Implementation Guide

Feature: Join Multiple Documents of Different Types

This feature illustrates how to merge documents with varying file types using GroupDocs.Merger. Let’s break down the process step-by-step.

Step 1: Define Input and Output Paths

Set up your input and output directories for document management:

string documentDirectory = @"YOUR_DOCUMENT_DIRECTORY";
string outputDirectory = @"YOUR_OUTPUT_DIRECTORY";

// Example file paths
string pdfFilePath = Path.Combine(documentDirectory, "sample.pdf");
string docxFilePath = Path.Combine(documentDirectory, "sample.docx");
string xlsxFilePath = Path.Combine(documentDirectory, "sample.xlsx");
string pptxFilePath = Path.Combine(documentDirectory, "sample.pptx");

// Output path for the merged document
string outputPath = Path.Combine(outputDirectory, "merged_document.pdf");

Step 2: Initialize Merger

Start by initializing the Merger object with the primary PDF file. This acts as the base document to which other files will be appended:

using (Merger merger = new Merger(pdfFilePath))
{
    // The following steps involve joining additional documents.
}

Step 3: Join Additional Documents

Sequentially add Word, Excel, and PowerPoint files to your primary PDF:

  • Join Word Document:

    merger.Join(docxFilePath); // Appends the Word document.

  • Join Excel Spreadsheet:

    merger.Join(xlsxFilePath); // Adds the Excel spreadsheet.

  • Join PowerPoint Presentation:

    merger.Join(pptxFilePath); // Integrates the PowerPoint file.

Step 4: Save the Merged Document

Finally, save your newly merged document into a single PDF file:

merger.Save(outputPath);

Troubleshooting Tips

  • File Path Errors: Ensure all file paths are correctly specified and accessible.
  • License Issues: Validate that your GroupDocs license is properly configured to avoid limitations.
