Let’s give an example in programming language C# to show how it is easy to convert all MS Office documents into PDF format:

         //Convert Word Excel PowerPoint to PDF files
         SautinSoft.UseOffice u = new SautinSoft.UseOffice();

         //directory which contains Word, Excel, PowerPoint files: *.doc, *.docx, *.rtf, *.txt, *.xls, *.xlsx, *.csv, *.ppt, *.pptx
         string pathToOfficeDocs = @"c:\Docs\";

         //Prepare UseOffice .Net, loads MS Word, Excel, PowerPoint into memory
         int ret = u.InitOffice();

         //Can't load MS Office in memory
         if (ret==111)
            return;
      
         //1. Get list of MS Office files from directory         
         ArrayList documents = new ArrayList();
         string[] filters = new string[] { "*.doc", "*.docx", "*.rtf", "*.txt", "*.xls", "*.xlsx", "*.csv", "*.ppt", "*.pptx" };

         foreach (string filter in filters)
         {
            documents.AddRange(Directory.GetFiles(pathToOfficeDocs, filter));
         }

         //2. Convert all Word, Excel, PorwerPoint files to PDF from specifed directory

         string ext ="";
         string outPutFile = "";
         for (int x=0; x< documents.Count; x++)
         {
            SautinSoft.UseOffice.eDirection direction = SautinSoft.UseOffice.eDirection.DOC_to_PDF;
            ext = Path.GetExtension((string)documents[x]).ToLower();

            if (ext.IndexOf("doc")>0)
               direction = SautinSoft.UseOffice.eDirection.DOC_to_PDF;
            else if (ext.IndexOf("rtf")>0)
               direction = SautinSoft.UseOffice.eDirection.RTF_to_PDF;         
            else if (ext.IndexOf("txt")>0)
               direction = SautinSoft.UseOffice.eDirection.RTF_to_PDF;
            else if (ext.IndexOf("xls")>0)
               direction = SautinSoft.UseOffice.eDirection.XLS_to_PDF;
            else if (ext.IndexOf("csv")>0)
               direction = SautinSoft.UseOffice.eDirection.XLS_to_PDF;
            else if (ext.IndexOf("ppt")>0)
               direction = SautinSoft.UseOffice.eDirection.PPT_to_PDF;

            outPutFile = Path.Combine(Path.GetDirectoryName((string)documents[x]),Path.GetFileNameWithoutExtension((string)documents[x]));
            outPutFile+=".pdf";            
            u.ConvertFile((string)documents[x],outPutFile, direction);
         }

         u.CloseOffice();
