Sometimes I just need to search and replace to add the CR/LF at the end of each line. Here's the solution I find from other's post. List here for quick reference: Notepad++. Open your text file in Notepad++. Then navigate to menu View > Show Symbols > Show all characters. Highlight one of those squares in your text, then copy it to clipboard. Press Ctrl+H. Inside "Find what:" textbox, paste (Ctrl+V). Inside "Replace with:", type \r\n In search options, choose "Extended (\r, \n, \t, \0, \x...)"....
