_list.
• Within the row iteration, use another nested for loop to iterate through all the columns in the row: for pdfTableCell in pdfTableRow.cell_list.
• Inside the column iteration, fetch the text fragments of each cell using pdfTableCell.text_fragments, which returns a collection of text fragments.
• Finally, use another for loop to iterate through the text fragments within each cell: for textFragment in textFragmentCollection.
• Within this loop, print the text content of each text fragment using print(textFragment.text).

Use following code snippet for this:

    import aspose.pdf as pdf 
    #Load PDF file 
    pdfDocument = pdf.Document("input.pdf") 
    #Initialize TableAbsorber object 
    tableAbsorber =  pdf.text.TableAbsorber() 
    #Parse all the tables on first page 
    tableAbsorber.visit(pdfDocument.pages[1]) 
    #Get a reference of the first table 
    absorbedTable = tableAbsorber.table_list[0] 
    #Iterate through all the rows in the table 
    for pdfTableRow in absorbedTable.row_list: 
        #Iterate through all the columns in the row 
        for pdfTableCell in pdfTableRow.cell_list: 
            #Fetch the text fragments 
            textFragmentCollection = pdfTableCell.text_fragments 
            #Iterate through the text fragments 
            for textFragment in textFragmentCollection: 
                #Print the text 
                print(textFragment.text)
