Text files often consist of characters defined in the ASCII (American Standard Code for Information Interchange) set. The standard ASCII set has 128 characters, and includes letters of the English alphabet as well as symbols such as exclamation marks and commas. However, some texts may also contain non-ASCII symbols. The ANSI (American National Standards Institute) encodes an extended set of symbols to allow a text file to be properly displayed. A default editor in Windows, Notepad, allows you to convert text into the ANSI format.
Click on the Windows "Start" button in the lower left corner of the screen.
Click on "All Programs" and open the "Accessories" folder.
Click "Notepad" to start the editor.
Find the text file you need to convert to ANSI by browsing your computer.
Double-click on the file to open it in Notepad.
Click the menu "File" and then "Save As" to open the "Save As" window.
Select "ANSI" in the drop-down box labeled "Encoding."
Type a desired file name in the field and click "Save" to convert the text file into the ANSI format.
