Add new line characters (\n) into CSV file?

Question

I have a CSV files whose data is taken from multiple other CSV files. I copied over the data from these files one column at a time and I want the file to be read one line at a time using the c++ method getLine().

Problem is that getLine returns the entire file as one line. I suspect the way I copied them and did not include a column with an end line character has lead to each row not having the character at the end.

Is there a way to add them in? I'm using Libre Office but I can also switch to excel.

Open it in Libre Office's word processor. Save it as whatever file type Libre saves documents. That should add the proper line endings. Then save it back as plain text.
