How to use Convert Decimal to UTF8
- 1. Paste the decimal numbers. Enter one or more base-10 numbers, such as 65, separated by spaces. Each number is treated as either a byte value or a code point depending on the sequence you paste.
- 2. Read the decoded characters. The tool interprets the decimal values and reconstructs the UTF8 characters they encode, turning plain numbers back into readable letters and symbols.
- 3. Copy the text. Copy the resulting characters from the output pane once the numbers have become text, ready to paste into your document or code.
When to use Convert Decimal to UTF8
Convert Decimal to UTF8 turns plain base-10 numbers into the characters they represent. Decimal is the most common way byte values and code points get printed in logs, debuggers and documentation, since it needs no special notation like 0x or U+. This tool reads those numbers and shows you the text.
- Reading a decimal byte array from a log statement. An application logs a string as a plain array of decimal numbers, like from a Java byte array's toString. Converting that list here reveals what the original string actually said.
- Checking a character code from a quick script. You ran charCodeAt in a browser console and got back a decimal number. Pasting it here confirms which character that code actually represents.
- Verifying numbers copied from a Unicode reference table. A reference table lists code points in decimal rather than the more common hex U+ notation. Converting the decimal value here shows the character without doing the hex conversion in your head.
