Unprotect Excel worksheets with XiaoMiBao online decryption

While organizing company documents, Xiao Li, the owner of the file

, discovered that an Excel worksheet had been set with an open password. He tried to open it but couldn't, which put him in a dilemma.

When encountering this type of problem, the first thing to do is determine whether you need to unlock the open password or remove worksheet protection. If the file is only protected, you can restore normal use by removing protection permissions; If the file is set with an open password, it needs to be unlocked before any operation can be performed.

1. Revoke worksheet protection permissions

For worksheets that only have protection permissions set, you can directly use the online tool to remove these restrictions.

1. Log in to the website homepage and enter the Remove Protection Permissions page.
2. Upload the Excel file that needs to be unlocked and click "Start Processing". The system will process it automatically in the background and will take approximately 5 minutes.

• Do not upload large files larger than 50MB, otherwise the upload may fail.
• Ensure that the uploaded file path is correct.
• Do not close the browser page during the operation to avoid upload interruptions.
• Download the processing result file promptly after decryption to avoid data loss.

II. Unlock the password

For worksheets that are set to open with a password, Xiao Li needs to use stricter methods to unlock them. We recommend using the Xiaomibao online decryption tool here.

1. Log in to the website homepage and enter the Excel password recovery page.
2. Follow the prompts to upload the Excel file and enter the correct open password. Please note that you entered an open password instead of a worksheet protection password.
3. After submission, the system will process it automatically, without waiting for customer service to confirm. The general processing time is about 10 to 30 minutes.

• Ensure that the password entered is completely correct; Incorrect passwords can cause processing to fail or unlock.
• Do not disclose or share your file open password with others to prevent information leakage.
• Before uploading files, make sure your antivirus software or firewall is turned off to avoid affecting upload speed and success rate.
• If the file contains macro code, ensure that the macro code is not set to be password protected; Otherwise, it may affect the decryption process.

III. Batch Processing and Precautions

If Xiao Li needs to process multiple Excel files in batches, he can use the manual batch import feature. The specific steps are as follows:

1. Find the Bulk Import option on the Excel Password Recovery page and register an account (registration is free).
2. Follow the prompts to add multiple Excel files and enter their respective open passwords.

• When processing in batches, please ensure that the upload path of each file is correct and not duplicated; Otherwise, some files may not be processed correctly or the upload may fail.
• During the batch import process, please wait patiently for the system to process it automatically. Do not frequently refresh the page to cause confusion in the processing state.
• Ensure that the server is running stably before performing bulk operations; Avoid affecting processing efficiency and success rate due to server overload.
• For classified documents, it is recommended to submit them separately and encrypt them for storage, and then transmit them to relevant personnel after decryption. To prevent increased risk of information leakage.

IV. Choosing a suitable decryption scheme

If you have a small number of files to decrypt, and they are not confidential or sensitive, you can opt for an individual decryption process. It is faster and more straightforward.

If your files are numerous, or involve confidential data, consider using the batch upload feature for efficiency and security. However, carefully manage the number of files being processed at once to avoid server overload issues.

V. Frequently Asked Questions and Answers

Q: Why can't I open the file I uploaded?

A: First, check if your network connection is normal; Secondly, confirm that the file path you uploaded is correct and that the size is within the allowable range (based on the page display).
