            String outputText = Jsoup.clean(htmlString, new Whitelist());

            System.out.println(outputText);

import org.jsoup.Jsoup;
import org.jsoup.safety.Whitelist;

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

public class ConvertHtmlToTextFromFile1 {
    public static void main(String... args) {
        try {
            String fileName = "sample.html";
            Path filePath = Paths.get(fileName);
            byte[] fileBytes = Files.readAllBytes(filePath);
            String htmlString = new String(fileBytes, "UTF-8");
            String outputText = Jsoup.clean(htmlString, new Whitelist());

            System.out.println(outputText);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

The output is:

Example 2 read HTML file using Jsoup.parse() method.

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.safety.Whitelist;

import java.io.File;

public class ConvertHtmlToTextFromFile2 {
    public static void main(String... args) {
        try {
            String fileName = "sample.html";
            File file = new File(fileName);

            String htmlString = document.html();
            String outputText = Jsoup.clean(htmlString, new Whitelist());

            System.out.println(outputText);
