Data Cleaning Workbench

An "OpenRefine Lite": load a messy CSV, stack up an ordered recipe of cleaning steps β€” trim, casing, find & replace, split/merge, dedupe, date & number normalization β€” and watch the live before/after preview. Export the cleaned CSV, a plain-English change log, or the recipe itself to reuse on another file. Everything runs in your browser.
