Installing via NuGet

The easiest way to install OfficeConverter is via NuGet.

In Visual Studio's Package Manager Console, simply enter the following command:

Install-Package OfficeConverter 

Converting a file from code

using (var converter = new Converter())
{
    converter.Convert(<inputfile>, <outputfile>);
}

Logging

From version 1.7.0 OfficeConverter uses the Microsoft ILogger interface (https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.logging.ilogger?view=dotnet-plat-ext-5.0). You can use any logging library that uses this interface.

OfficeConverter has some build in loggers that can be found in the OfficeConverter.Logger namespace.

For example

var logger = !string.IsNullOrWhiteSpace(<some logfile>)
                ? new ChromeHtmlToPdfLib.Loggers.Stream(File.OpenWrite(<some logfile>))
                : new ChromeHtmlToPdfLib.Loggers.Console();

The file '' seems to be corrupt

Hello I'm having this issue and I can't find a way to go around it.

The file 'OrderSummary.docx' seems to be corrupt, error: Object reference not set to an instance of an object.

I have Office Installed and activated and the library works just fine on my development environment. The issue is just after deploy.

I give permissions to the folder, I'm able to open the document on Word and manually convert.

Do you have any ideas?

With a windows service, Word file conversion error

By launching the conversion of a word document in a webservice, I have the error "The file 'doc.docx' seems to be corrupt, error: Object reference not set to an instance of an object".
Is there a special configuration for windows services? The same conversion from a console application works.

Getting Error while deploying my code to Azure App Service

I needed to convert .DOCX, .XLS, .XLXS file to .PDF file as part of my app. It's working fine on my local machine, as I have MS office installed on my system. But When I tried to deploy this application in Azure App Service plan, then it's not working as MS office is not available. I know we can install both our app and MS office in a VM and it will work. But is there any way we can deploy this app in Azure App Service or Containerize?

Perform prerequisites tests before launching pdf transformation

I was coping with #13 (pdf transformation not working when using OfficeConverter as a Window Service). As mentioned in this issue the two folders must be created :

• Windows x64: C:\Windows\SysWOW64\config\systemprofile\Desktop
• Windows x86: C:\Windows\System32\config\systemprofile\Desktop

I would say in my case that that System32 was causing the issue even if we are in a 64 bits OS server.

In our context we decided to use this project and to create a new module to run it as an executable (and not a service).

What I suggest is to create these folders before the transformation take place (what we did) :
It is important to disable the redirection before creating the system32 folder

        #region general prerequisites

        private static void CheckIfSystemProfileDesktopDirectoryExists()
        {
            if (NativeMethods.IsWindowsServer())
            {
                Wow64Interop.DisableWow64FSRedirection(IntPtr.Zero); // to really test system32 folder !
                var x86DesktopPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Windows),
                    @"System32\config\systemprofile\desktop");
                try
                {
                    Logger.WriteToLog("Prerequisites action: About to create x86 desktop path" + x86DesktopPath);
                    Directory.CreateDirectory(x86DesktopPath);
                    Logger.WriteToLog(x86DesktopPath + " created successfully");
                }
                catch (Exception exception)
                {
                    throw new OCConfiguration(
                        $"Prerequisites error: Can't create folder '{x86DesktopPath}' folder to perform PDF rendition",
                        exception);
                }
                Wow64Interop.Wow64RevertWow64FsRedirection(IntPtr.Zero);
                var x64DesktopPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Windows),
                    @"SysWOW64\config\systemprofile\desktop");

                try
                {
                    Logger.WriteToLog("Prerequisites action: About to create X64 desktop path" + x64DesktopPath);
                    Directory.CreateDirectory(x64DesktopPath);
                    Logger.WriteToLog(x64DesktopPath + " created successfully");
                }
                catch (Exception exception)
                {
                    throw new OCConfiguration(
                        $"Prerequisites error: Can't create folder '{x64DesktopPath}', folder is needed to perform PDF rendition",
                        exception);
                }
            }
        }

        #endregion
    }
    
    /// <summary>

is it possible to add a new feature to convert Msg to PDF?

Thanks for your great works, just wonder is there a plan to convert MSG to PDF. Thanks!

Exception thrown: 'System.AccessViolationException' in OfficeConverter.dll

This issue is coming while converting excel files to PDF. Is this a known bug or am I doing something wrong ?
I have already tried changing architecture to x86 while compiling the code. The same does not resolve the issue.

Exception thrown: 'System.AccessViolationException' in OfficeConverter.dll
An unhandled exception of type 'System.AccessViolationException' occurred in OfficeConverter.dll
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

// PrintCommunication = true // DO NOT REMOVE THIS LINE, NO NEVER EVER ... DON'T EVEN TRY IT
if the line above in excel.cs file is commented, then conversion works fine. I am using MS Office 2007.

cli_basetypes and rest types 64bit

Hi,

In my inhouse solution for open office i have very similar idea of converting odt to pdf. Problem occurs when i migrate solution to 64bit. I tried use your libs from x64 folder but i think there version mismatch which couse some core error in openoffice
https://github.com/Sicos1977/OfficeConverter/tree/master/OfficeConverter/CLI/x64

Question.
Where did you found these libs for x64?
I was unable to find and some forums mentioned that it dont even exist for x64.
