- Description
- An XLSX file is an Excel spreadsheet created by Microsoft Excel or another spreadsheet program, such as OpenOffice Calc or Apple Numbers. It stores data in worksheets, which contain cells arranged in a grid of rows and columns, and may also contain charts, mathematical functions, styles, and formatting. XLSX files are commonly used to store financial data and to create simple or complex mathematical models.
- A RAR file is an archive that contains one or more files compressed with RAR compression. It uses a higher compression ratio than typical ZIP compression and incorporates a proprietary compression algorithm that is now used by other compressors, including 7-Zip for its .7Z files. RAR files may be extracted using a variety of programs.
