I need to cause a range of cells to have the green triangle(number stored as text). I have to do this by: 1. format the cell as text 2.Paste the data 3. Double clicking every one of the cells The reason I'm doing this is because the system can only accept data which has the green triangle. Is there any excel macro that can double click the range of cells?

The data needs to have a green triangle, else the system will show this error after I have uploaded the file without a green triangle:
Error reading in excel file.

I have already double-confirmed this, tried this with and without 1 green triangle. So is there any way without meddling with the system( I have no rights to do so)?
