    Getting error when trying to save excel with UseOOXMLFormat flag, please see code below:

    Code : -
    string fileName = "test" + DateTime.Now.ToString("yyyyMMddhhmmss") + ".xls";

    Spread.SaveExcel(fileName, FarPoint.Excel.ExcelSaveFlags.UseOOXMLFormat);

    I am not sure what error are you getting on saving Spread to Excel but you could be facing some error like "File is potentially dangerous to open.. etc..".

    If yes, then this is a file validation thing that Microsoft added to Office 2010 that for some reason treats the exported spreadsheet as "potentially dangerous" but doesn't give any reason why.

    If this isn't the error you are getting then please share your error and Spread ASP.Net version as well, we will look into this issue thereon.
