Greetings, dear readers. In todayâs digital age, data security and privacy are of utmost importance. Whether you are a student, a professional, or a business owner, you deal with confidential data on a daily basis. One of the most popular software for storing and processing data is Microsoft Excel. However, sometimes sharing an Excel sheet with others can pose a risk. This is where Excelâs cell locking feature comes into play. In this article, we will guide you through the process of locking cells in Excel and how you can use this feature to protect your data.
đ Understanding Cell Locking in Excel
Before we dive into the details of locking cells in Excel, let us first understand what cell locking means. By default, all cells in an Excel sheet are unlocked. This means that anyone with access to the sheet can make changes to the cells, including deleting or modifying them. However, it is possible to lock certain cells in Excel to prevent changes from being made to specific cells or ranges of cells.
đ How to Lock Cells in Excel
The process of locking cells in Excel involves two steps:
| Step 1: | Select the cells/range of cells that you want to lock. |
