- 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.
- OPML (Outline Processor Markup Language) is an XML-based format used to exchange outline-structured information. It is most commonly used to share lists of web feed subscriptions (such as RSS or Atom feeds) between feed readers and aggregators.
