{
    License license = new License();
    license.SetLicense(Constants.LicensePath);
    Console.WriteLine("License set successfully.");
}
else
{
    Console.WriteLine("\nWe do not ship any license with this example. " +
                      "\nVisit the GroupDocs site to obtain either a temporary or permanent license. " +
                      "\nLearn more about licensing at https://purchase.groupdocs.com/faqs/licensing. " +

// Load a DOCX file
string filePath = "path/to/your/document.docx";
EditableDocument document = Editor.FromFile(filePath);

string content = document.GetContent();
content = content.Replace("old text", "new text");
// Apply the changes back to the document
EditableDocument editedDocument = EditableDocument.FromContent(content);

Here, we retrieve the content of the document, make some modifications, and then apply those changes back to the document.

Step 5: Save the Edited Document

After editing the document, the final step is to save the changes. You can save the document in the original format or convert it to another supported format.

// Save the edited document
string outputPath = "path/to/your/edited_document.docx";
