Route
/xlsx/decrypt
Canonical noun-first path on cryptvert.com.
Why teams protect Excel workbooks
People search for this route when they want to encrypt XLSX files online without moving the workbook through a cloud office upload step.
When Cryptvert is better than native protection
Native workbook passwords are tied to office software. Cryptvert is better when you want a browser-based handoff that wraps the whole spreadsheet before it moves outside your control.
Best for
- Forecasts, budgets, and pricing sheets sent to clients or partners
- Operational workbooks shared over email or ticketing systems
- Spreadsheet archives that need a password stored separately from the file
Not for
- Formula auditing or workbook editing inside the encrypted package
- Native Excel permission management for collaborative teams
- Sheet-level protection or cell-locking workflows
Common use cases
- Vault financial models before sharing them with leadership
- Protect inventory sheets during vendor handoffs
- Encrypt workbook exports before storing them in shared folders
Mistakes to avoid
- Assuming the route edits workbook permissions instead of wrapping the file
- Using the wrong route for CSV-only exports
- Forgetting that .xls files are accepted alongside .xlsx
Quick checklist
- Confirm the workbook is an .xls or .xlsx file
- Use a unique passphrase for the vault
- Download the .vault output before closing the tab
- Keep the password separate from the workbook delivery path

Visible FAQ
What does the XLSX decrypt route actually do?
Cryptvert decrypts a .vault package that originally contained a Excel workbook and restores that file locally on your device.
Can this page encrypt both XLS and XLSX files?
Yes. This route accepts both legacy XLS and modern XLSX spreadsheet files.
Does Cryptvert change formulas, tabs, or formatting?
No. The original workbook is wrapped as-is, so formulas, tabs, and formatting stay with the source file.
What comes back after decryption?
You get the original Excel workbook back, ready to open in the same spreadsheet tools you used before encryption.
