PST

Personal Storage File

The PST (Outlook Personal Information Store) file format is a proprietary file format used by Microsoft Outlook to store email messages, calendar events, contacts, tasks, and other data locally on a user's computer. It is primarily associated with Microsoft Outlook but can also be accessed using tools like Microsoft Exchange, Outlook Express, and third-party applications such as Kernel for PST Viewer or SysTools PST Repair. The format organizes data in a hierarchical structure, supporting advanced features like encryption, compression, and the ability to store large amounts of data, making it suitable for both personal and professional use.

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.
