How to remove the carriage return from string while pasting content to Excel file

Question

I have a problem while pasting my contents (or text) generated by Java code into excel. The problem is that my Java code generates a String with multiple lines, i.e. with li

Answer 1

Try this =)

String s1 = "this\r\nis a test";
String s2 = s1.replaceAll("(\\r|\\n)", "");
System.out.println(s2);

Answer 2

If it is any help, I ran this line of code (C#)

Clipboard.SetText("1\n2\r\n3");

and then Ctrl-V in Excel and 3 cells got filled with A1 got 1, A2 got 2 and A3 got 3. This means that \n and \r\n are handled as expected by Excel. Java strings containing \n and \r\n should work as well. This leads me to believe something's up with the Excel cell settings. Check if the cells are formatted as text.

Other than that, no idea, sorry.

Answer 3

Why don't you copy and paste as usual, then do a search and replace at Excel?

Answer 4

Do you want the carriage return / newline, or don't you? Your title says that you don't, your code is explicitly adding carriage returns when the string has a newline. If you want to get rid of both, use String.replaceAll(), which takes a regex:

public static void main(String[] argv)
throws Exception
{
    String s1 = "this\r\nis a test";
    String s2 = s1.replaceAll("[\n\r]", "");
    System.out.println(s2);
} 

This example finds any occurrence of the characters, and deletes them. You probably want to look for the sequence of characters and replace with a space, but I'll leave that up to you: look at the doc for java.util.regex.Pattern.

And I suspect that the "box" is some other character, not a return or newline.

Answer 5

class Test {
    public static void main(String args[])
    System.out.print("Hello\rHi");
}

Due to \r cursor moves to starting of the current line, so "He" of Hello is replaced by "Hi".
