Getting Started
Simply enter your list into the input area using your preferred delimiter. Then, select the appropriate action from the toolbar to see your list transformed instantly. The results will appear in the output area for you to review or copy.
Custom & Regex Delimiters
Choose Other in the input separator to type any custom delimiter. Tick Use Regex to treat it as a regular expression – for example \s+ splits on any run of whitespace, or \d+ on any run of digits.
One thing to know: a capturinggroup keeps the matched separator as its own item, because that is how JavaScript’s split works. For instance (,) on a,b,c yields a, ,, b, ,, c. If you only want to split and not keep the separator, use a non-capturing group – (?:,) – or drop the parentheses entirely. (Whitespace separators are trimmed away automatically, so a group like (\s+) is safe.)
