Cells in Google Sheets can be formatted so that the numbers stored in them are displayed as needed. For example, the cell number can be formatted to display as a currency so that it includes the dollar symbol. Or it can display as the percent value or a time in days. To change a cell's number formatting, select the cell or cells, open the Format menu, hover over number and choose the Format type from the Menu. Cells, rows, and columns in Google Sheets can be added, changed, moved, and deleted. To add a single cell, row or column, right-click on it. For rows, right-click on its number, and for columns right-click on its letter and choose the appropriate Insert option from the menu. When a cell is inserted, the existing cells are shifted right or shifted down. Rows can be inserted above or below a selected row, and columns can be inserted to the left or right of a selected column. Cells, rows, and columns can also be deleted. When cells, rows, and columns are deleted, the data contained in them will also be deleted. You can also resize cells. To resize a row or column to fit the data in it. Double-click on the right edge of the column or bottom edge of the row, to automatically apply the proper size. Alternatively, right-click on the row or column and choose resize. And enter the desired size in pixels or select fit to data. To move a row or column, select the letter of the column or number of the row, and the pointer will change to a hand, click and hold, then drag the column to the left or right, or drag a row up or down. Cells can also be frozen. This can be useful if you want to view a header row while scrolling through many rows of data. Both rows and columns can be frozen. To freeze a row or column, select it, open the View menu, hover over freeze, and then select one row slash column, two row slash column, or up to current row slash column. A thick gray line will appear at the end of the frozen rows or columns. This line can be dragged later to change the range of cells that are frozen. Freezing header rows at the top of a sheet also ensures that these rows are excluded if you sort your sheet.
