nice, what id I have missing lines or columns in the data. What is the syntax to shift to next element/key if one is missing while still separating by every new line?

IE:
12x3.12z34b.342sd3.sds 454.23.23.232 aSDGgsOds

4z3x3.134b.332sSSsd3.Ccsds 354.23.2113.232
12x333.123ww4b.342sed3.sdsO 22454.23.23.20032 BSDGgds

For the missing line, you will need to check whether the line is empty in the loop and skip over. This is an easy exercise. Try to find out yourself first.

Missing column sometimes cannot be checked. It depends on how irregular your data set can be.
