ASCII Table

How to use it

1. Scroll the table or type in the Filter box to narrow it down.
2. The filter matches all four columns at once: decimal value, hex value, the character itself, or its name (try tab, esc, 2C or a single character).
3. Each row shows the decimal value, two-digit hexadecimal, the character and a human-readable name.
4. Click any row to copy that character to your clipboard — including control characters like tab or newline.
5. Leave the filter empty to see all 128 entries again.

Common use cases

• Checking escape codes — confirm that 09 is tab and 0D is carriage return before writing a parser.
• Reading hex dumps — keep the table open next to a hex editor output and decode bytes by their two-digit hex value.
• Writing char classes — look up exact ranges like 0x30-0x39 for digits when building regexes.
• Naming characters in docs — copy the canonical name instead of guessing what ^ or ~ is called.

Why it stays private

The table is embedded in the page and the filter runs in local JavaScript. No request is made when you search or copy, so the page also works fully offline.

FAQ

Q: Why do control characters show a dot in the Char column? A: Codes 0-31 and 127 have no visible glyph. They still copy correctly — for example, clicking the TAB row puts a real tab character on your clipboard.

Q: Does it cover extended ASCII (128-255)? A: No. Codes 128-255 were never standardized as one table; they depend on the codepage (Latin-1, CP437 and so on). This tool sticks to the unambiguous 0-127 range.

Q: Can I search by hexadecimal value? A: Yes. Type one or two hex digits, with or without a 0x prefix intent in mind — the filter matches the two-digit hex column, so 1b finds ESC in both hex and name matches.
