Excel is a powerful tool for data analysis and management, and one of its most useful features is the ability to lock columns. Locking columns allows you to protect your data and ensure that important information remains visible and unchanged while you work on other parts of your spreadsheet. In this guide, we will explore various methods to lock columns in Excel, catering to different user preferences and spreadsheet complexities.

Method 1: Using the Format Cells Option

One of the simplest ways to lock columns in Excel is by using the Format Cells option. This method is ideal for basic locking needs and is suitable for a small number of columns.
