Unhide columns not working (Issues & Solutions)

Occasionally, you might come across some hidden columns that cannot be unhidden using the usual methods, such as the Unhide option from the right-click menu or the Unhide Columns feature in the Format menu. There are generally two reasons why the columns won’t unhide:

• Column width is very small
• Worksheet is protected

Column width is very small

Sometimes, you may see a column hidden as shown in the below screenshot. But in reality, the column width is set to very small,which makes it appear as if the columns are hidden. When you attempt to unhide the columns using the Unhide option from right-click menu or Unhide Columns feature from the menu, the column remains hidden.

To solve this issue, please do as this:

Select the columns that contain the columns in between that you want to display. Then, put your mouse in between the column headers that have the hidden columns. Here, I will hover the mouse between Column C and E, and you will see a double-sided arrow. Then, hold the left key of the mouse and drag it to the right to expand the hidden column. See the demo below:

 Worksheet is protected

Another possible reason why you are unable to unhide columns is that the worksheet you are working on is protected. This can occur if someone has applied protection to the worksheet before sharing it with you. As a result, when you want to apply the Unhide option from the right-click menu or the Unhide Columns feature from the Format menu, these options become grey and unable to use.

In this case, to solve this issue follow the below steps:

1. Go to the Review tab, and click Unprotect Sheet, see screenshot:
   
2. In the popped out Unprotect Sheet dialog, please enter the password if you know, see screenshot:
   
3. Then click OK to close this button. Now that the worksheet is unprotected, you can use any of the methods mentioned above to unhide the columns.
