IDECLSIDConv Add-In convert string or search GUID/IID from uuid.lib.
For example: IID_IDispatch returns formatted string:
const CLSID IID_IDispatch = {0x00020400,0x0000,0x0000,0xC0,0x00,0x00,0x00,0x00,0x00,0x00,0x46};
IID_IDispatch GUID <000020400H,00000H,00000H,<0C0H,000H,000H,000H,000H,000H,000H,046H>>
