How to Convert PST Files to HTML Format
Converting PST files to HTML format using Aspose.Email for Java offers a convenient method to extract email content and display it in a web-friendly format. This conversion process allows users to easily access and view email messages in a browser or any HTML-compatible application. Users can also conveniently share email contents, archive important email communications, or integrate email data into web-based platforms or reporting systems. Aspose.Email for Java simplifies the conversion, enabling seamless access to email information in a universal and accessible format.
To implement PST to HTML conversion functionality into a Java application, the library offers the PersonalStorage class which is used to open a storage file, allowing access to its content and structure. The FolderInfo class represents a folder within the storage file and makes it possible to manipulate its content. The MapiMessage class provides developers with a comprehensive set of functionalities to work with email messages programmatically, enabling them to efficiently manage, manipulate, and interact with email data within their Java applications. The HtmlSaveOptions class defines options for saving MapiMessage objects as HTML files. It allows customization of the HTML output, such as specifying the resource rendering mode and using relative paths to store external resources like images or stylesheets. The ResourceRenderingMode enum class is used to determine how resources (e.g., images, attachments) are handled when saving an email message as an HTML file. The ‘SaveToFile’ mode, for example, is set to save the resources as separate files. The code sample below demonstrates the work of these classes in loading the PST file, extracting email messages from it, converting the messages to HTML format, and saving them as individual HTML files with appropriate resource handling options.

Steps to Convert PST to HTML via Java
Java programmers can easily convert PST file to HTML in just a few lines of code.
- Load the PST file with the PersonalStorage.fromFile method specifying the file path.
- Create the output directory if it does not already exist.
- Access the “Inbox” folder within the PST file by retrieving the FolderInfo object representing the Inbox folder with the method chain getRootFolder and getSubFolder .
- Iterate through each email message in the “Inbox” folder with the enumerateMapiMessages method.
- Use the save method to save each email message as an HTML file in the output directory, with resources saved as separate files.
System Requirements
Before running the Java conversion code, make sure that you have the following prerequisites.
- Microsoft Windows or a compatible OS with Java Runtime Environment for JSP/JSF Application and Desktop Applications.
- Get latest version of Aspose.Email for Java directly from Maven .
Convert PST to HTML - Java
// Open the PST file
PersonalStorage pst = PersonalStorage.fromFile(pstFilePath);
// Ensure the output directory exists
new File(outputDirectory).mkdirs();
// Get the Inbox folder from PST
FolderInfo inbox = pst.getRootFolder().getSubFolder("Inbox");
// Iterate through PST messages and save them as .html files
int count = 1;
for (MapiMessage msg : inbox.enumerateMapiMessages()) {
// Save each message as .html file
String htmlFilePath = outputDirectory + File.separator + "Message" + count + ".html";
HtmlSaveOptions htmlSaveOptions = new HtmlSaveOptions();
htmlSaveOptions.setResourceRenderingMode(ResourceRenderingMode.SaveToFile);
htmlSaveOptions.setUseRelativePathToResources(true);
msg.save(htmlFilePath, htmlSaveOptions);
System.out.println("Message " + count + " saved as: " + htmlFilePath);
count++;
}
What is PST File Format?
PST (Personal Storage Table) is a file format used by Microsoft Outlook to store email messages, contacts, calendars, tasks, and other mailbox items. PST files function as a data storage container that allows users to access and manage their email data within Outlook. These files can be created and saved locally on a user’s computer or stored on a network server. PST files are commonly used for backing up email data, archiving old messages, and migrating email data between different computers or email clients. Additionally, PST files can be password-protected to enhance data security and privacy.
What is HTML File Format?
HTML (Hypertext Markup Language) is a standard language used to create and format documents on the web. HTML files contain code that defines the structure and content of a web page, including text, images, links, and other elements. By using tags enclosed in angle brackets, web developers can create visually appealing and interactive web pages that can be displayed in web browsers. HTML files are saved with a “.html” or “.htm” extension and can be opened in any web browser. With the ability to combine HTML with CSS and JavaScript, developers can design dynamic and responsive websites for a better user experience.
