How to use Draw an ASCII Table
- 1. Choose the Range. Select 7-bit (0 to 127) for the standard ASCII set or 8-bit (0 to 255) to include the extended character range as well.
- 2. Read the reference table. The tool lists every code point in the chosen range alongside its decimal, hexadecimal, octal and printable character values in one table.
- 3. Copy the reference table. Copy the finished table and keep it handy or paste it into documentation whenever you need to look up a character's code.
When to use Draw an ASCII Table
Draw an ASCII Table generates a full reference chart of character codes and their printable characters, covering either the standard 7-bit ASCII range or the extended 8-bit range. It replaces flipping between a printed chart or a search engine every time you need to check what code a character maps to.
- Looking up a control character's code. You need to know the exact decimal or hex value of a control character like a tab, newline or escape character while writing a parser. Generating the 7-bit table here gives you every code in one place.
- Referencing extended characters for legacy hardware. You're working with a device or file format that uses the extended 8-bit range for box drawing or accented characters. Generating the 8-bit table shows what each of those codes actually is.
- Building a cheat sheet for a systems course. A networking or systems programming class covers ASCII codes and you want a printable reference for exams or homework. Generating the table here gives a complete, accurate chart in seconds.
- Cross checking a custom character map. You're implementing a custom encoding or font and want to verify it against the standard ASCII assignments. Generating the reference table lets you compare code by code.
