✂️ 分割与合并Split & Merge
按行、按字符数、按分隔符或正则表达式把文本拆分成多段；也可以把多段文本按分隔符合并成一段。结果每行一段，并显示段数。Split text by lines, character count, delimiter or regex; or merge multiple blocks with a separator. One block per line, with a block count.
① 输入文本① Input
合并模式下，输入框的每一段（以空行分隔）会被合并。In merge mode, each block (separated by a blank line) in the input is joined.
② 模式与参数② Mode & options
③ 结果③ Result

全程在你的浏览器本地完成，文本不会上传服务器。Runs entirely in your browser; your text is never uploaded.
「合并」模式：在输入框用空行把多段文本隔开，再设置合并分隔符即可拼成一段。其余模式为拆分，结果每段占一行。Merge mode: separate blocks in the input with blank lines, then set a join separator. Other modes split; each block becomes one line.
