❓ FAQ
How do I convert text to ASCII codes?+
Each character in your text is looked up by its position in the ASCII table — its "code point". For example, "A" is ASCII 65, "a" is 97, "0" is 48. This tool converts every character automatically.
What is the ASCII code for common characters?+
Key ASCII codes: Space=32, 0–9=48–57, A–Z=65–90, a–z=97–122, newline=10, tab=9. "Hello" = 72 101 108 108 111.
What is octal notation?+
Octal is base-8 (digits 0–7). It was historically used in computing before hex became dominant. ASCII 65 (A) = octal 101, ASCII 97 (a) = octal 141. The conversion table shows all four bases for each character.
Can I get ASCII codes for emoji?+
Emoji are not in ASCII — they have Unicode code points above 127. This tool uses charCodeAt() which returns the UTF-16 code unit. For emoji this will be a number above 127 (or a surrogate pair for characters above U+FFFF).
What is the format for C/Python character arrays?+
For C, format codes as comma-separated with values like {72, 101, 108}. For Python, format as comma-separated decimals or use [chr(n) for n in [72,101,108]]. The comma + space separator in this tool produces C/Python-compatible output.
