ONE

Microsoft OneNote File Format

The ONE file format, also known as OneNote Document, it was developed by Microsoft for storing digital notes, including text, images, audio, and other multimedia content, primarily used in Microsoft OneNote. It is supported by Microsoft OneNote across platforms, including Windows, macOS, iOS, and Android, and can be accessed via web-based OneNote or third-party tools with limited compatibility. The format organizes notes into hierarchical sections and pages, supports advanced features like embedded files, handwriting recognition, and cloud synchronization, making it ideal for collaborative and multi-device workflows.

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.
