  • Hi abualsaeed,

    There is a security feature in Excel, introduced with Office 2007, that matches the content of the file and the file name extension.   

    That warning will show up when the security feature is enabled and it detects possible incompatibility between the actual content of the file and the file name extension, which can cause unexpected problems.   

    For more details, please review this support KB:https://support.microsoft.com/en-us/kb/948615

    Best regards,

    Kristin
