I have a file like this:
aaa b b ccc 345 ddd fgt f u 3456 e r der der 5 674
As you can see the only way that we can separate the columns is by finding columns that have only one or more spaces. How can we identify these columns and replace them with a unique separator like
aaa,b b,ccc,345 ddd,fgt,f u,3456 e r,der,der,5 674
If we find all continuous columns with one or more white spaces (nothing else) and replace them with
, (all the column) the problem will be solved.
Better explanation of the question by
josifoski : Per block of matrix characters, if all are 'space' then all block should be replaced vertically with one , on every line.
