Excel Password Types Explained: Which Ones Can Be Removed?
Updated March 2026 · 6 min read
Microsoft Excel has multiple types of password protection, and they vary dramatically in strength. Some can be removed in seconds; others use military-grade encryption. Understanding the difference saves you time and frustration.
Removable Protections (Weak)
These protections use simple XML flags or weak hashes. They can be removed without the password.
1. Sheet Protection (Protect Sheet)
Set via Review → Protect Sheet. Prevents editing cells, formatting, and structure on individual worksheets. Stored as a <sheetProtection> XML tag with an optional SHA-512 hash.
Can be removed? Yes — the tag can simply be deleted.Remove it free with XL Unlocker.
2. Workbook Structure Protection
Set via Review → Protect Workbook. Prevents adding, deleting, renaming, or reordering sheets. Stored as a <workbookProtection> tag.
Can be removed? Yes — same XML-deletion technique. XL Unlocker handles this.
3. Read-Only Recommended
Set during Save As → Tools → General Options. Prompts users to open read-only. Stored as a <fileSharing> tag.
Can be removed? Yes. Learn more in why is my Excel file read-only.
4. Write Protection (Modify Password)
Set during Save As. Requires a password to save changes. Stored as a <writeProtection> tag.
Can be removed? Yes — XL Unlocker removes this automatically.

5. File-Open Password (Encryption)
Set via File → Info → Protect Workbook → Encrypt with Password. This encrypts the entire file with AES-256 encryption. The .xlsx archive itself is encrypted and cannot be read without the correct password.
Can be removed? No. AES-256 is computationally infeasible to crack. No legitimate tool can remove this. If you've forgotten this password, recovery is essentially impossible.
6. VBA Project Protection
Protects macro code (VBA) from being viewed. Stored in the vbaProject.bin binary stream. While technically breakable with specialized tools, XL Unlocker does not modify this to avoid corrupting macros.

How to Tell Which Protection You Have
- Can you open the file? If Excel asks for a password before opening, it's file-open encryption (not removable).
- Can you open but not edit? Likely sheet protection, write protection, or read-only recommendation — all removable with XL Unlocker.
- Can you edit cells but not add/delete sheets? Workbook structure protection — removable.
Not sure which protection your file has? Just upload it to XL Unlocker — the tool automatically detects and reports which protections were found and removed. See our step-by-step removal guide for more details.
