- 1). Download and install jEdit (see link in Resources). Unfortunately, even though newlines are indicated within a file by characters just like any other, text editors such as Notepad and WordPad, which come with Windows, do not support Find and Replace operations with them. jEdit is a special type of text editor known as a programming text editor. This means that, in addition to ordinary text editing abilities, it has features of special interest to programmers, such as support for invisible characters in Find and Replace.
- 2). Open your text file in jEdit. Upon opening your file, you should recognize the interface of jEdit as being very similar to that of any other text editor.
- 3). Click "Search and Find." Alternatively, you can press either Alt-F or Command-F, depending on your operating system.
- 4). Turn on regular expressions. Having the checkbox next to regular expressions checked turns on a variety of special codes we can enter into the search box to produce special results.
- 5). Type \n into the "Search For" box. Since newline characters are normally hidden during text editing, you need to enter a special code to let the computer know what you want. Programmers will recognize "\n" as the code used for newlines in many programming languages.
- 6). Leave the "Replace With" box empty. Since you want to remove newlines, not replace them with some other text, leave this box empty.
- 7). Click "Replace All." All the text in the file will be compressed onto one line.
- 8). Save the file and open it with your preferred editor.
