Spreadsheet file created with Microsoft Excel, a program used to create spreadsheets; stores data in worksheets, which contain cells arranged in a grid of rows and columns; may also contain charts, mathematical functions, styles, and formatting; commonly used to store financial data and to create simple or complex mathematical models.Each cell in an XLSX spreadsheet may be formatted individually; for example, cells may have a number, text, currency, or other format as well as color, border style, custom font, and size; cells may reference other cells to compute a resulting value.
XLSX files are created using the Open XML standard, which was introduced in Microsoft Office 2007; they are stored as a compressed zip archive, which contains a collection of individual files; for example, spreadsheet data and properties are saved using XML files, including [Content_Types].xml, which describes the spreadsheet, and an XML file for each worksheet within the spreadsheet.
NOTE:
XLSX files can be opened in Excel 2007 or later; they are also backwards compatible with earlier versions of Excel via Open XML component support..xlsx打开.xlsx文件
