I have downloaded latest Excel Utility and created JSON file. But, error while uploading file "Error : The uploaded JSON file which was created via offline utility has invalid data format. Please make sure JSON file is not tampered and you are using the correct offline utility..". I have tried to upload through 4 different browsers IE, Crome, Mozilla & Opera but, still unable to upload. Even changing the file name from JSON to JSO also didn't helped . Please help me to solve this error. Getting this error since last 4 days,
Is everyone getting this error?
