How We Can See File Extension in Excel Windows

February 13, 2023

The extension of an Excel file provides you with important information about that file before you open it. It also lets you organize the files you save into your directories as template files, macro-enabled files, and more. With just a glance at the Excel file extension, you know more about the Excel file and what it’s used for.

Excel file extensions tell you:

  1. Whether macros or VBA are included.

  2. If the file was saved with an older version of Excel.

  3. Whether the file format is based on XML documents or binary.

  4. The general legacy version of the file was saved.

  5. Whether the file is a template.

Excel File Extensions By Version

The first group of file extensions are related primarily to which version of Excel the worksheet was saved with. The following extension types are connected to the Excel versions shown here:

  1. Excel 97-2003: *.xls

  2. Excel 97-2003 template: *.xlt

  3. XML Spreadsheet 2003: *.xml

  4. Microsoft Excel 5.0/95 Workbook: *.xls
