Text to ASCII Converter

The text-to-ASCII calculator converts each character in an ASCII string into its decimal character value. For example, uppercase A becomes 65, lowercase a becomes 97 and a space becomes 32. Results remain in character order and are separated by spaces.

ASCII is a 7-bit character set with values 0 through 127. This page now rejects characters outside that range rather than showing the individual bytes of their UTF-8 encoding. Accented letters, emoji and most non-English scripts belong to Unicode and need a Unicode code-point or encoding tool instead.

1. Enter up to 1,000 ASCII characters in the text area. Standard spaces, tabs, and line breaks are included as characters.
2. Select Convert to ASCII.
3. Read one decimal value for each character in the same order. Values are separated by spaces.
4. Remember that spaces and punctuation have their own values. For example, a line feed is 10.

Only values in standard 7-bit ASCII (0 through 127) are accepted. Accented letters and emoji are rejected rather than being split into UTF-8 bytes. The converter does not parse numeric codes: typing “65” converts the characters 6 and 5.

The output lists each character’s decimal ASCII code in order. It is useful for learning character mappings or checking a short text sequence, but it does not encrypt or hash the text and can be reversed easily.

ASCII includes control characters as well as printable characters. A line feed is 10, a tab is 9, and carriage return is 13. The text area allows line breaks, but line-ending conventions differ between systems; inspect file bytes directly when exact CR/LF behavior matters.

This page reports decimal values only. Decimal 65, hexadecimal 41, and binary 1000001 all identify A. Unicode characters outside ASCII, including accented letters and emoji, require a Unicode-aware converter.
