Loading a Word Document with Password

Overview

This feature allows seamless loading of password-protected Word documents in your Java application.

Step-by-Step Implementation

Step 1: Define the path and load options for your document.

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

public class LoadWordDocument {
    public static void main(String[] args) throws Exception {
        String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/sample_legacy_form_fields.docx";
        
        InputStream fs = new FileInputStream(inputFilePath);
        
        WordProcessingLoadOptions loadOptions = new WordProcessingLoadOptions();
        loadOptions.setPassword("some_password_to_open_a_document");
        
        Editor editor = new Editor(fs, loadOptions);
    }
}

• Explanation: The WordProcessingLoadOptions class specifies the document’s password. If your document isn’t protected, this step can be skipped.
