Unlock Excel - Remove Protection for Zapier

PDF4me Unlock Excel removes password protection from Excel files automatically, handling the complexity of multi-layer protection with intelligent password fallback. Whether files are encrypted to prevent opening, have workbook structure protection, or contain worksheet-level cell locks, this action systematically removes each protection layer—automatically trying different passwords in logical order if multiple passwords are provided. Perfect for batch processing archived files, editing previously protected templates, or preparing documents for distribution without access restrictions.
