There are a few ways to freeze columns in Google Sheets. The easiest way is to select the column you want to freeze and then click on the freeze column button at the top of the column. This will freeze the column so that it stays at the top of the list no matter how you scroll down.

Another way to freeze columns is to use the freeze panes feature. This feature will freeze all of the columns except the one at the very top. To use this feature, click on the View tab and then select Freeze Panes. You can then select the columns you want to freeze.

A third way to freeze columns is to use the split panes feature. This feature will split the spreadsheet into two panes. The column on the left will be the frozen column and the column on the right will be the unfrozen column. To use this feature, click on the View tab and then select Split Panes. You can then select the columns you want to freeze.
