列表左侧补齐（补零、补空格右对齐）Left-Pad a List
把列表每一项在左侧补上字符，使所有项目长度相同：默认补到最长项目的长度，也可以指定宽度；补空格得到右对齐效果，补 0 得到 001、002 这样的固定位数编号（负号保持在最前面，如 -05），也可以用任意字符补齐；可按显示宽度计算中文（每个汉字算 2）。适合对齐数字、生成固定长度编号和排版文本，数据在本地处理。Pad every item in a list on the left so they all have the same length. By default items are padded to the longest one, or you can set the width. Pad with spaces to right-align, with zeros for fixed-width numbers like 001 and 002 (a minus sign stays in front, as in -05), or with any character. Width can be measured by display width, counting each Chinese character as two. Handy for aligning numbers, fixed-length IDs and text layout. Processed locally.

删除列表中连续重复的项目，像 Unix 的 uniq 命令：相邻的相同项目只保留一个（不相邻的重复会保留，保持原有的分段和顺序），也可以只保留没有连续重复的项目，或在每项前显示连续出现的次数；可忽略大小写和首尾空格。适合清理日志、去掉重复粘贴的行和压缩传感器数据，数据在本地处理。Delete items that repeat consecutively in a list, like the Unix uniq command. Runs of identical neighbouring items are collapsed to one, while repeats that aren't next to each other are kept, so the order and grouping stay intact. You can also keep only items that never repeat consecutively, or show how many times each run occurred. Case and surrounding spaces can be ignored. Handy for cleaning up logs, removing accidentally repeated lines and condensing sensor data. Processed locally.

If every item is a number you also get the sum, mean, median, minimum, maximum, range and standard deviation. Separators such as new lines and commas are detected automatically, and case can be ignored. Handy for checking name lists, data columns and survey results quickly. Processed locally.

Accents are removed (é → e, ñ → n), ligatures are split (æ → ae, ß → ss, fi → fi), full-width letters, digits and punctuation become half-width, curly quotes, long dashes, ellipses and special spaces become ordinary symbols, and © ™ € and similar turn into (c) (TM) EUR.

Styles include ASCII (+-|), Unicode lines, rounded, double, Markdown and compact, with an optional header row, row separators, and left, centre, right or automatic alignment (numbers to the right). Chinese, Japanese and full-width characters count as double width, so columns stay aligned in a monospaced font. Great for code comments, READMEs, terminal output and chat. Processed locally.
随机大小写转换（随机 / 交替大小写）Randomize ASCII Case
把英文字母随机转换成大写或小写，制造 “sPoNgEbOb” 式的混合大小写效果：可设置大写的概率和随机种子（相同种子得到相同结果），也可以按字母交替（aBcD）、按字符位置交替或按单词交替大小写。只改变字母，数字、标点和中文保持不变。适合做表情包文字、测试大小写不敏感的程序和生成示例数据，数据在本地处理。Randomly turn letters into upper or lower case for that mixed "sPoNgEbOb" look. Set the chance of upper case and a random seed (the same seed gives the same result), or alternate the case letter by letter (aBcD), by character position or word by word. Only letters change; digits, punctuation and Chinese stay as they are. Handy for meme text, testing case-insensitive programs and making sample data. Processed locally.
