Microsoft Excel is a powerful tool that has been designed to help users effectively manage vast amounts of data. One of the most frequently used features in Excel is filters, which is used to sort and categorize data based on specific criteria. However, it is common for filters to be accidentally cleared, which can lead to unwanted changes in the data. Fortunately, Excel offers a feature known as “Lock Filter” that allows users to protect filters from being altered by anyone other than the person with the correct password. In this blog post, we will explore how to lock filters in Excel to ensure the security and accuracy of your data.
Before we dive into the steps for locking filters in Excel, it’s important to understand why this feature is necessary.
