Decimal to Text

Convert decimal numbers back into characters, treating them as Unicode code points or as raw UTF-8 bytes, with clear errors for surrogates and out-of-range values.

How to use the Decimal to Text

  1. Paste the decimal numbers, separated by spaces or commas.
  2. Choose whether they are Unicode code points or raw UTF-8 byte values.
  3. Click "Convert to text".

Frequently asked questions

Which unit should I choose?

If the numbers came from HTML entities, a Unicode reference table or the Text to Decimal tool in its default mode, choose code points. If they came from a byte-level dump, a network capture or a file reader, choose bytes.

Why are some numbers rejected as surrogates?

The range 55296 to 57343 is reserved for UTF-16 encoding machinery and never represents a character on its own. A lone surrogate in your data means the text was split incorrectly somewhere upstream.

  • Previous step: Text to Decimal — Convert text into decimal numbers – full Unicode code points by default, so an emoji becomes a single number such as 128512 rather than several byte fragments.
  • Next step: Text to Octal — Convert text into octal, base 8, at three digits per byte.
  • ASCII to Text — Turn ASCII character codes back into text, with an option to name control characters such as LF and TAB instead of printing invisible bytes.
  • Unicode Code Point Converter — Look up the code point of every character – with its decimal value, UTF-8 bytes and UTF-16 units – or turn U+ notation back into text.
