The thing is, you're NOT exporting the grid to an Excel file. You're sending an HTML document to the browser, but "lying" in the headers and telling it the response is an Excel document. Excel is then doing its best to convert the HTML into an Excel worksheet.

Not only does this limit your control over the formatting and prevent you from using any "advanced" features of Excel, it also leaves you subject to the whims of whatever version of Excel the user has installed. When you run into strange problems like this, there is often no obvious cause or workaround.

If you're lucky, you might be able to track it down to a recent security update, or a change to the users' settings. But telling your users to uninstall security updates just to get your code working again isn't a sensible option.

You'll probably have better luck if you change your code to create a real Excel file. Since you're using ASP.NET, you can't use Office Interop[^]. But there are several open-source libraries which are safe to use from server-side code:
