In the “Cleaning & formulas” card, steps apply in order to every row; the original data is not changed.
Free: trim spaces, turn text into numbers, parse dates, remove duplicates.
Pro: prices with currency, row filters, text replace (including patterns), split and merge columns, computed columns with formulas like {Price} * 1.2 — column names go in braces.
Formulas are Grabsavo's safe expression language, not code: only arithmetic, comparisons and a few functions.
