逆順テキストReverse characters, words or lines of any text.単語カウントCount words, characters, sentences and paragraphs live.文字カウントCount characters with and without spaces, including byte length.行カウントCount lines, empty lines and longest line of pasted text.削除重複行Delete repeated lines while keeping order.並べ替え行Sort lines alphabetically, numerically, by length, ascending or descending.シャッフル行Randomize the order of lines using a cryptographic RNG.空白除去空白文字Remove leading/trailing spaces and tabs from every line.AddPrefix&Suffixto 行Wrap every line with a custom prefix and suffix.行番号付けAdd or remove line numbers on any text block.結合行Join all lines with a custom separator.検索&置換 in テキストSearch and replace text with plain or regular-expression matching.Palindrome チェックCheck if text or numbers read the same backwards.テキスト差分チェックCompare two texts line by line and highlight additions and deletions.ダミー文 Ipsum 生成Generate placeholder paragraphs, sentences or words.ZeroPad 数値Pad numbers with leading zeros to a fixed width.文字列繰り返しRepeat any string or character a given number of times.空白文字クリーンアップCollapse spaces, strip blank lines and normalize line endings.スラッグ生成Turn titles into clean, SEO-friendly URL slugs.Zero-Width 文字 RemoverDetect and strip invisible characters and bidi controls used in Trojan Source attacks.テキストパターン抽出Pull every email, URL, IP, MAC, UUID, hashtag, mention, date or hash out of unstructured text.Levenshtein 距離Edit distance and similarity between two strings, with Damerau and Hamming variants.文字頻度分析Count characters, words, line lengths or n-grams and compute Shannon entropy.単語頻度カウントRank words by frequency with the type/token ratio — useful for keyword density checks.行改行変換Convert between LF, CRLF, CR, NEL and LS, and report the mix currently in the file.AddlinenumbersAdds line numbers to the output.AlternatingCapsAlternating 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 'aLConverttoNATOalphabetConverts characters to their representation in the NATO phonetic alphabet.ExpandalphabetrangeExpand an alphabet range string into a list of the characters in that range. e.g. a-z becomes abcdefghijklmnopqrstuvwxyz .From 大文字小文字 Insensitive 正規表現Converts 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]FromQuotedPrintableConverts 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 ダミー文 IpsumGenerate varying length lorem ipsum placeholder text.GetAllCasingsOutputs all possible casing variations of a string.IndexofCoincidenceIndex 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 mLZStringCompressCompress the input with lz-string.MurmurHash3Generates a MurmurHash v3 for a string input and an optional seed inputROT13BruteForceTry all meaningful amounts for ROT13. Optionally you can enter your known plaintext (crib) to filter the result.削除 DiacriticsReplaces accented characters with their latin character equivalent. Accented characters are made up of Unicode combining characters, so unicode text formatting such as strikethroughs and underlines will also be removed.削除 linenumbersRemoves line numbers from the output if they can be trivially detected.削除 whitespaceOptionally removes all spaces, carriage returns, line feeds, tabs and form feeds from the input data. This operation also supports the removal of full stops which are sometimes used to represent non-printable bytes in ASCII output.SplitSplits a string into sections around a given delimiter.

This is often used when dealing with malicious links or IOCs. Works well when coEscapeSmartCharactersConverts 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 characterEscapeUnicodeCharactersConverts characters to their unicode-escaped notations.

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 VarIntDecodeDecodes a VarInt encoded integer. VarInt is an efficient way of encoding variable length integers and is commonly used with Protobuf.
