JavaScript —在字符串的每个换行符处插入“ \\ r \\ n”

Question

I'm trying to use this CSV parsing library to parse my CSV, but it seems that this library needs "\\r\\n\\" to be at the end of every row.

Right now, my CSV looks like this:

Bob, Smith, Cats,
Annie, Johnson, Dogs

How do I add the string "\\r\\n\\" right after "Cats" and "Dogs"? Or is this unnecessary? Thanks!

Answer 1

Check what works for your environment!

You could change the default '\\r\\n' to '\\n' like below:

var csv = new CSV(data, { line: '\n' });

Hope this helps!

Answer 2

You may try something like this:

var text = "Box, Smith, Cats\nAnnie, Johnson, Dogs";
text = text.split( "\n" ).join( "\r\n" );

Answer 3

In this case, the documentation indeed says you can simply specify the line characters yourself with the line option as already pointed out in the other answer.

Just providing some additional info on this:

\\r stands for carriage return
\\n stands for line feed (newline)
Depending on which program you used to generate or manually write the CSV file, when you hit Enter this will produce either \\n or \\r\\n

You can 'pre-cure' this with a text editor like Notepad++, Sublime Text, Brackets, etc. which have a regex replace feature. ( Ctrl + H to bring it up in most cases). Most notably, Notepad++ allows you to see all characters in the View menu (\\r will show up as a block with CR & \\n will show up as a block with LN).

Simply check the Regex checkbox or icon and replace all \\n with \\r\\n or vice versa.
