Convert text to decimal ASCII codes (Unicode code points for other characters) and codes back to text.
Also covers: Text to ASCII · ASCII to text
The result appears here as you type.
Text → codes gives the decimal code of each character (H = 72). Codes → text turns numbers back into characters.
Space, comma, or one code per line. Decoding accepts any mix of separators.
Characters beyond ASCII get their full Unicode code point, so 😀 is 128512, not a broken pair of numbers.
ASCII only covers codes 0–127. For everything else, like é, €, or emoji, the tool uses the character's Unicode code point, which matches ASCII for the first 128 characters. The summary tells you when that happened.
1114111 (hex 10FFFF), the last Unicode code point. The range 55296–57343 is reserved for UTF-16 surrogates and isn't valid on its own; both cases are reported as errors.

Text & code
Compare two texts or code files side by side, with changed words highlighted. Ignore whitespace or case, and export a unified .diff patch that git apply accepts.
Count
Count words, characters, sentences, paragraphs, and lines as you type, with reading and speaking time. Check text against X, SEO title, and meta description limits.
Case
Convert text to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and more, line by line.
Cleanup
Clean up messy text: remove extra spaces, blank lines, invisible characters, and HTML tags, straighten quotes, and rejoin hard-wrapped lines.
Lines
Delete repeated lines from a list and keep the original order. Choose case sensitivity, whether to ignore surrounding spaces, and whether to keep the first or last copy.
Lines
Delete blank lines from text, or collapse runs of blank lines down to one so paragraphs stay separated.
