Way to take values from datasheet and output

[Ankur]

I am not sure what is your 'Use Case' but here is what can be done -

1. Count the total no of active rows in your data sheet.
   
2. Divide it by 17 to get the (total no of groups -1)
   
3. Mod it by 17 to get remaining no of rows.
   
4. Store 2) and 3) above in an array as you wish.
