hi @aydinaghali thanks for your PR :)
can you please apply camel case style to your variables?
new_line --> newLine

@aydinaghali one last thing:
CSV does not always use line breaks to indicate a new row. In some cases, CSV readers use a fixed number of columns to split the dataset, so escaping is not required.

Escaping new lines in strings should be optional (like the seperator field) and (maybe?) disabled by default.

Could you also enrich the README?
Thank you so much for your work.
