<![CDATA[Glump.net]]> Commentics Robbie MS blocked the opening of these types of files in a recent automatic update, but have gone back on this block and are in the process of rolling out a fix (as part of the usual automatic update) next week.

http://stackoverflow.com/questions/38466169/response-contenttype-application-vnd-ms-excel-xls-stopped-working

The issue is related to Microsoft Security Update KB3115262 for Excel that was released July 12, 2016. The security update information can be found in Microsoft Security Bulletin MS16-088 - Critical.

I've found three workarounds (in my order of preference):

Instead of clicking Open, save the file and then open it
In Excel Trust Center > Trust Center Settings > Protected View, uncheck the top two options. This is potentially unsafe.
Uninstall the security update.

MS patch to fix this issue: support.microsoft.com/en-us/kb/3181507 – S McCrohan 8 hours ago

I did notice one trick is to save the file first then open it, insted of just using open in IE.

An easy workaround is to click on save and open at the bottom of the page and it will display the warning message about the file format which you reply yes to as usual and it should open like before. This will of course leave files in the temp directory or wherever you save the file to, so it is not the best fix.

]]> Mon, 08 Aug 2016 16:25:34 -0400 item_28 Brendan Kidwell I'm aware that there are some problems, but I haven't been paying attention to it or to this method of getting data into Excel.

]]> Mon, 08 Aug 2016 13:30:55 -0400 item_27 Sandra We've been successfully doing this: generating htm file and writing it to excel as .xls and it has worked fine.
Now some machines don't handle it and a blank file comes up. Do you know if there is some sort of setting or security that is prohibiting this now?

]]> Mon, 08 Aug 2016 13:19:39 -0400 item_26 daniel Well.... If I need to generate a html file to excell with around 200 Mb??? At the moment my Ms Excel stop working and not open the archive, this will resolve my issue?

It's not working in in Safari. Pls suggest if there is any way to get this done.

Thanks,
Sathiya

I've no problem generating files like these, except when opened, numbers appear as text (i.e. aligned to the left, no digit grouping, etc.). When I click in the cell and then press Enter, it picks up the format I've assigned to it in the html file.
As such, my question is whether you'd know how to display cells holding numbers as regular numbers and not as text... ?

Thanks,
D
