If you are using a windows based operating system, Notepad and Wordpad are the two programs that can be used to open the TXT files. However, if you're using a macOS computer, TextEdit comes attached to it and is a good choice for both creating and as well as editing the TXT files. When you want to edit a PDF without any formatting and want to convert it into a plain text beyond the basic styling, this tool is the best option for you. This tool can convert all kinds of pdf files into text files which provide information about the texts. As a result, you can edit the text and modify accordingly to suit your best use.
