Looking up character codes one at a time across decimal, hex and octal is slow and error-prone.
ASCII Table Generator builds a code table over the range you choose, with no text to paste.
How to use ASCII Table Generator
- Set the decimal start, end and step values; no pasted text is required.
- ASCII Table Generator lists each code with its decimal, hex and octal value and character.
- Copy the generated table, or download it as a .txt file.
Use cases
- Building a reference table of printable ASCII codes.
- Listing control-code names for a given range.
- Generating a decimal, hex and octal lookup for characters.
Good to know
ASCII Table Generator produces rows for the decimal range you set, showing each code in decimal, hexadecimal and octal alongside its character. Control codes below 32 and 127 are shown by their standard names such as NUL, TAB and DEL.
Frequently asked questions
What range can I generate?
You set a decimal start, end and step, and the table covers every code in that range at the chosen interval.
How are control codes shown?
Codes that have no printable glyph, such as those below 32 and 127, are labelled with their standard names like TAB and DEL.
Does it require any pasted text?
No. The table is built entirely from the start, end and step controls; there is no text input.
