Due which file saving in All file format

the reason it wasn't working was, you should have name your document with extension like following
mhndev\slimFileResponse\FileResponse::getResponse($response, $filePath ,'myDocument.xlsx');

but now I fixed it, now if you type your filename to be myDoc it checks origin file extension and concatenate it with the extension just update your project composer
