Text to ASCII Codes Converter

About this tool

Convert text into its ASCII / Unicode decimal code points, one number per character.

Example

Input: Hi!

Output: 72 105 33

How to use

Paste or type your text into the box above, then read or copy the result. Everything runs privately in your browser, your text is never uploaded to a server.

How to use this tool

1. Type or paste the text you want to inspect into the input box.
2. Check the decimal code point output shown by the tool for each character.
3. Copy the numbers if you need them for testing, debugging, or documentation.
4. Edit the text and watch the output update instantly.

Step by step, what happens

1. The tool reads your text one character at a time, including spaces and punctuation.
2. Each character is converted to its ASCII or Unicode decimal code point.
3. The tool displays one decimal number per character, in the same order as the input.
4. If the input contains letters outside basic ASCII, the tool still shows their Unicode decimal values.

Worked example

If you enter a short label like OK, the tool shows the decimal code point for each character.

Input: OK

1. The tool takes the first character, O, and converts it to its decimal code point.
2. It then converts the second character, K, and keeps the same left to right order in the output.

Tips and common mistakes

• Spaces are characters too, so they produce their own decimal values in the output.
• Uppercase and lowercase letters do not share the same code points, so test the exact casing you need.
• If you paste accented letters or symbols, expect Unicode decimal values, not only classic ASCII numbers.
• Use a short test string first if you want to confirm how the tool handles punctuation or whitespace.
