Microsoft Visio comes as part of the Microsoft Office suite and is used for diagramming and vector drawing applications. It is used to create several different types of diagrams including flow charts, UML diagrams, network diagrams, and a lot of others.

Visio file formats include file types such as VSDX, VSX, VTX, VDX, VSSX, VSTX, VSDM, VSSM, VSTM file formats that are saved to the disc when a user creates a project in Microsoft Visio.

With GroupDocs.Conversion you can easily convert your diagram document into another file format.
For example, VSDX to PDF conversion code snippet looks like this:

// Load the source VSDX file
using (Converter converter = new Converter("sample.vsdx"))
{
    // Set the convert options for PDF format
    PdfConvertOptions options = new PdfConvertOptions();
    // Convert to PDF format
    converter.Convert("converted.pdf", options);
}

Put it simply - you just load a diagram file into the Converter class, select the desired output format and GroupDocs.Conversion does all the rest.

Note

Refer to the API reference for more conversion options and customizations.

On the other hand, converting your diagram files to another diagram format is also quite simple and natural. The following code snippet shows how to convert a VSDX format to a VDW format in C# using GroupDocs.Conversion.

// Load the source VSDX file
using (Converter converter = new Converter("sample.vsdx"))
{
    // Set the convert options for VDW format
    var options = new DiagramConvertOptions {
        Format = DiagramFileType.Vdw;
    };
    // Convert to VDW format
    converter.Convert("converted.vdw", options);
}
