save this file with .xls extension.you you can remove the exclamation mark
With the introduction of Office 2007, Macro worksheets saved as .XLSM files show an exclamation mark as part of the icon. This does not mean that it is a mistake or that it is dangerous, only to inform you that it contains macros. "Feature" or insufficiently thought out placement of punctuation? This is completely normal, and everything is fine as long as you trust the document and / or create the document and macros yourself.
