What is the Extension Name of a Microsoft Excel 2010 File?

Question

What is the extension name of a Microsoft Excel 2010 file?

1. Xls
2. Ppt
3. Xlsx
4. Doc
5. Exe

Answer

C. Xlsx

Explanation

Let’s take a look at from what program each of the extension names in the answer choices mainly comes.

• Xls = Microsoft Excel 1997-2003
• Ppt = Microsoft PowerPoint
• Xlsx = Microsoft Excel 2007 and later
• Doc = Microsoft Word 1997-2003
• Exe = Software

Since Microsoft Excel 2010 is an Excel version later than Microsoft Excel 2007, the answer to the question here is xlsx (although Excel 2010 can produce an xls file too, xlsx is its main file extension).
