Convert to MS Office from any file in C#
Nutrient .NET SDK (formerly GdPicture.NET) supports converting 100+ file types to Word, Excel, or PowerPoint.
100+ supported input file types
- MS Office (Word, Excel, PowerPoint)
- PDF, PDF/A
- HTML, MHT, MHTML
- Email (MSG, EML)
- Images (raster and vector)
- Text (TXT and RTF) and OpenDocument (ODT)
- CAD (DXF)
- RAW Camera Image Formats (3FR, ARW, BAY, etc.)
For more information, refer to the full list of supported file types.
Converting PDF to MS Office
To convert PDF files to MS Office, refer to our separate PDF-to-Word, PDF-to-Excel, and PDF-to-PowerPoint guides.
Converting other file types to MS Office
To save a file to Word, Excel, or PowerPoint format, first use the SaveAsPDF
method of the GdPictureDocumentConverter
class to convert it to PDF. Then use the SaveAsDOCX
method to convert it to a DOCX, the SaveAsXLSX
method to convert it to XLSX, or the SaveAsPPTX
method to convert it to PPTX.
The SaveAsPDF
method uses the following parameters:
Stream
, or the overloadFilePath
— A stream object where the current document is saved to as a DOCX file. This stream object must be initialized before it can be sent into this method, and it should stay open for subsequent use. If the output stream isn’t open for both reading and writing, the method will fail, returning theGdPictureStatus.InvalidParameter
status, which is the file path where the converted file will be saved. If the specified file already exists, it’ll be overwritten. You have to specify a full file path, including the file extension.Conformance
— A member of thePdfConformance
enumeration. This specifies the required conformance to the PDF or PDF/A standard of the saved PDF document. You can use the value ofPdfConformance.PDF
to save the file as a common PDF document.
The SaveAsDOCX
, SaveAsXLSX
, and SaveAsPPTX
methods use the following parameter:
Stream
, or the overloadFilePath
Note that the output stream should be open for both reading and writing and closed/disposed of by the user once processing is complete using the CloseDocument
method.
How to convert any file to MS Office
- Create a
GdPictureDocumentConverter
object. - Convert the source file to PDF with
GdPictureDocumentConverter.SaveAsPDF(Stream, PdfConformance)
. Recommended: Specify the source document format with a member of theDocumentFormat
enumeration. - Load the newly generated PDF file by passing its path to the
LoadFromFile
method (this method only supports PDF documents). - Save the PDF file as a DOCX using
SaveAsDOCX
, as an XLSX usingSaveAsXLSX
, or as a PPTX usingSaveAsPPTX
.
The following example converts and saves an RTF document to a DOCX file (it can also be saved as a stream):
using GdPictureDocumentConverter converter = new();
using Stream inputStream = File.Open(@"input.rtf", System.IO.FileMode.Open);using Stream outputStream = new MemoryStream();
GdPictureStatus status = converter.ConvertToPDF(inputStream, GdPicture14.DocumentFormat.DocumentFormatRTF, outputStream, PdfConformance.PDF1_5);if (status != GdPictureStatus.OK){ throw new Exception(status.ToString());}
status = converter.LoadFromStream(outputStream);if (status != GdPictureStatus.OK){ throw new Exception(status.ToString());}
status = converter.SaveAsDOCX("output.docx");if (status != GdPictureStatus.OK){ throw new Exception(status.ToString());}
Console.WriteLine("The input document has been converted to a docx file");

Optional file type configuration properties
The following file types have optional configuration properties for greater precision:
Optional PDF configuration properties
Optionally, configure the conversion with the following properties of the GdPictureDocumentConverter
object:
PdfBitonalImageCompression
is a member of thePdfCompression
enumeration that specifies the compression scheme used for bitonal images in the output PDF file.PdfColorImageCompression
is a member of thePdfCompression
enumeration that specifies the compression scheme used for color images in the output PDF file.PdfEnableColorDetection
is a Boolean value that specifies whether to use automatic color detection during the conversion that preserves image quality and reduces the output file size.PdfEnableLinearization
is a Boolean value that specifies whether to linearize the output PDF to enable Fast Web View mode.PdfImageQuality
is an integer from 0 to 100 that specifies the image quality in the output PDF file.
The example below creates a PDF document from an RTF file with a custom configuration:
using GdPictureDocumentConverter gdpictureDocumentConverter = new GdPictureDocumentConverter();// Load the source document.gdpictureDocumentConverter.LoadFromFile(@"C:\temp\source.rtf", GdPicture14.DocumentFormat.DocumentFormatRTF);// Configure the conversion.gdpictureDocumentConverter.PdfColorImageCompression = PdfCompression.PdfCompressionJPEG;gdpictureDocumentConverter.PdfImageQuality = 50;// Save the output in a new PDF document.gdpictureDocumentConverter.SaveAsPDF(@"C:\temp\output.pdf");
Using gdpictureDocumentConverter As GdPictureDocumentConverter = New GdPictureDocumentConverter() ' Load the source document. gdpictureDocumentConverter.LoadFromFile("C:\temp\source.rtf", GdPicture14.DocumentFormat.DocumentFormatRTF); ' Configure the conversion. gdpictureDocumentConverter.PdfColorImageCompression = PdfCompression.PdfCompressionJPEG gdpictureDocumentConverter.PdfImageQuality = 50 ' Save the output in a new PDF document. gdpictureDocumentConverter.SaveAsPDF("C:\temp\output.pdf")End Using
