Hi and Greetings! And apologies if my previous mail sounded rude. That was 
surely not my intent.

Here is an example. The NA in column a shows up in the results as nil. Why does 
that happen? Is there a way of changing this behaviour? I can manually replace 
NA with something else, but doing that in each code block is a pain. Since I 
wrote my first mail, I have written an export filter that filters out each 
“nil” at the time of export and replaces it with a “---“. But that is not 
perhaps the most efficient way of doing it.

Warmly,

Vikas
