Basic Initialization and Setup
Create an Editor instance that points to your source DOCX file:
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());
Now you’re ready to load, edit, and save documents.
Implementation Guide
Load a Document
Overview: Loading gives you an EditableDocument object that you can manipulate.
Step 1: Import Required Packages
import com.groupdocs.editor.Editor;
import com.groupdocs.editor.EditableDocument;
Step 2: Initialize the Editor with Your Document
String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
Editor editor = new Editor(inputFilePath, new WordProcessingLoadOptions());
EditableDocument defaultWordProcessingDoc = editor.edit();
Edit Document Content
Overview: The document is exposed as HTML, making text replacement straightforward.
Step 3: Retrieve and Modify Embedded HTML
String allEmbeddedInsideString = defaultWordProcessingDoc.getEmbeddedHtml();
String modifiedContent = allEmbeddedInsideString.replace("Subtitle", "Edited subtitle");
Save Document as RTF
Overview: After editing, you can export to Rich Text Format.
Step 4: Configure Save Options
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
EditableDocument editedDocRtf = EditableDocument.fromMarkup(modifiedContent, null);
editor.save(editedDocRtf, outputRtfPath, rtfSaveOptions);
editedDocRtf.dispose();
editor.dispose();
Save Document as DOCM through a Stream
Overview: Using a stream gives you more control over where the file ends up (e.g., cloud storage).
Step 6: Configure DOCM Save Options
WordProcessingSaveOptions docmSaveOptions = new WordProcessingSaveOptions(WordProcessingFormats.Docm);
Step 7: Write to a Stream
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: Exporting to plain text is useful for content indexing or simple data extraction.
Step 8: Configure Text Save 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
- Automated Report Generation – Pull data from databases, replace placeholders, and output a polished DOCX or RTF report.
- Template Customization – Dynamically fill marketing or legal templates based on user input.
- Document Translation Workflows – Replace text strings after machine translation to preserve formatting.
Performance Considerations
- Dispose of
EditableDocumentandEditorobjects as soon as you’re done to free native resources. - For very large files, process sections in chunks or use streaming APIs to keep memory usage low.
- Prefer
StringBuilderor efficient regex when performing bulk text replacements.
Common Issues and Solutions
| Issue | Solution |
|---|---|
| File not found / access denied | Verify the absolute path and ensure the Java process has read/write permissions. |
| Out‑of‑memory errors on big docs | Increase JVM heap (-Xmx) or split the document into smaller parts before editing. |
| Formatting lost after replace | Use the HTML markup API carefully; avoid replacing markup tags themselves. |
| License not applied | Call License license = new License(); license.setLicense("path/to/license.file"); before creating Editor. |
