The Text to ASCII Converter turns any text into its numeric ASCII code values. Type a word and instantly see the number behind each character — 'A' as 65, 'a' as 97 — a clear, practical view of how computers identify the characters you type.
What ASCII Codes Are
Every character has a number assigned by the ASCII standard. This converter reveals those numbers directly: instead of binary, it gives you the readable decimal codes — 'H' is 72, the space is 32, '!' is 33. These values are the bridge between human-readable text and the way software actually compares, sorts, and processes characters.
How to Convert
- Type your text.
- Convert to get each character's ASCII code.
- Copy the codes for your use.
Common ASCII Codes
| Character | ASCII | Character | ASCII |
|---|---|---|---|
| A | 65 | a | 97 |
| Z | 90 | z | 122 |
| 0 | 48 | (space) | 32 |
The Clever 32 Offset
Look closely at the table and a pattern jumps out: each lowercase letter's code is exactly 32 more than its uppercase counterpart ('A' 65, 'a' 97). This isn't a coincidence — ASCII was designed that way so software can switch a letter's case simply by adding or subtracting 32. It's one of the most elegant tricks in character encoding, and seeing the codes makes it obvious.
Why Programmers Care About ASCII Codes
Beneath the surface, a lot of programming is ASCII arithmetic. Sorting strings, comparing characters, validating that input is a digit or letter, and converting case all operate on these numeric codes. When string-handling code misbehaves, viewing the raw ASCII values is often the fastest way to spot what's really happening — an unexpected space, a capital where you expected lowercase, or a hidden character.
Text to ASCII vs. Text to Binary
The difference is simply the notation. This tool gives the decimal codes (65), which are compact and easy to use in code; a text-to-binary converter writes those same codes in binary (01000001). Choose ASCII codes when you want readable numbers, binary when you need the raw bits.

Frequently Asked Questions
What does text to ASCII produce?
It returns the numeric ASCII code for each character in your text. The word 'Hi', for example, becomes 72 105 — the codes for 'H' and 'i'. These are decimal numbers from the ASCII table.
What's the difference from text-to-binary?
Text-to-ASCII gives the decimal code numbers (like 65 for 'A'), while text-to-binary gives those same codes written in binary (01000001). This tool stops at the numeric values, which are easier to read and use in code.
What are some common ASCII codes?
Capital 'A' is 65, lowercase 'a' is 97, '0' is 48, and the space is 32. Capital letters run 65–90 and lowercase 97–122, each set in alphabetical order, which makes many programming tricks possible.
Why is the gap between 'A' and 'a' exactly 32?
Uppercase and lowercase letters are offset by 32 in ASCII, so you can switch case by adding or subtracting 32 from a letter's code. This deliberate design simplifies case conversion in software.
Are ASCII codes used in programming?
Yes, constantly. Comparing characters, sorting, validating input, and converting case all rely on their ASCII values. Seeing the codes directly helps when debugging string handling.
Does it handle symbols and punctuation?
Yes. Every standard character has an ASCII code, including punctuation and the space, so they all convert to their numeric values.
Is my text private?
Yes. Conversion runs in your browser and nothing is uploaded or stored.
Is this tool free?
Yes — free, instant, and unlimited, with no signup.
