set the export file name and extension of excel

[Kevin]

I have followed a lot of the things online but my export filename seems to work but not the extension of the excel file.  It always ends up being aspx and it gives me the trusted file error.  I think I am getting this because it does not like the aspx extension.

Hello Kevin,

I suppose you have set some Unknown extension and that is why the exported page is opening with  aspx extension.
Please check out the following forum for more on this.
