Sure, I can help you with that! Here's how you can remove the blank space in front of text in multiple cells at once:

1. Select the range of cells that you want to remove the blank space from.
2. Click on the "Find & Replace" button in the "Editing" group on the "Home" tab.
3. In the "Find and Replace" dialog box, click on the "Replace" tab.
4. In the "Find what" field, type a single space character (press the spacebar once).
5. Leave the "Replace with" field blank.
6. Click on the "Options" button to expand the dialog box.
7. Make sure that the "Within:" field is set to "Sheet" and the "Search:" field is set to "By Rows".
8. Check the box next to "Match entire cell contents" to ensure that only cells with a single space at the beginning are affected.
9. Click on the "Replace All" button.

This should remove the blank space from all the cells in the selected range at once. Let me know if you have any other questions!
