Cells No longer works with IE 10. Google Chrome and Firefox are fine

Our site will download XLS, PPT, and Word fine in Chrome or FF but IE 10 it won't.

How can we fix this? We haven't changed anything. Our users are upgrading their browsers which we have no control over.


I have tested your scenario with our latest fix/version: Aspose.Cells for .NET v7.5.1.x, it works absolutely fine in IE10 browser too.

I created a sample web application /project and write the following code snippet in Page_Load event:

Sample code:

protected void Page_Load(object sender, EventArgs e)
if (!Page.IsPostBack)
Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];
worksheet.Cells[“A1”].PutValue(“Hello World!”);

workbook.Save(this.Response, “testin1.xlsx”, ContentDisposition.Attachment, new OoxmlSaveOptions(SaveFormat.Xlsx));


I can open or save the generated XLSX file without any problem in IE10 browser type. Make sure you have not put any restrictions to open download dialog box etc. in IE 10, so your files could be opened or saved properly.

Thank you.
