- 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.
- Texinfo is a markup language and file format used to produce both online documentation and printed manuals from a single source file. It is the official documentation format of the GNU Project, allowing output to formats like HTML, PDF, and Info. The .texi extension marks source files written in this markup before processing by the texinfo toolchain.
