How to use the ASCII table

Scroll the table, or type in Search by code, character or name. A decimal code (65), hex (0x41), octal (\101), binary (01000001), one character (A) or a word such as tab, newline or tilde all work, and so do control keys like Ctrl+C.
Read across a row: Dec, Hex, Oct, Bin, the character, its HTML entity and its Name. Control codes show an abbreviation such as LF, with the escape sequence and Ctrl key underneath.
Press Show 128 to 255 (Windows-1252) to add the extended codes. They are not part of ASCII.

How the ASCII table works

ASCII (American Standard Code for Information Interchange) is a 7-bit code with 128 values: 33 control codes (0 to 31 and 127) and 95 printable characters (32 to 126, including the space). It is described in RFC 20, and the first 128 Unicode code points are identical, so every ASCII file is also valid UTF-8.

The digits 0 to 9 are codes 48 to 57, so a digit's value is its code minus 48. A letter and its other case differ by exactly 32 (one bit): A is 65 and a is 97. A control code is its Ctrl key with the top bits cleared: Ctrl+J is 0x4A AND 0x1F = 0x0A, the line feed.

Worked example

With the search box empty, the status line begins "Showing all 128 ASCII codes." and the table lists every code from 0 to 127. Row 65 shows Dec 65, Hex 41, Oct 101, Bin 01000001, Char A, HTML A and Name Uppercase A. Check it by hand: 65 = 64 + 1, which is 0100 0001 in binary, 0x41 in hex and 101 in octal. Type 65 and the table narrows to that row.

Limits and edge cases

ASCII has no accented letters, euro sign or emoji. Codes 128 to 255 belong to 8-bit code pages, and the extended rows here use Windows-1252, which differs from ISO-8859-1 in 128 to 159. Codes 129, 141, 143, 144 and 157 are undefined in it.
UTF-8 keeps 0 to 127 as single bytes but writes é as two bytes (C3 A9), so a Windows-1252 file read as UTF-8 shows errors.
The HTML column lists only references that are valid in HTML, so most control codes say none.
Single-character searches are case-sensitive, so A and a find different rows. Every other search ignores case.

To convert whole strings instead of single codes, use the binary text converter, the number base converter or the HTML entity encoder.

Frequently asked questions

What is the ASCII code for space, tab and newline?

Space is 32 (hex 20), tab is 9, line feed (the newline on Linux and macOS) is 10 and carriage return is 13. Windows text files end each line with 13 followed by 10.

How many characters are in ASCII?

ASCII has 128 codes: 95 printable characters (32 to 126, including the space) and 33 control codes (0 to 31 and 127). "Extended ASCII" with 256 characters is not one standard but a family of 8-bit code pages.

What is the difference between ASCII and Unicode?

ASCII covers 128 characters, enough for unaccented English. Unicode covers over 150,000 characters from every script, and its first 128 code points match ASCII, so plain ASCII text is already valid UTF-8.

Why are uppercase and lowercase letters 32 apart?

A is 65 (01000001) and a is 97 (01100001), so they differ only in the bit worth 32. Flipping that one bit changes the case, and it is why sorting by ASCII code puts uppercase before lowercase.
