Frequently asked questions
What counts as whitespace?▾
Any character matched by JavaScript's \s regex: space, tab, newline, carriage return, form feed, vertical tab, plus various Unicode whitespace like non-breaking space.
Does 'collapse' affect leading whitespace?▾
Yes — collapse mode replaces all whitespace runs with a single space and trims leading/trailing whitespace from the whole string.
Can I replace with a multi-char string?▾
Yes — the 'replace with' field takes any string, including emoji or multiple characters.
