Secure Excel - Protection for Zapier

PDF4me Secure Excel gives you enterprise-grade protection for sensitive spreadsheets with multi-level password controls. Secure files with encryption so only authorized users can open them, lock workbook structure to prevent sheet additions or deletions, or protect individual worksheet cells to allow viewing but block editing. Use different passwords for each protection level, or one master password—giving you complete control over who sees and edits your data. Perfect for financial reports, customer data, confidential analytics, or templates that shouldn't be modified accidentally.
