Bulk Clean CSV & Excel Files Online

Bulk clean CSV and Excel files online without uploading them anywhere. Choose 2 to 20 spreadsheets at once and SheetSweep runs the same cleaner on each file, one after another, inside your browser.

Each file gets the same treatment as the single-file cleaner: duplicate and blank rows removed, stray spaces trimmed, and dates, emails, phone numbers, names, and statuses standardized. A file that cannot be cleaned is skipped and marked, so the rest of the batch still finishes.

Download one ZIP containing every cleaned file, a byte-identical copy of each original, and a combined change log. Bulk cleaning is a Pro feature; choosing a single file uses the free cleaner.
