EPPlus is a powerful and versatile .NET library for managing and manipulating Microsoft Excel files using the Office Open XML (OOXML) format. It is a lightweight and efficient library that is easy to use and can be integrated into a wide range of applications. It allows developers to create, read and modify spreadsheets without dependencies on any other library. Features include pivot tables, styling, VBA/Form controls, conditional formatting, charts, tables, formula calculation, data validation, pictures/shapes, and more.

​The EPPlus v8.0.1 update enhances the visualization of spreadsheet data by introducing the ability to insert images directly into individual worksheet cells. This feature is particularly beneficial for creating more informative and engaging spreadsheets, such as including product images in inventory lists or embedding charts alongside relevant data. The new functionality supports various image formats, such as PNG, JPG and GIF, and integrates with the IMAGE function, so you can add local images as well as download images from the web via URLs.

EPPlus is licensed per developer and is available as both perpetual licenses and subscription based licenses with periods of 1 year and 2 years, which include support and upgrades. See our EPPlus licensing page for full details.

MX (Mail Exchange) record support enables applications to programmatically retrieve and interact with DNS records that define how email should be routed for a domain. This capability is essential for building features such as email validation, automated mail routing, or diagnostics tools that verify domain configurations. By integrating MX record handling directly into their app, developers can streamline workflows that depend on accurate mail server information, improve reliability of outbound email systems, and enhance application logic that requires verification of recipient domains.

Several .NET communications and messaging components offer MX record features including:

• IPWorks .NET Edition by /n software enables querying of Mail Exchange (MX) records from DNS servers, facilitating the identification of mail servers.
• Rebex Mail Pack provides functionality to resolve MX records, allowing applications to determine the appropriate mail servers for direct email delivery.
• PowerTCP Sockets for .NET by Dart Communications offers MX record lookup capabilities through its DNS component, enabling the resolution of mail server names.
