Implementation Guide

Load a Word Document

Overview: This feature lets you load a DOCX file, preparing it for merging operations.

Step-by-step:

  1. Specify the Path: Begin by defining the path to your document directory.
    String sourceFilePath = "YOUR_DOCUMENT_DIRECTORY/sample1.docx";
  2. Create Merger Object: Initialize a Merger object with the specified DOCX file.
    import com.groupdocs.merger.Merger;

public class LoadWordDocument {
    public static void main(String[] args) throws Exception {
        Merger merger = new Merger(sourceFilePath);
        // The DOCX file is now loaded and ready for merging.
    }
}

Define Word Join Options

Overview: Configure compliance settings to ensure the merged document adheres to specific standards.

Step-by-step:

  1. Create WordJoinOptions Instance: Set up options that dictate how documents will be joined.
    import com.groupdocs.merger.domain.options.WordJoinOptions;
import com.groupdocs.merger.domain.options.WordJoinCompliance;

public class DefineWordJoinOptions {
    public static void main(String[] args) {
        WordJoinOptions joinOptions = new WordJoinOptions();
        joinOptions.setCompliance(WordJoinCompliance.Iso29500_2008_Strict);
        // Compliance settings are now configured.
    }
}

Merge Word Documents

Overview: Combine two or more Word documents into a single file using predefined options.

Step-by-step:

  1. Load Source Files: Specify paths for your source and output files.
    String sourceFilePath1 = "YOUR_DOCUMENT_DIRECTORY/sample1.docx";
String sourceFilePath2 = "YOUR_DOCUMENT_DIRECTORY/sample2.docx";
String outputPath = "YOUR_OUTPUT_DIRECTORY/merged.docx";
  2. Initialize Merger and Merge: Use the Merger object to combine documents with compliance settings.
    import com.groupdocs.merger.Merger;

public class MergeWordDocuments {
    public static void main(String[] args) throws Exception {
        Merger merger = new Merger(sourceFilePath1);
        merger.join(sourceFilePath2, new WordJoinOptions());
        merger.save(outputPath);
        // Documents are now merged and saved.
    }
}
