How to Open Files of Different Microsoft Excel Versions
An application often has to be able to open Microsoft Excel files created in different versions, for example, Microsoft Excel 95,97, or Microsoft Excel 2007/2010/2013/2016/2019 and Office 365 . You might need to load a file in any one of several formats, including XLS, XLSX, XLSM, XLSB, SpreadsheetML, TabDelimited or TSV, CSV, ODS and so on.
