Reverse TextReverse characters, words or lines of any text.Word CounterCount words, characters, sentences and paragraphs live.Character CounterCount characters with and without spaces, including byte length.Line CounterCount lines, empty lines and longest line of pasted text.Remove Duplicate LinesDelete repeated lines while keeping order.Sort LinesSort lines alphabetically, numerically, by length, ascending or descending.Shuffle LinesRandomize the order of lines using a cryptographic RNG.Trim WhitespaceRemove leading/trailing spaces and tabs from every line.Add Prefix & Suffix to LinesWrap every line with a custom prefix and suffix.Line NumberingAdd or remove line numbers on any text block.Merge LinesJoin all lines with a custom separator.Find & Replace in TextSearch and replace text with plain or regular-expression matching.Palindrome CheckerCheck if text or numbers read the same backwards.Text Diff CheckerCompare two texts line by line and highlight additions and deletions.Lorem Ipsum GeneratorGenerate placeholder paragraphs, sentences or words.Zero Pad NumbersPad numbers with leading zeros to a fixed width.String RepeaterRepeat any string or character a given number of times.Whitespace CleanerCollapse spaces, strip blank lines and normalize line endings.Slug GeneratorTurn titles into clean, SEO-friendly URL slugs.Zero-Width Character RemoverDetect and strip invisible characters and bidi controls used in Trojan Source attacks.Text Pattern ExtractorPull every email, URL, IP, MAC, UUID, hashtag, mention, date or hash out of unstructured text.Levenshtein DistanceEdit distance and similarity between two strings, with Damerau and Hamming variants.Character Frequency AnalyzerCount characters, words, line lengths or n-grams and compute Shannon entropy.Word Frequency CounterRank words by frequency with the type/token ratio — useful for keyword density checks.Line Ending ConverterConvert between LF, CRLF, CR, NEL and LS, and report the mix currently in the file.Add line numbersAdds line numbers to the output.Alternating CapsAlternating caps, also known as studly caps, sticky caps, or spongecase is a form of text notation in which the capitalization of letters varies by some pattern, or arbitrarily. An example of this would be spelling 'alternative caps' as 'aLConvert to NATO alphabetConverts characters to their representation in the NATO phonetic alphabet.Expand alphabet rangeExpand an alphabet range string into a list of the characters in that range. e.g. a-z becomes abcdefghijklmnopqrstuvwxyz .From Case Insensitive RegexConverts a case-insensitive regex string to a case sensitive regex string (no guarantee on it being the proper original casing) in case the i flag wasn't available at the time but now is, or you need it to be case-sensitive again. e.g. [mM]From Quoted PrintableConverts QP-encoded text back to standard text. This format is a content transfer encoding common in email messages. e.g. The quoted-printable encoded string hello=20world becomes hello worldGenerate Lorem IpsumGenerate varying length lorem ipsum placeholder text.Get All CasingsOutputs all possible casing variations of a string.Index of CoincidenceIndex of Coincidence (IC) is the probability of two randomly selected characters being the same. This can be used to determine whether text is readable or random, with English text having an IC of around 0.066. IC can therefore be a sound mLZString CompressCompress the input with lz-string.MurmurHash3Generates a MurmurHash v3 for a string input and an optional seed inputROT13 Brute ForceTry all meaningful amounts for ROT13. Optionally you can enter your known plaintext (crib) to filter the result.

This is often used when dealing with malicious links or IOCs. Works well when coEscape Smart CharactersConverts smart (typographic) Unicode characters — e.g. smart quotes, em/en dashes, ellipses, ©, ®, ™, arrows — into their plain ASCII equivalents. Characters with no ASCII mapping (e.g. ☣ ) are handled according to the 'Unmappable characterEscape Unicode CharactersConverts characters to their unicode-escaped notations. Supports the prefixes: \u %u U+ e.g. σου becomes \u03C3\u03BF\u03C5From Base62Base62 is a notation for encoding arbitrary byte data using a restricted set of symbols that can be conveniently used by humans and processed by computers. The high number base results in shorter strings than with the decimal or hexadecimalNormalise UnicodeTransform Unicode characters to one of the Normalisation FormsParse ASN.1 hex stringAbstract Syntax Notation One (ASN.1) is a standard and notation that describes rules and structures for representing, encoding, transmitting, and decoding data in telecommunications and computer networking. This operation parses arbitrary AStringsExtracts all strings from the input.To Base92Base92 is a notation for encoding arbitrary byte data using a restricted set of symbols that can be conveniently used by humans and processed by computers.To PunycodePunycode is a way to represent Unicode with the limited character subset of ASCII supported by the Domain Name System. e.g. münchen encodes to mnchen-3yaUnescape stringUnescapes characters in a string that have been escaped. For example, Don\'t stop me now becomes Don't stop me now . Supports the following escape sequences: \n (Line feed/newline) \r (Carriage return) \t (Horizontal tab) \b (Backspace) \f VarInt DecodeDecodes a VarInt encoded integer. VarInt is an efficient way of encoding variable length integers and is commonly used with Protobuf.
