You can easily view emails from Outlook data files in HTML on the cloud. You can share filtered email messages or emails from a specific folder to view in the browser. As a Python developer, you can render OST data files in HTML programmatically on the cloud. In this article, you will learn how to render Outlook data files to HTML using a REST API in Python.
Document Viewer REST API and Python SDK
I will be using the Python SDK of GroupDocs.Viewer Cloud API for the rendering of OST files to HTML. It allows you to programmatically render all sorts of popular documents such as Word, Excel, Powerpoint, and image file formats. It also provides .NET, Java, PHP, Ruby, Android, and Node.js SDKs as its document viewer family members for the Cloud API.
You can install GroupDocs.Viewer Cloud to your Python project using the following command in the console:
pip install groupdocs_viewer_cloud
Please get your Client ID and Client Secret from the dashboard before you start following the steps and available code examples. Once you have your ID and secret, add in the code as shown below:
Render Outlook Data Files To HTML using a REST API in Python
You can render Outlook emails in HTML by following the simple steps mentioned below:
- Upload the OST file to the Cloud
- Render OST to HTML
- Download the rendered HTML file
Upload the Document
Firstly, upload the OST file to the Cloud using the code example given below:
As a result, the uploaded OST file will be available in the files section of your dashboard on the cloud.
Render OST to HTML in Python
Please follow the steps mentioned below to render emails from Outlook data file to HTML programmatically.
- Create an instance of View API
- Define ViewOptions
- Set the OST file path
- Set view_format as “HTML”
- Define HTMLOptions
- Define OutlookOptions
- Set the folder to “Inbox”
- Create a view request by calling the CreateViewRequest method
- Get a response by calling the create_view method
The following code sample shows how to render Outlook email data to HTML using a REST API.
You may customize the rendering of the OST file by applying the following options:
- Filter messages inside folders by some text value from message content
view_options.render_options.outlook_options.text_filter = "Microsoft"
- Filter by part of the sender’s or recipient’s address
view_options.render_options.outlook_options.address_filter = "susan"
- Render by setting a maximum limit of items to show
view_options.render_options.outlook_options.max_items_in_folder = 10
Download the Rendered File
The above code sample will save the rendered HTML file on the cloud. You can download it using the following code sample:
Please try the following free online OST rendering tool, which is developed using the above API. https://products.groupdocs.app/viewer/ost
