About the Text to ASCII Converter
This tool converts text into its numeric character codes and converts a list of codes back into text. Type a word to see the code for each character, or paste space-separated numbers to reconstruct the message they represent.
What ASCII and character codes are
Every character a computer handles is stored as a number. ASCII, the American Standard Code for Information Interchange, was the original widely adopted scheme, assigning numbers 0 to 127 to letters, digits, punctuation, and control signals. The capital letter A is 65, a lowercase a is 97, and the digit 0 is 48. Modern systems extend this with Unicode to cover every writing system on Earth, but the underlying idea is unchanged: text is numbers, and these codes are the bridge between the characters you read and the values a computer stores.
How the conversion works
To encode, the tool reads each character and outputs its numeric code point, separated by spaces. To decode, it reads each number and produces the character that code represents. For ordinary English text these are the classic ASCII values; for accented or non-Latin characters the codes are the larger Unicode code points, since those characters live beyond the original ASCII range.
Why this is useful
Seeing the codes behind text helps in several situations. Programmers debugging text-processing code often need to know the exact code of a character, especially to spot invisible or unexpected characters that look like spaces but are not. Students learning how computers represent text use this to make the abstract concrete. It is also a simple way to understand why, for example, sorting text puts uppercase before lowercase: their codes determine the order.
Spotting hidden characters
One practical use is diagnosing mysterious bugs caused by characters that look normal but are not, such as a non-breaking space instead of a regular space, or a curly quote where a straight one was expected. Converting suspect text to codes reveals these impostors immediately, because their numbers differ from the ordinary characters they resemble.
Privacy and related tools
Conversion happens entirely in your browser, so your text is never transmitted. For converting text to Morse code see the Morse Code Converter, and for Base64 encoding the Base64 Encoder / Decoder. Both directions of conversion are instant.
Frequently Asked Questions
How do I convert text to ASCII code?
Type or paste your text and it is converted to the ASCII (character code) numbers for each character. Paste numbers instead and it decodes them back to text.
What is the ASCII code for A?
Uppercase A is 65 and lowercase a is 97; digits 0-9 are 48-57. The converter gives the code for any character you enter.
How do I convert ASCII codes back to text?
Paste the space-separated numbers — for example 72 73 for “HI” — and the tool turns them back into readable characters.
What is ASCII?
ASCII (American Standard Code for Information Interchange) assigns a number to each letter, digit and symbol so computers can store and exchange text. The tool also handles Unicode code points beyond classic ASCII.
Is the text to ASCII converter free and private?
Yes — it is free, needs no sign-up, and converts entirely in your browser with nothing uploaded.
