Quick answer
To convert text to ASCII, replace every character with its ASCII code number. Hello becomes 72 101 108 108 111: H = 72, e = 101, l = 108 and o = 111. Spaces and punctuation have codes too, so "Hi!" becomes 72 105 33.
Our free text to ASCII converter encodes a whole word, sentence or paragraph in one click. Choose space-separated, comma-separated or fixed 3-digit output, then copy the codes. A character map below the result shows each letter's decimal, hex and 8-bit binary value, which makes it a good learning aid as well as a quick utility.
How Text to ASCII Encoding Works
Computers store text as numbers. The ASCII standard assigns a number from 0 to 127 to every English letter, digit, punctuation mark and a few control characters. When you convert text to ASCII, the tool reads each character in order and outputs its number. Uppercase and lowercase letters have different codes: A is 65 while a is 97, exactly 32 apart.
How to Use the Text to ASCII Converter
Step 1: Type or Paste Your Text
Keep Text to ASCII selected and enter your text in the box. We type Hello.
Step 2: Choose the Output Delimiter
Pick Space, Comma or Continuous Block (3-digit fixed). Space is easiest to read; comma is handy for code arrays; 3-digit blocks give a single string like 065098099. We use spaces.
Step 3: Click Convert Payload
Press Convert Payload to run the text to ASCII conversion.
Step 4: Copy the ASCII Codes
The output reads 72 101 108 108 111. Click Copy Result to copy it. The Character Matrix Map lists each character with its decimal index, hex code and binary stream.
Text to ASCII Examples
| Text | ASCII codes (space) |
|---|---|
| Hello | 72 101 108 108 111 |
| Hi! | 72 105 33 |
| ABC | 65 66 67 |
| abc | 97 98 99 |
| 123 | 49 50 51 |
| A b | 65 32 98 |
| VectraTools | 86 101 99 116 114 97 84 111 111 108 115 |
Notice that the digits 1, 2 and 3 are not stored as 1, 2 and 3. Their ASCII codes are 49, 50 and 51.
Which Output Format Should You Use?
| Format | Example for "Abc" | Best for |
|---|---|---|
| Space | 65 98 99 | Reading, homework, puzzles |
| Comma | 65, 98, 99 | Arrays in code, CSV data |
| 3-digit block | 065098099 | Fixed-width storage, ciphers |
Uses of Text to ASCII Conversion
- Learning to code: understanding how strings become numbers, and functions like ord() in Python or charCodeAt() in JavaScript.
- Debugging: finding hidden characters such as non-breaking spaces or stray line breaks.
- Puzzles and games: writing secret messages for escape rooms or CTF challenges.
- Embedded systems: preparing byte values for microcontrollers and serial protocols.
Common Mistakes to Avoid
- Forgetting spaces are characters. A space becomes 32 in a text to ASCII result.
- Expecting the same code for upper and lower case. They always differ by 32.
- Using non-English characters. Letters like é or emoji are outside basic ASCII and need Unicode.
- Confusing decimal with hex. The output is decimal; the map shows hex separately.

Frequently Asked Questions
How do I convert text to ASCII?
Replace each character with its ASCII number. "Hi" becomes 72 105.
What is the ASCII code for a space?
A space is ASCII 32.
What is the ASCII code for the letter A?
Capital A is 65 and lowercase a is 97.
Can I get comma-separated output?
Yes. Choose the Comma option in the delimiter menu before converting.
Does it show hex and binary too?
Yes. The character map lists the hex code and 8-bit binary for every character.
Is this text to ASCII converter free?
Yes. It is free, needs no sign-up, and runs entirely in your browser.
