How to Identify and Manage File formats Unsupported by .NET Core Word?

Syncfusion Essential DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. In this article, you will learn how to identify and manage file formats unsupported by DocIO using C#.

Refer to the documentation, to know about supported file formats in DocIO. If you use an older or unsupported format, convert it to a supported format to avoid errors. Otherwise, you will get this exception: This file format is not supported. To avoid this, always use the DocIO supported file formats listed above.

Steps to identify and manage file formats not supported by DocIO:

1. Create a new .NET Core console application project.
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in the Program.cs file
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO; 

4. Use the following code example to identify file formats not supported by DocIO.
   C#

// Get all files from the directory
string[] files = Directory.GetFiles(Path.GetFullPath(@"Data/"));
// Loop through each file in the directory
foreach (string filePath in files)
{
   using (FileStream inputStream = new FileStream(filePath, FileMode.Open, FileAccess.Read))
   {
       try
       {
           // Try to open the file using Syncfusion DocIO
           using (WordDocument doc = new WordDocument(inputStream, FormatType.Automatic))
           {
               // Successfully opened the document
               Console.WriteLine("Supported format" + filePath);
           }
       }
       catch (Exception ex)
       {
           // Check if the exception message matches the unsupported format message
           if (ex.Message.Contains("This file format is not supported"))
           {
               // If the file format is not supported, print it to the console
               Console.WriteLine("Unsupported format: " + filePath);
           }
           else
           {
               // If some other exception occurs, handle it
               Console.WriteLine($"Error opening file {filePath}: {ex.Message}");
           }
       }
   }
}

Take a moment to peruse the documentation where you can find basic Word document processing options along with features like mail merge, merge, split, and compare Word documents, find and replace text in the Word document, protect the Word documents, and most importantly, the PDF and Image conversions with code examples.
