About ASCII Codes → Text
This tool reverses text-to-ASCII: each numeric token is interpreted as a Unicode code point, and the sequence is assembled into a string. Values up to U+10FFFF are supported (including emoji and other astral-plane characters).
When to use it
- Decoding decimal-encoded puzzles
- Recovering text from a char-code dump
- Verifying a text-to-ASCII round-trip
- Manually constructing a string with specific characters
How it works
The input is split on whitespace or commas. Each token is parsed as a decimal integer; non-numeric tokens surface an error. The resulting code points are joined via String.fromCodePoint.
Examples
72 101 108 108 111

Frequently asked questions
- Are values capped at 127?
- No. Although called 'ASCII', the tool accepts any Unicode code point up to 0x10FFFF. Strict ASCII inputs (≤ 127) produce ASCII characters; higher values produce non-ASCII Unicode.
- Are commas allowed as separators?
- Yes. Whitespace and commas can both separate tokens.
