Solution 11: Clear the not used row/column

Sometimes users select/highlight the header of the row or column to add border or color. If you have mistakenly formatted (added border or color) to the entire row/column, Excel assumes some data is present there. Thus, it prevents adding new cells to the row/column. To prevent this issue, you have to clear the entire row/column.

Open the problematic workbook and go to the column next to the last column that has data in it.
Then, click the header (to highlight the entire column) and press Shift + Ctrl + Right Arrow to highlight all the columns that have formatting.
Now, in the Home tab, you will find the Borders menu under Font.
Choose “No Border“
Then, click on the drop-down arrow for Theme colors.
Choose “No fill“.
You can also press the “Delete” button to wipe any data mistakenly present on the unused cells.
Go to the Editing category.
By expanding the “Clear” option, choose “Clear Formats“.
Then, again click on the Clear drop-down arrow to select “Clear All“.
Save the changes you made to your workbook.
Close the Excel window and then re-open it to check if you can add new columns.

For Row:

Open the problematic workbook and go to the row next to the last row that has data in it.
Then, click the header (to highlight the entire row) and press Shift + Ctrl + Down Arrow to highlight all the unused rows right to the end of the sheet.
Now, in the Home tab, you will find the Borders menu under Font.
Choose “No Border“
Then, click on the drop-down arrow for Theme colors.
Choose “No fill“.
You can also press the “Delete” button to wipe any data mistakenly present on the unused cells.
Go to the Editing category.
By expanding the “Clear” option, choose “Clear Formats“.
Then, again click on the Clear drop-down arrow to select “Clear All“.
Save the changes you made to your workbook.
