Excel File Extension
 

What is the difference between the excel file extensions; *.xls, *.xlm, etc

Excel File Extension
 

XLM is a vestigial remain from Excel 4 and before. Back then a workbook
could have only one worksheet, and if that sheet was a "macro sheet" then it
was given the XLM extension to distinguish it from a regular worksheet
(XLS). While current Excel versions support XLMs for backward compatibility
there is no reason to use that extension any more.

Randy,

XLS files are normal workbooks.
XLM files are old version 4 macro sheets.
XLA files are add-ins.
XLT files are template workbook files.
XLW files are workspace files.
XLB files are toolbar customization files.
XLK files are back up files.

These are the only Excel related file extensions I am aware of.

Good list, Chip, better than I could do. One other old one was XLC - chart
files.

XLL is not an excel file extension. XLLs are Excel add-ins written in C.
