While you have Excel open, it is constantly checking in the background for potential errors in your worksheets. If an error is located (or, at the least, what Excel thinks is an error), then the cell is "flagged" with a small green triangle in the upper-left corner of the cell.
If you don't want Excel to check for errors, you can turn the feature off by following these steps:
Figure 1. The Formulas area of the Excel Options dialog box.
Any existing green triangles should disappear, and Excel stops checking for errors.
Understand that turning off error checking in this manner affects only the way that Excel works on your own system. If you share the workbook with someone else and they open it on their system, the display of the "flags" is controlled by the setting on their system.
