Why You Need to Protect Excel File from Opening without Password
The need to protect Excel files from opening without a password can arise for several reasons. Here are a few scenarios where password protection can be beneficial:
1. Confidential Information: If your Excel files contain sensitive or confidential information, such as financial data, customer details, or business strategies, it is essential to protect them. This ensures that only authorized individuals can access the data, reducing the risk of data breaches or leaks.

Unauthorized access to such files could result in theft or misuse of ideas, designs, or proprietary information.
