Implementation Guide

Merging Multiple XLT Files

This feature allows you to combine several Excel Template files into one. Let’s break it down step by step.

Overview

The goal is to load multiple .xlt files and merge them, saving the output in a new file.

Loading Files and Merging

  1. Load the First XLT File

    Begin by loading your first XLT file using GroupDocs.Merger:

    string sourceXltPath1 = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "sample.xlt");
using (var merger = new Merger(sourceXltPath1))
{
    // Additional steps will follow...
}

  2. Join the Second XLT File

    Add another file to merge:

    string sourceXltPath2 = Path.Combine("YOUR_DOCUMENT_DIRECTORY", "sample2.xlt");
merger.Join(sourceXltPath2);

  3. Save the Merged File

    Save your merged result as a new XLT file:

    string outputFile = Path.Combine(outputDirectory, "merged.xlt");
merger.Save(outputFile);

Troubleshooting Tips

  • Ensure all source files exist and paths are correctly specified.
  • Check for sufficient permissions to read/write in the directories.

Practical Applications

Merging XLT files can be useful in various scenarios:

  1. Financial Reporting: Combine monthly reports into a single file for quarterly analysis.
  2. Project Management: Merge templates used by different teams into one master template.
  3. Data Consolidation: Integrate data from various Excel templates for comprehensive datasets.

Integration with other systems, such as databases or web applications, can further enhance the utility of merged XLT files.
