XLSX is the modern file format used by Microsoft Excel, based on the Office Open XML standard, for storing spreadsheet data. It supports larger datasets, more complex formulas, charts, and styles, widely used in data analysis, financial reports, and business presentations. Compared to the older XLS format, XLSX offers better compatibility and enhanced security, making it suitable for various applications.

ODS is the OpenDocument Spreadsheet format, based on the XML standard, used for storing spreadsheet data. It was developed by OASIS and is widely supported by open-source office suites such as LibreOffice Calc and OpenOffice Calc. ODS files support complex formulas, charts, images, and other multimedia elements, making them suitable for creating high-quality spreadsheets, financial reports, and data analysis. Compared to traditional XLS or XLSX files, ODS offers better cross-platform compatibility and adherence to open standards, ensuring consistent formatting and layout across different operating systems and applications. Additionally, ODS files are typically smaller in size and faster to load, making them ideal for handling large datasets.
