Summary
In Excel, select the columns you want to group. Go to the Data tab. Open the Outline drop-down menu and pick “Group.” Use the plus (+) and minus (-) buttons that appear to expand and collapse the group.
If you organize a spreadsheet by columns, you may only want to work with specific columns at one time. In Microsoft Excel, you can group columns and expand and collapse them as you work. We’ll show you how to do just that.

Not only can you group columns in Excel, but you can also create subgroups or more than one group in the same sheet. This allows you tosee only those columns you needwhile hiding or collapsing the others.
How to Group Columns in Excel
Togroup columns, you’ll need the columns you want to group next to each other. You can’t group nonadjacent columns.

Select the columns you want to use by dragging your cursor through them. Alternatively, you may select the first column, hold your Shift key, and then select the last column in the range.
Head to the Data tab and open the Outline drop-down menu on the right side of the ribbon. Click “Group” in the menu or select the Group drop-down arrow and pick “Group” there.

You’ll then see your selected columns grouped with a line and minus sign (-) button above them. you may use the minus sign button to collapse the group and the subsequent plus sign (+) button to expand it again.
You’ll also notice buttons labeled 1 and 2 on the far left, which you’re able to also use to expand and collapse the group. However, the number buttons change a bit if you add a subgroup or another group in your sheet, as we’ll describe next.

Create a Subgroup
To create a subgroup of alarger group of columns, you follow the same steps as above. Select the columns, go to the Data tab, and pick “Group” in the Outline drop-down menu.
What changes when you create a subgroup is the way the number buttons work. After you create a subgroup, you’ll see another button labeled 3. This is because there is now another level.

You can still use the plus (+) and minus (-) sign buttons to expand and collapse each subgroup and group. But with the number buttons, you can quickly expand and collapse all groups on a level using the number button corresponding to the group level.
Create Another Group
If you want to create another separate group of columns in your sheet, you can do this as well. However, these groups can’t be right next to each other.
For example, if you group columns A through C and D through F, Excel puts them all into the same group.

You should have at least one column between groups or consider creating a large group and then subgroups, as described above.
Also, when you have more than one group, the number buttons affect all groups on that level. For instance, if you select button 1 to collapse a group, this collapses allgroups on that level, as shown below.

Ungroup Columns in Excel
If you want to return your columns to their original states, you may simply ungroup them.

Select the columns in the group, head to the Data tab, and open the Outline drop-down menu. Click “Ungroup” or select “Ungroup” in the Ungroup drop-down box.
You’ll then see your columns ungrouped.
You can alsoremove just certain columnsfrom a group. For example, we have columns A through K in a group and want to remove columns F through H from that group.
To do this, we select columns F through H and click “Ungroup” on the data tab.

You’ll then see that the rest of the columns remain in their group(s) with buttons and all.
By grouping columns in Excel, you can reduce large amounts of data into workable sections. Keep this feature in mind with your next spreadsheet.
