Text To Ascii
Text To Ascii — runs in your browser. Inputs are not stored.
Text → character codes
Shows each character’s Unicode code point. ASCII range (0–127) is included.
How to use
- Put the string to analyze in Text. One line or many, each character gets one result line.
- In Display format, choose decimal, hexadecimal (
0xprefix), or both. - Press Convert to build a
character → codelist. - Space is shown as
(space), newline as\n, and tab as\tso invisible characters are distinct. - Reset clears input and result and restores format to decimal. Nothing is sent to a server.
- It is especially useful for spotting mixed invisible spaces and tabs. The label changes to
(space). Choose format before converting.
Key concepts
Even though the name says ASCII, actual output is Unicode code points. English letters, digits, and basic symbols are 0–127 like an old ASCII table; Hangul and emoji are larger numbers. Hex mode prefixes 0x, as in 0x48 or 0xAC00. Use it for programming homework, encoding bugs, and a table of “what number is this character.” Pairing character and code on one line makes typos easier to spot.
If a text-to-decimal tool lists numbers only, this one pairs each glyph with its code on one line. Newlines, tabs, and spaces get escape labels so control characters mixed in during copy are easier to find. Supplementary-plane emoji are counted as one code point, not two surrogates. Input is processed only in the browser. Switching display format to view the same sentence in decimal and hex makes it easier to match an assignment answer.
Example
Hi in decimal is two lines: H → 72, i → 105. Both mode is H → 72 / 0x48. 가 is 가 → 44032 or 0xAC00. A trailing space leaves a last line (space) → 32 so you see the cause at once. Multi-line text inserts a \n row at each line break so you can count paragraph boundaries.

Frequently asked questions
Are an ASCII code table and Unicode code points different?
English letters, digits, and basic symbols at 127 and below are the same. Hangul, emoji, and special symbols are not on an ASCII table and are shown as Unicode numbers.
Does Hangul appear when converting text to ASCII codes?
Yes. Despite the tool name, it lists the whole Unicode range one character at a time. Hangul syllables are numbers in the 44032 range.
What format is the character-code hex?
<code>0x</code> and uppercase hex. If you need <code>U+AC00</code> notation, use code-point mode in the Unicode converter.
How do space and newline look?
Space is labeled <code>(space)</code>, newline <code>\n</code>, tab <code>\t</code>. Useful for finding invisible characters mixed in during copy.
Is emoji ASCII code also one line?
One code point is one line. Skin-tone or ZWJ sequences can add a line per component character.
Does ASCII conversion remain on a server?
No. The list is built only in the browser according to the display format you chose and is not stored.
