I have a malformed CSV file with many lines similar to:

a;b;c;d;e;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;^M

I am struggling to find the right regular expression to use in my Vi editor to eliminate the multiple contiguous semicolons (there are many more on each row) and the DOS ^M and obtain just the clean data such as

a;b;c;d;e;

CodePudding user response：

First, you need to remove the trailing semi-colons with

:%s/;\ $//g

Then, run this to convert line breaks to LF:

::set ff=unix

And save the file:

:w
