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.

XLSM

Microsoft Excel Macro-Enabled Spreadsheet

XLSM is a file format used for Excel spreadsheets that support macros, enabling automation and advanced functionality within the document. It is primarily used with Microsoft Excel but can also be opened by other spreadsheet applications like LibreOffice Calc and Google Sheets with limited macro support. The format is based on the Open XML standard, storing data, formulas, and VBA (Visual Basic for Applications) macros in a compressed ZIP container, allowing for efficient storage and advanced features like conditional formatting, pivot tables, and embedded macros.
