First lest`s start by simply HIDING some rows and Colums. If you wish to Delete see that section.
You usually hide a column or row to conceal or protect data and formulas. But you can also hide unused regions of a sheet to keep users from exploiting unused areas or to help keep them on task by not allowing them to wander. By hiding unused rows and columns, you present a sheet that focuses on just the work area. To demonstrate, we'll use the sample worksheet shown in Figure A, which has a small working area and a whole lot of unnecessary rows and columns.
To hide unused rows in Excel, select the row beneath the sheet's last used row. (Select the row header to select the entire row.)
Next, press Ctrl + Shift + Down Arrow to select every row between the selected row and the bottom of the sheet.
Then, choose Row from the Format menu and select Hide. Repeat this process to hide unused columns, only select the column header in the first empty column. Press Ctrl + Shift + Right Arrow and then choose Column from the Format menu instead of Row.
How to Quickly and Easily Delete Blank Rows and Columns in Excel
If you have a lot of blank rows in your Excel spreadsheet, you can delete them by right-clicking each once separately and selecting “Delete,” a very time-consuming task. However, there’s a quicker and easier way of deleting both blank rows and blank columns.
First,let`s remove the blank rows, Deleting blank columns is a similar process that we’ll show you later in this article.
1) Highlight the area of your spreadsheet in which you want to delete the blank rows. Be sure to include the row just above the first blank row and the row just below the last blank row.
2) Click “Find & Select” in the “Editing” section of the “Home” tab and select “Go To >> Special…” on the drop-down menu.
3) select “Blanks” and click “OK.”
All the cells in the selection that are not blank are de-selected, leaving only the blank cells selected.
4) In the “Cells” section of the “Home” tab, click “Delete” and then select “Delete Sheet Rows” from the drop-down menu.
All the blank rows are removed and the remaining rows are now contiguous.
You can also delete blank columns using this feature. To do so,
1) select the area containing the blank columns to be deleted. Be sure to include the column to the left of the leftmost column to be deleted and the column to the right of the rightmost column to be deleted in your selection.
2) Again, click “Find & Select” in the “Editing” section of the “Home” tab and select “Go To Special…” from the drop-down menu.
3)Select “Blanks” again on the “Go To Special” dialog box and click “OK.”
Again, all the cells in the selection that are not blank are de-selected, leaving only the blank cells selected.
This time, since there are no blank rows selected, only blank columns are selected.
4) Click “Delete” in the “Cells” section of the “Home” tab and then select “Delete Sheet Columns” from the drop-down menu.
The blank columns are deleted and the remaining columns are contiguous, just as the rows are.
This method for deleting blank rows and columns is quicker, especially if you have a large workbook containing large and multiple worksheets.
