If you want to hide multiple columns on a Microsoft Excel spreadsheet, you can use the tool Group.
Step 1. Open your Microsoft Excel spreadsheet
On a PC or Mac, you just have to double-click on the file.
Step 2. Select the columns you want to hide
To do this, click on the letter above the column, and then drag the mouse to include the second column. Both columns should now be highlighted.
If you don't want to hide entire columns, just select the cells you want to hide (instead of the letters at the top of the columns)
Step 3. Click the Data tab
It is at the very top.
Step 4. Choose Group
This option is located near the upper right corner of the screen in the menu Plan.
Step 5. Select Columns in the Group menu and click OK.
If the popup menu Group does not appear, go to the next step.
Step 6. Click - to hide the columns
This option is to the left of the gray square above your worksheet. The columns will disappear and - will turn into +.
