Plain text (.txt) files are simple and widely used, but they lack formatting and structure. If you need to enhance a TXT file with headings, fonts, tables, or images, converting it to a Word (.docx) file is a great solution.

In this tutorial, you'll learn how to convert a .txt file to a .docx Word document in Java using Spire.Doc for Java — a powerful library for Word document processing.

Why choose Spire.Doc for Java:

• The converted Word document preserves the line breaks and content from the TXT file.
• You can further modify fonts, add styles, or insert images using Spire.Doc's rich formatting APIs.
• Supported various output formats, including converting Word to PDF, Excel, TIFF, PostScript, etc.

Prerequisites

To convert TXT to Word with Spire.Doc for Java smoothly, you should download it from its official download page and add the Spire.Doc.jar file as a dependency in your Java program.

If you are using Maven, you can easily import the JAR file by adding the following code to your project's pom.xml file:

Steps to Convert TXT to Word in Java

Now let's take a look at how to implement it in code. With Spire.Doc for Java, the process is straightforward. You can complete the conversion with just a few lines — no need for manual formatting or additional dependencies.

To help you better understand the code:

• Document is the core class that acts as an in-memory representation of a Word document.
• loadFromFile() uses internal parsers to read .txt content and wrap it into a single Word section with default font and margins.
• When saveToFile() is called, Spire.Doc automatically converts the plain text into a .docx file by generating a structured Word document in the OpenXML format.

Below is a step-by-step code example to help you get started quickly:

import com.spire.doc.Document;
import com.spire.doc.FileFormat;

public class ConvertTextToWord {

    public static void main(String[] args) {

        // Create a Text object
        Document txt = new Document();

        // Load a Word document
        txt.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.txt");

        // Save the document to Word
        txt.saveToFile("ToWord.docx", FileFormat.Docx);

        // Dispose resources
        doc.dispose();
    }
}

Tip:

After converting TXT files to DOC/DOCX, you can further customize the document's formatting as needed. To simplify this process, Spire.Doc for Java provides built-in support for editing text properties such as changing font color, inserting footnote, adding text and image watermark, etc.

How to Convert Word to TXT with Java

Except for TXT to Word conversion, Spire.Doc for Java also supports converting DOC/DOCX files to TXT format, making it easy to extract plain text from richly formatted Word documents. This functionality is especially useful when you need to strip out styling and layout to work with clean, raw content — such as for text analysis, search indexing, archiving, or importing into other systems that only support plain text.

Simply copy the code below and run the code to manage conversion:

import com.spire.doc.Document;
import com.spire.doc.FileFormat;

public class ConvertWordtoText {

    public static void main(String[] args) {

        // Create a Doc object
        Document doc = new Document();

        // Load a Word document
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.doc");

        // Save the document to Word
        doc.saveToFile("ToText.txt", FileFormat.Txt);

        // Dispose resources

Batch Conversion of Multiple HTML Files to Word in Java

Sometimes you may need to convert hundreds of HTML files into Word documents. Here’s how to batch process them in Java.

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.documents.XHTMLValidationType;
import java.io.File;

public class BatchConvertHtmlToWord {
    public static void main(String[] args) {
        File folder = new File("C:\\Users\\Administrator\\Desktop\\HtmlFiles");

        for (File file : folder.listFiles()) {
            if (file.getName().endsWith(".html") || file.getName().endsWith(".htm")) {
                Document document = new Document();
                document.loadFromFile(file.getAbsolutePath(), FileFormat.Html, XHTMLValidationType.None);

                String outputPath = "output/" + file.getName().replace(".html", ".docx");
                document.saveToFile(outputPath, FileFormat.Docx);
                document.dispose();

                System.out.println(file.getName() + " converted to Word!");
            }
        }
    }
}

This approach is great for reporting systems where multiple HTML reports are generated daily.

Best Practices for HTML to Word Conversion

• Use Inline CSS for Reliable Styling
  Inline CSS ensures that fonts, colors, and spacing are preserved during conversion. External stylesheets may not always render correctly, especially if they are not accessible at runtime.
• Validate HTML Structure
  Well-formed HTML with proper nesting and closed tags helps render tables, lists, and headings accurately.
• Optimize Images
  Use absolute URLs or embed images as base64. Resize large images to fit Word layouts and reduce file size.
• Manage Resources in Batch Conversion
  When processing multiple files, convert them one by one and call dispose() after each document to prevent memory issues.
• Preserve Page Layouts
  Set page margins, orientation, and paper size to ensure the Word document looks professional, especially for reports and formal documents.

Extract Text from URL

To extract text from a URL, users need to create a custom method to retrieve the HTML file from the URL and then extract the text from it. The detailed steps are as follows:

• Create an object of Document class.
• Use the custom method readHTML() to get the HTML file from a URL and return the file path.
• Load the HTML file using Document.loadFromFile(filename, FileFormat.Html) method.
• Get the text from the HTML file using Document.getText() method.
• Write the text to a TXT file.

import com.spire.doc.Document;
import com.spire.doc.FileFormat;

import java.io.*;
import java.net.URL;
import java.net.URLConnection;

public class ExtractTextFromURL {
    public static void main(String[] args) throws IOException {
        //Create an object of Document
        Document doc = new Document();

        //Call the custom method to load the HTML file from a URL
        doc.loadFromFile(readHTML("https://aeon.co/essays/how-to-face-the-climate-crisis-with-spinoza-and-self-knowledge", "output.html"), FileFormat.Html);

        //Get the text from the HTML file
        String urlText = doc.getText();

        //Write the text to a TXT file
        FileWriter fileWriter = new FileWriter("URLText.txt");
        fileWriter.write(urlText);
    }

    public static String readHTML(String urlString, String saveHtmlFilePath) throws IOException {

        //Create an object of URL class
        URL url = new URL(urlString);

        //Open the URL
        URLConnection connection = url.openConnection();

        //Save the url as an HTML file
        BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(saveHtmlFilePath), "UTF-8"));
        String line;
        while ((line = reader.readLine()) != null) {
            writer.write(line);
            writer.newLine();
        }

        reader.close();
        writer.close();

        //Return the file path of the saved HTML file
        return saveHtmlFilePath;
    }

Word and Excel are different from each other in terms of their uses and functioning. Word is used primarily for text documents such as essays, emails, letters, books, resumes, or academic papers where text formatting is essential. Excel is used to save data, make tables and charts and make complex calculations.

It is not recommended to convert a complex Word file to an Excel spreadsheet, because Excel can hardly render contents in the same way as Word. However, if your Word document is mainly composed of tables and you want to analyze the table data in Excel, you can use Spire.Office for Java to convert Word to Excel while maintaining good readability.

Install Spire.Office for Java

First of all, you're required to add the Spire.Office.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Convert Word to Excel in Java

This scenario actually uses two libraries in the Spire.Office package. They're Spire.Doc for Java and Spire.XLS for Java. The former is used to read and extract content from a Word document, and the latter is used to create an Excel document and write data in the specific cells. To make this code example easy to understand, we created the following three custom methods that preform specific functions.

• exportTableInExcel() - Export data from a Word table to specified Excel cells.
• copyContentInTable() - Copy content from a table cell in Word to an Excel cell.
• copyTextAndStyle() - Copy text with formatting from a Word paragraph to an Excel cell.

The following steps demonstrate how to export data from a Word document to a worksheet using Spire.Office for Java.

• Create a Document object to load a Word file.
• Create a Workbook object and add a worksheet named "WordToExcel" to it.
• Traverse though all the sections in the Word document, traverse through all the document objects under a certain section, and then determine if a document object is a paragraph or a table.
• If the document object is a paragraph, write the paragraph in a specified cell in Excel using coypTextAndStyle() method.
• If the document object is a table, export the table data from Word to Excel cells using exportTableInExcel() method.
• Auto fit the row height and column width in Excel so that the data within a cell will not exceed the bound of the cell.
• Save the workbook to an Excel file using Workbook.saveToFile() method.
