Complete ASCII table: the definitive guide
Decimal and hexadecimal codes with characters and controls (ASCII 0–127).

The ASCII table is the foundation of text encoding in computing. It defines 128 codes (0–127) for printable characters and control codes. This guide shows the full table with decimal and hexadecimal values.

What is ASCII?

ASCII (American Standard Code for Information Interchange) maps numbers to characters. It includes letters, digits, punctuation and control codes.

Complete ASCII table (0–127)

The table below highlights control codes (0–31 and 127) and printable characters (32–126). Use the “Bin” column to compare bits.

Examples: 65, 0x41, A, LF, TAB, Euro

Extended ASCII (128–255)

“Extended ASCII” is not a single standard. It depends on the encoding(for example, Windows-1252 or ISO-8859-1). That means the 128–255 table varies by system and language. For modern applications, prefer Unicode/UTF-8.

How to use the ASCII table

  • Convert characters to codes in scripts and automation.
  • Interpret bytes in logs and legacy protocols.
  • Validate input by ASCII ranges.

Quick FAQ

Is ASCII the same as Unicode?

No. ASCII covers only 128 symbols. Unicode is much larger and includes most writing systems.

Why do some characters not show?

Codes 0–31 are control characters (line feed, tab, etc.), not printable symbols.

Conclusion

ASCII is still useful for understanding legacy systems and simple protocols. For modern applications, pair it with Unicode/UTF-8 knowledge.
