However, sometimes, a hex editor is also used to edit text files. With this editor, you can see invisible characters such as the start of the file, line break, end of the file, and other special characters.

This tool displays the data as a matrix, each cell corresponding to one byte, written in hexadecimal notation as a two-digit number. Corresponding ASCII data can be displayed to the right of the matrix. ​​Usually, the file offset area is to the left of the matrix, which shows the current character offset in bytes at the start of the string, forming the start of the file.
