Basic Initialization and Setup

Once installed, initialize your project by creating an Editor instance:

import com.groupdocs.editor.Editor;
import com.groupdocs.editor.options.WordProcessingLoadOptions;

String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
Editor editor = new Editor(inputFilePath, new WordProcessingLoadOptions());

With these steps completed, you’re ready to implement the key features of GroupDocs.Editor.

Implementation Guide

Load a Document

Overview: Begin by loading your document. This foundational step allows all subsequent modifications and saves.

Step 1: Import Required Packages

import com.groupdocs.editor.Editor;
import com.groupdocs.editor.EditableDocument;

Step 2: Initialize the Editor with Your Document

Create an instance of Editor using the file path to your document:

String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
Editor editor = new Editor(inputFilePath, new WordProcessingLoadOptions());
EditableDocument defaultWordProcessingDoc = editor.edit();

This code loads the specified Word document into your Java application.

Edit Document Content

Overview: Modify content by working with its HTML representation. This approach provides flexibility in editing text elements like subtitles or paragraphs.

Step 3: Retrieve and Modify Embedded HTML

Extract and edit the document’s embedded HTML:

String allEmbeddedInsideString = defaultWordProcessingDoc.getEmbeddedHtml();
String modifiedContent = allEmbeddedInsideString.replace("Subtitle", "Edited subtitle");

This snippet demonstrates how you can search for specific text (“Subtitle”) and replace it with new content (“Edited subtitle”).

Save Document as RTF

Overview: After editing, save the document in Rich Text Format (RTF).

Step 4: Configure Save Options

Set up WordProcessingSaveOptions to specify RTF format:

import com.groupdocs.editor.options.WordProcessingSaveOptions;
import com.groupdocs.editor.formats.WordProcessingFormats;

String outputRtfPath = "YOUR_OUTPUT_DIRECTORY/editedDoc.rtf";
WordProcessingSaveOptions rtfSaveOptions = new WordProcessingSaveOptions(WordProcessingFormats.Rtf);

Step 5: Save the Document

Use Editor.save() to write changes to a file:

EditableDocument editedDocRtf = EditableDocument.fromMarkup(modifiedContent, null);
editor.save(editedDocRtf, outputRtfPath, rtfSaveOptions);
editedDocRtf.dispose();
editor.dispose();

Save Document as DOCM through a Stream

Overview: Save your document in the DOCM format using an OutputStream for enhanced flexibility.

Step 6: Configure DOCM Save Options

WordProcessingSaveOptions docmSaveOptions = new WordProcessingSaveOptions(WordProcessingFormats.Docm);

Step 7: Write to a Stream

Use a stream to save your document:

import java.io.ByteArrayOutputStream;
import java.io.OutputStream;

String outputDocmPath = "YOUR_OUTPUT_DIRECTORY/editedDoc.docm";
try (OutputStream outputStream = new ByteArrayOutputStream()) {
    editor.save(editedDocDocm, outputStream, docmSaveOptions);
}

Save Document as Plain Text

Overview: Export your document as a plain text file for simple content extraction.

Step 8: Configure Text Save Options

Set the encoding and layout preservation options:

import com.groupdocs.editor.options.TextSaveOptions;
import java.nio.charset.StandardCharsets;

TextSaveOptions textSaveOptions = new TextSaveOptions();
textSaveOptions.setEncoding(StandardCharsets.UTF_8);
textSaveOptions.setPreserveTableLayout(true);

Step 9: Save as Plain Text

String outputTxtPath = "YOUR_OUTPUT_DIRECTORY/editedDoc.txt";
editor.save(editedDocTxt, outputTxtPath, textSaveOptions);

Practical Applications

  1. Automated Report Generation: Automate monthly report generation by integrating this solution with your data sources.
  2. Template Customization: Dynamically update Word templates for marketing materials or legal documents based on user input.
  3. Document Translation Workflows: Streamline multilingual document translation processes using automated text replacements.
