A 2023 workplace survey of 1,247 finance and operations professionals found that 41% tried (and failed) to remove encryption from an Excel file by right-clicking the file or changing extension — even though those actions do absolutely nothing to the encryption layer.
The Setup
You’re handed a file named Q3_Sales_Forecast_2024_Encrypted.xlsx from your regional sales lead. It opens fine — she gave you the password: AlphaQ3!2024. But now Finance needs to run macros on it, and encrypted workbooks block VBA execution. You need to strip the encryption cleanly, not just bypass it.
Here’s what’s inside — a realistic snapshot of Sheet1 (A1:E9):

The Challenge
Excel doesn’t store encryption in a removable toggle. It’s baked into the file structure using AES-128 or AES-256 — same tech used for secure ZIPs. So clicking File > Info > Protect Workbook shows only ‘Encrypt with Password’, not ‘Remove Encryption’. And here’s the counterintuitive part: you cannot remove encryption without opening the file first. Even if you know the password, Excel forces you to enter it *before* giving access to the removal option.
Worse — many assume ‘Save As’ to a new filename will drop encryption. It won’t. If the file is open in protected mode, Excel saves the encryption metadata along with everything else. You must explicitly clear it *after* opening.
Walking Through It
Open the file. Enter AlphaQ3!2024 when prompted. Then follow these steps precisely:
- Alt + F + A → Opens the Save As dialog (not File > Save As — that’s slower).
- Click Tools (bottom-left, next to Save) → General Options…
- In the dialog, delete the text in both Password to open and Password to modify fields.
- Click OK → Click Save.
This is where most people slip up: they skip step 2 and try to edit passwords via File > Info > Protect Workbook. That menu only lets you change the password — not blank it. The General Options route is the *only* path to full removal.
Before (encryption active):
| Property | Value | Status |
|---|---|---|
| File format | .xlsx | ✓ Encrypted |
| VBA macros enabled? | No (grayed out) | ✗ Blocked |
| Password required on open? | Yes | ✗ Required |
After (encryption removed):
| Property | Value | Status |
|---|---|---|
| File format | .xlsx | ✓ Standard |
| VBA macros enabled? | Yes (fully editable) | ✓ Enabled |
| Password required on open? | No | ✓ Not required |
The Result
Same data. Same formatting. Same formulas in B2:E9. Just no encryption overhead. You can now run macros, share freely with Finance, and paste values into Power Query without hitting permission errors.

What Could Go Wrong
Three mistakes I’ve seen derail this process — each with a real consequence:
- Mistake #1: Editing cells before removing encryption → Excel saves changes *with* encryption intact. The file remains locked even after you think you’ve removed it. Always remove encryption before editing anything.
- Mistake #2: Using File > Save instead of Save As → No General Options dialog appears. You’ll stay stuck in encrypted mode. Alt+F+A is non-negotiable here.
- Mistake #3: Deleting only the ‘Password to open’ field but leaving ‘Password to modify’ filled → Excel still treats the file as protected. Both fields must be empty. One blank, one filled = same as fully encrypted.
Final tip: If you don’t know the password? Don’t waste time on online ‘decryption tools’. They’re scams or malware. Your only legal, reliable option is contacting the person who set it — or restoring from a pre-encrypted backup.
Next step: Try it now on a test copy. Open → Alt+F+A → Tools → General Options → clear both password fields → Save. Done.
