C++ API to Export EML to ODT
Transform EML to ODT within C++ application without requiring Microsoft Word or Outlook
Why to Convert
As a C++ developer, you may need to add email conversion features inside your applications. This could be for a variety of reasons, such as to make the emails easier to read, to make them more compatible with other applications, or to make them easier to store and access.
How Aspose.Total Helps for EML to ODT Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that can help you to easily convert emails from the EML file format to HTML. This can be done using the Aspose.Email for C++ API. Once the emails have been converted to HTML, you can then use the Aspose.Words for C++ API to export the HTML to ODT. Both of these APIs are included in the Aspose.Total for C++ package, making it easy to access both of them in one place.
C++ API to Convert EML to ODT
- Open EML file using MailMessage class reference
- Convert EML to HTML by using Save member function
- Load HTML by using Document class
- Save the document to ODT format using Save method and set Odt as SaveFormat
Get Started with C++ File Format APIs
Install from command line as nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with Install-Package Aspose.Total.Cpp.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load the EML file to be converted
System::SharedPtr<MailMessage> msg = MailMessage::Load(u"sourceFile.eml");
// save EML as a HTML
msg->Save(u"HtmlOutput.html", SaveOptions::get_DefaultHtml());
// load HTML with an instance of Document
System::SharedPtr<Document> doc = System::MakeObject<Document>(u"HtmlOutput.html");
// call save method while passing Odt as save format
doc->Save(u"convertedFile.Odt");
Parse EML File via C++
Not only you can convert your EML to ODT, but you can read, manipulate, and parse EML document. You can get subject, address, body, recipients information of the email by using MapiMessage class of Aspose.Email for C++ API. For example, you can check for a specific sender email for the conversion by using get_SenderEmailAddress() property.
// create an instance of MapiMessage from file
System::SharedPtr<MapiMessage> msg = MapiMessage::FromFile(dataDir + L"message.eml");
// get subject
System::Console::WriteLine(System::String(L"Subject:") + msg->get_Subject());
// get from address
System::Console::WriteLine(System::String(L"From:") + msg->get_SenderEmailAddress());
// get body
System::Console::WriteLine(System::String(L"Body") + msg->get_Body());
// get recipients information
System::Console::WriteLine(System::String(L"Recipient: ") + msg->get_Recipients());
C++ API to Restrict ODT File Format Editing
You can also add document protection features in your app while exporting the document from EML to ODT. Adding protection to your document is a simple process, as all you need to do is apply the protection method to your document. You can set protection type to ReadOnly to restrict the user to edit the document.
// create a new document and protect it with a password.
auto doc = System::MakeObject<Document>();
// apply Document Protection.
doc->Protect(ProtectionType::ReadOnly, u"password");
// save the document.
doc->Save(u"DocumentProtection.PasswordProtection.Odt");
