String to Decimal Converter
Enter text and receive one exact decimal Unicode code point per character. The conversion runs locally.
A QUICK WALKTHROUGH
How to use this tool
- Enter text up to 131,072 characters.
- Click Convert.
- Read or copy the space-separated decimal code points.
Unicode code points
The output uses Unicode scalar values, not UTF-16 surrogate units. A supplementary character such as 😀 is one code point (128512). Input containing an unpaired surrogate is rejected.
Defined limits
Up to 131,072 UTF-16 input characters and 32,768 Unicode code points are accepted. Output is space-separated decimal digits and is capped at 294,912 characters.
Local processing
Conversion and manual copying happen in this browser tab. No input is uploaded or stored.
GOOD TO KNOW
Common questions
Does each visible character always produce one number?
Each Unicode code point produces one number. A displayed grapheme such as a family emoji may contain several code points.
Are emoji supported?
Yes. Valid surrogate pairs are combined into their Unicode code point; unpaired surrogates are rejected.
Can the result be used by the decimal-to-string converter?
Yes for values in its ASCII range. This tool can output larger Unicode code points that an ASCII-only decoder cannot read.
