NSF

Lotus Notes Database

The NSF (Lotus Notes Storage Format) is a proprietary file format used by IBM Notes (formerly Lotus Notes) to store emails, documents, calendars, and other data in a database-like structure. It is primarily accessed through IBM Notes or HCL Notes, but third-party tools like NSF to PST converters or NSF viewers can also read and extract data. The format supports advanced features such as rich text, attachments, encryption, and replication, making it a robust solution for enterprise-level collaboration and data management.

XLSX

Microsoft Excel Open XML Spreadsheet

XLSX is a widely used file format for spreadsheets, developed by Microsoft as part of the Office Open XML standard, succeeding the older XLS format. It is supported by Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications, ensuring cross-platform compatibility. The format is based on XML and stored in a compressed ZIP container, enabling features like advanced formulas, charts, conditional formatting, and support for large datasets while maintaining smaller file sizes compared to its predecessor.
