I have a string containing both "CRLF" and "LF" as line separator.

I want to replace only "CRLF" with " LF" (space and LF) and keeping "LF" as it is.

I know,we can do this using regex, but I have tried few regex from the already existing answers, but not able to resolve.

Please help, I am new to the javascript/jQuery.

• You should post your regexp. Basically -> CR => \r LF => \n Then : var regexp_clean_CRLF = new RegExp("\r\n", "g"); my_string = my_string.replace(regexp_clean_CRLF, " \n") – Waxo Commented Jun 18, 2015 at 6:55

As simple as

the_string.replace(/\r\n/g, "\n");

where \r is the escape sequence for CR and \n is the one for LF and g is a regex modifier to replace all matching instances instead of only the first one found.
