Power Query Update for translation application

I recently watched a youtube video from mr excel and was able to use your code to translate a robotics program into English with little to no prior use of the software. I was wonder if there was a way to update the code to eliminate the need to have an error for blank columns or special spaces such as an asterisk or a question. I feel this query was already useful for my translations but could be used for future use in my industry by professionals. I feel this is something a person in my field would be willing to pay for and if you make a dollar on in it hey I appreciate your hard work and you should hook me up with the query for free. I appreciate your hard work as my robotic project was a nightmare trying to copy and paste thousands of lines of code with googles translate limit of 5 thousand characters. Thanks again for your hard work.
