Google sheets allow you to create spreadsheets that can store various types of data. You can use the stored data to perform complex calculations and create visualizations. It can be tiresome to select the range of cells every time you apply a function or perform a calculation.
Renaming columns enables you to use your column name instead of the range of cells. This eases your work and saves you time. Sometimes, the header is also included by mistake while performing calculations.
You can avoid this by separating the column names from the rest of the data. Freezing the header or renaming your column will help you achieve this. Also, note that you cannot rename the first row, i.e., the fixed header set by Google Sheets.
