Group (outline) data on a worksheet

The Group feature that lets you outline your data isn't available in Excel Online. When you open a workbook that already has grouping applied, you can view and interact with the grouped data, but you won't be able to change the grouping or group other data.

If you have the Excel desktop application, here's how you can use it to change the groups or add grouping there:

Click Open in Excel and follow the steps to use grouping to outline your data.

If you don't have the Excel desktop application, you can give it a try. Or, you can buy it here, when you're ready to switch.
