The simplest file format for unformatted text is plain text or flat file format. This format contains no structural elements and no markups and can be opened by any text program or text editor. The file extension is *.txt. Corresponding files consist of ASCII characters or Unicode and are often used as a basic format for word processing.
Text formats are computer-readable file formats whose texts can be captured by text recognition, converted from speech to text by text-to-speech or speech-to-text, and processed using word processing.
