Workbook - Compress Graphs and Reports

Ribbon bar. Select the Workbook tab. In the Tools group, click Compress Graphs and Reports...

Classic menus. On the Workbook menu, select Compress Graphs and Reports...

...to specify that graphs and reports in the workbook will be compressed in order to make the workbook smaller in size and speed up copying workbook files on a network. A check mark is displayed next to this command to indicate that compression is in use in the workbook. Selecting the command again toggles the compression state on and off. Workbooks that were previously saved uncompressed will remain uncompressed until you open the workbook and select Compress Graphs and Reports from the Workbook tab or menu.
