Java로 PDF에서 데이터를 추출하는 방법

5.1. Extract Data from PDF documents

Using IronPDF for Java, you can easily extract text data from PDF documents. Below is the example code for extracting data from a PDF file.

PDF Input

// Import the necessary IronPDF package for working with PDF documents
import com.ironsoftware.ironpdf.PdfDocument;

import java.io.IOException;
import java.nio.file.Paths;

public class Main {
    public static void main(String[] args) throws IOException {
        // Load the PDF document from the specified file
        PdfDocument pdf = PdfDocument.fromFile(Paths.get("business plan.pdf"));

        // Extract all text from the PDF document
        String text = pdf.extractAllText();

        // Print the extracted text to the console
        System.out.println("Text extracted from the PDF: " + text);
    }
}

// Import the necessary IronPDF package for working with PDF documents
import com.ironsoftware.ironpdf.PdfDocument;

import java.io.IOException;
import java.nio.file.Paths;

public class Main {
    public static void main(String[] args) throws IOException {
        // Load the PDF document from the specified file
        PdfDocument pdf = PdfDocument.fromFile(Paths.get("business plan.pdf"));

        // Extract all text from the PDF document
        String text = pdf.extractAllText();

        // Print the extracted text to the console
        System.out.println("Text extracted from the PDF: " + text);
