Telerik Spreadsheet format providers displaying a exception i.e. "The name you have entered is not valid" while reading .xlsx file in Silverlight appl

Which name said I did not understand ?

Hi,

The error message refers to the Defined Names feature of RadSpreadsheet and, most likely, the file you are trying to import contains a name which is invalid. If you try to open the same file in Excel, I expect that you will get a message that the file is corrupted and that Excel can try to fix it. If you choose to attempt fixing it, it will most likely do it by deleting the name in question.

I hope this helps.

Hi,

In this case, we'll need to see the document in order to determine what precisely is going on. This is possible by opening a support ticket or by uploading the file using a service of your choice.
