After you have imported your data select all columns and rows; choose A hold down your shift key and go over to the end of your data so everything is highlighted.
Now right-click on the highlighted fields and from the sub menu choose Format Cells.
In the Format Cells window click the Alignment tab, choose Center from the drop down box under Horizontal and click OK.
Now all of the data will align in the center of each cell to make the data more presentable. This is especially handy when you are printing out the reports.
