After deployement Error while loanding the Excel File

Hi All,

We are facing the error after deployment, we cannot able to load Excel file into the Gridweb.

Type : ‡.?, Aspose.Cells.GridWeb, Version=, Culture=neutral,
Message : This file’s format is not supported
or you don’t specify a correct format.
Source :


TargetSite : Void
ƒ?(System.String, ?.Ž)
Stack Trace : at •..ƒ?(String , Ž )
Aspose.Cells.GridWeb.Data.WebWorksheets.ImportExcelFile(String fileName)


Kindly provide the solution at the earliest.



Please make sure that you are loading a valid/native Excel file (e.g XLS, XLSX etc.).

If you still sure that it is a valid Excel file, kindly attach the Excel file here. We will check it soon.

Thank you.


Thanks for your quick response. We are being used the excel extension like (xlsx and xlsm).
At the time of development it’s working fine but when it deploy on a website the above error is coming.

Is there we are missing some where related to configuration ? please suggest.



Yes, I think it might be deployment problem or configuration problem, please make sure that you have deployed the latest version of the product (Aspose.Cells.GridWeb v2.7.14.xxxx) with the solution and the you have specified the details (if there is any in the web.config file) fine regarding acw_client (path) etc.

If you still could not evaluate, please create a separate project (runnable), zip it and post it here to show the issue on our end. So, that we could check your issue soon.

Thank you.
