ASCII Table
Searchable ASCII table with decimal, hex and character for all 128 codes.
ASCII is the 128-character foundation every text encoding builds on, and its code points surface constantly: a newline is 10, a space is 32, the digit "0" is 48, uppercase "A" is 65. Whenever you're debugging a parser, reading a hex dump, or working out why a control character snuck into a file, the ASCII table is the reference you reach for.
This is the complete table — all 128 codes with their decimal value, hexadecimal value, character, and a description for the non-printable control characters (NUL, tab, CR, LF, ESC and the rest). Search by number, hex, or character to jump straight to what you need.

Frequently asked questions
Common mistakes to avoid
- Assuming byte values above 127 are ASCII — those belong to extended encodings or UTF-8 multi-byte sequences.
- Confusing the character "5" (code 53) with the numeric value 5 when parsing text.
