What is Text to ASCII?

Every character has a numeric ASCII code but memorizing them all is impossible. You need a fast lookup whenever you debug or teach encoding.

Paste any text and get the ASCII code for every character.

If you're debugging string handling, you spot encoding issues fast. If you're teaching computing basics, you show the number behind every letter. If you're working with low-level code, you check exact decimal values.

How to use Text to ASCII

Four steps. No setup, no signup.

  1. Step 1

    Paste your text

  2. Step 2

    See ASCII codes per character

  3. Step 3

    Compare letters to their numbers

  4. Step 4

    Hit Copy and use the codes

Example

Each character mapped to its decimal ASCII code.

Input

Hi!

Output

H = 72
i = 105
! = 33

Why Text to ASCII is useful

  • ✓

    Spot encoding bugs by checking exact decimal values.

  • ✓

    Teach the number behind every letter (A=65, a=97, space=32).

  • ✓

    Verify low-level string handling at a glance.

  • ✓

    Stack with Text to Binary for the full encoding view.

Common questions

What is ASCII?

American Standard Code for Information Interchange. 128 characters numbered 0-127.

Tip: 'A'=65, 'a'=97, space=32.

What about Unicode characters?

Standard ASCII covers 0-127. Extended ASCII goes to 255. Unicode beyond uses different codes.

Tip: Stick to English text for pure ASCII.

Decimal vs hex output?

This tool shows decimal. Use a hex converter for 0x41 style output.

Tip: Hex is common in low-level code; decimal in education.

What's the difference between A and a?

Capital A is 65, lowercase a is 97. The 6th bit differs.

Tip: Bit-flip the 6th bit to toggle case in code.
