Why to Convert OST to EPUB

For a Python developer, who is trying to add a OST to EPUB conversion feature within application, it is important to understand why this conversion is necessary. OST is an Outlook data file that stores emails, contacts, tasks, calendars, and other items. It is used to store data locally on the computer, and is not compatible with other applications. EPUB is an open standard for digital books, and is widely used for e-books. It is supported by many devices, including smartphones, tablets, and computers. Therefore, it is important to convert OST files to EPUB format in order to make the data accessible to a wider audience.

How Aspose.Total Helps for OST to EPUB Conversion

Aspose.Total for Python via .NET API can help to automate the conversion process. It is a full package of various APIs dealing different formats including Email, Images and Microsoft Word formats. Aspose.Words for Python via .NET and Aspose.Email for Python via .NET APIs that are part of Aspose.Total for Python via .NET package makes this conversion easy using Python. It is a two step process, firstly load Email and render it into HTML via Aspose.Email for Python via .NET. Secondly load the converted HTML using Aspose.Words for Python via .NET and save it into respective Word EPUB format. This process is simple and efficient, and can be used to quickly convert OST files to EPUB format.

How to Convert OST to EPUB in Python

  • Open the source OST file using MailMessage.load class
  • Call the save method while specifying output HTML file path and relevant HTML Save options as parameter. So your OST file is converted to HTML at the specified path
  • Now Load the saved HTML file using Document
  • Call the save method with relevant file path. So finally the OST is converted

Conversion Requirements

  • For OST to EPUB conversion, Python 3.5 or later is required
  • Reference APIs within the project directly from PyPI ( Aspose.Words and Aspose.Email )
  • Or use the following pip command pip install aspose.words and pip install Aspose.Email-for-Python-via-NET
