What is ASCII to Text Converter?

An ASCII code list is simply text written as decimal byte values. Each number from 0 to 255 is one byte; the bytes are then decoded as UTF-8, which means codes 0–127 give plain ASCII characters and multi-byte sequences such as 195 169 give "é".

The converter accepts spaces, commas, semicolons, new lines and even array brackets like [72, 105]. It reports the exact token when something is not a whole number or is above 255, so a typo is easy to find.

How does it work?

  1. Paste your codes, separated by spaces, commas or new lines.
  2. Keep UTF-8, or choose ISO-8859-1 if your codes come from a Latin-1 table (for example 233 = é).
  3. Read the text below, or use Swap to convert text back to codes.

Common use cases

  • Decoding a charCodeAt() dump or a byte array printed by your program.
  • Solving puzzles that hide a message as ASCII numbers.
  • Turning the numbers in a serial-monitor log into readable messages.
  • Verifying a homework answer on the ASCII table.

Examples

Try this input in the tool above:

Input
72 101 108 108 111 44 32 87 111 114 108 100 33
Output
Hello, World!

Privacy

ASCII to Text Converter runs entirely in your browser. The text or files you provide are processed on your device and are not uploaded, logged or stored on our servers.

Limitations

Codes are treated as bytes (0–255). For Unicode code points above 255 (such as 8364 for €), use Decimal to Text.

Frequently asked questions

Why does 8364 give an error?

ASCII/byte codes stop at 255. 8364 is the Unicode code point of €; convert it with Decimal to Text, or supply its UTF-8 bytes 226 130 172.

Which separators work?

Spaces, commas, semicolons, tabs and line breaks, with or without surrounding brackets or braces.

What happens with codes below 32?

They are control characters (tab, line feed…). They are kept in the output, so you may see line breaks or invisible characters.
