What is an XLSX file?
The XLSX format is the default XML-based spreadsheet file introduced in Microsoft Office 2007, adhering to the Office Open XML (OOXML) standard (ECMA-376 and ISO/IEC 29500). It replaces the binary BIFF structure of legacy XLS files with a ZIP-compressed container holding individual XML files for workbook data, worksheet structure, and metadata. By design, XLSX files strictly exclude Visual Basic for Applications (VBA) macros to prevent malware propagation, distinguishing them from the macro-enabled XLSM format.
How to open an XLSX file
As an industry-standard open format, XLSX is supported natively by Microsoft Excel, Apple Numbers, and Corel Quattro Pro. Cross-platform open-source suites like LibreOffice and Apache OpenOffice provide full read/write capabilities. Cloud-based platforms, including Google Sheets and Microsoft Excel for the Web, allow direct editing in a browser without local software installation.

What is a GIF file?
The Graphics Interchange Format (GIF) is a bitmap image format developed by CompuServe in 1987, distinguished by its use of the Lempel-Ziv-Welch (LZW) lossless data compression algorithm. It supports up to 8 bits per pixel, allowing a palette of 256 distinct colors selected from the 24-bit RGB color space. The GIF89a specification, introduced in 1989, added support for transparent backgrounds, animation delays, and application extensions, establishing it as a standard for simple web animations and low-color graphics.
How to open a GIF file
GIF files possess near-universal compatibility and can be opened natively by all modern web browsers (Chrome, Firefox, Safari, Edge) and default operating system viewers like Microsoft Photos and Apple Preview. No third-party software is typically required for viewing. For editing frame-by-frame animations or modifying color palettes, raster graphics editors such as GIMP, Adobe Photoshop, or online tools like Ezgif are required.
