In this tutorial, we'll show you how to use IronPDF for Java to extract data from a PDF file. Setting up the environment, importing the library, reading the input file, and extracting the needed data are all steps we'll do. You will understand precisely how to extract data from a PDF file using IronPDF for Java at the conclusion of this article.
IronPDF is a software library that provides developers with the ability to generate, edit, and extract data from PDF files within their Java applications. It allows you to create PDFs from HTML, ASPX, images, and more, as well as merge, split, and manipulate existing PDFs. IronPDF also provides the ability to secure PDFs with password protection and add digital signatures, among other features.
IronPDF for Java is developed and maintained by Iron Software. One of its top-rated features is to extract text and data from PDF files as well as from HTML and URLs.
To use IronPDF to extract data from PDF files, you must meet the following prerequisites:
Installing IronPDF for Java is easy and uncomplicated, provided all the requirements are met. This guide will use JetBrains' IntelliJ IDEA to demonstrate the installation and run sample code.
Here's what to do:
Open IntelliJ IDEA: Launch JetBrains IntelliJ IDEA on your system.
Create a Maven Project: In IntelliJ IDEA, create a new Maven project. This will provide a suitable environment for the installation of IronPDF for Java.
A new window will appear. Enter the name of the project and click on Finish.
A new project with a pom.xml will open once you click Finish. This will be used to add IronPDF Java Maven dependencies.
Add the following dependencies in the pom.xml file or you can download the JAR file from the following link.
<dependency>
<groupId>com.ironsoftware</groupId>
<artifactId>com.ironsoftware</artifactId>
<version>2024.3.1</version>
</dependency>
Once you placed the dependencies in the pom.xml file, a small icon will appear in the right top corner of the file.
Install IronPDF for Java's Maven dependencies by clicking this button. Depending on the speed of your internet connection, this should just take a few minutes.
IronPDF is a .NET library for creating, editing and extracting data from PDF documents. It allows developers to extract text, images, and other data from PDFs using C# or VB.NET code. With IronPDF, you can also manipulate PDFs, such as converting HTML to PDF or adding watermarks or annotations to existing PDFs.
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.
import com.ironsoftware.ironpdf.License;
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 {
PdfDocument pdf = PdfDocument.fromFile(Paths.get("bussiness plan.pdf"));
String text = pdf.extractAllText();
System.out.println("Text extracted from the PDF: " + text);
}
}
The source code produces the output given below:
> Text extracted from the PDF:
>
> CRAFT-ARENA
>
> Muhammad Waleed Butt
>
> Hassan Khan
>
> ABOUT US
>
> Craft-Arena is a partnershipbased business that will help local crafters of Pakistan to sell their handy crafts at good prices and helps them earn good living.
IronPDF for Java converts the URL to PDF in runtime and extracts text from it. In this example, we will see the source code to extract text from URLs.
import com.ironsoftware.ironpdf.License;
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 {
PdfDocument pdf = PdfDocument.renderUrlAsPdf("https://ironpdf.com/java/");
// new PDFparser
String text = pdf.extractAllText();
System.out.println("Text extracted from the URLs: " + text);
}
}
To extract table data from a PDF using IronPDF for Java is very simple; all you need is a PDF containing a table, and to run the below code.
import com.ironsoftware.ironpdf.License;
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 {
PdfDocument pdf = PdfDocument.fromFile(Paths.get("table.pdf"));
String text = pdf.extractAllText();
System.out.print("Text extracted from the Marked tables: " + text);
}
}
