How to merge ODT files

GroupDocs.Merger allows developers to merge ODT files when it’s needed to organize multiple ODT files into single document or send fewer attachments etc. And you can do this without any third-party software or manual work involved. With GroupDocs.Merger it is possible to combine ODT documents of any size and structure - all text, images, tables, graphs, forms and other content will be preserved.

The following example demonstrates how to merge ODT files with several lines of C# code:

  • Create an instance of Merger class and pass source ODT file path as a constructor parameter. You may specify absolute or relative file path as per your requirements.
  • Add another ODT file to merge with Join method. Repeat this step for other ODT documents you want to merge.
  • Call Merger class Save method and specify the filename for the merged ODT file as parameter.
// Load the source ODT file
using (Merger merger = new Merger(@"c:\sample1.odt"))
{
    // Add another ODT file to merge
    merger.Join(@"c:\sample2.odt");
    // Merge ODT files and save result
    merger.Save(@"c:\merged.odt");
}

NOTE: You may merge other Open Document formats like ODP, OTP and ODS in the same way as shown above. For this provide files by specifying their names with extension.
