If you work with Microsoft’s Excel regularly, you may notice a green triangle in the Excel cell and wonder what it does, if you can control it and how to remove it. The simple answer is that it is an error checking feature in Excel. Whenever you see the green triangles it means that Excel has found something in the cell that could be a risk.
When you work in Excel, by default, it automatically identifies all issues, such as incorrect data in the cell, problems with formulas, etc. So, you see green triangles (by default) shown in the top left corner of these cells.
This begs the question “What do red and green triangles mean in Excel?”
Red and green triangles are used in Excel to indicate possible errors in a cell’s contents and the presence of user comments in the cell. In addition to the color, the triangle appears in different corners of the worksheet cell. The green triangle appears in the top left corner.
A green triangle in the upper-left corner of a cell indicates an error in the formula in the cell. If you select the cell, the Trace Error button appears. Click the arrow next to the button for a list of options. For more information, see Detect errors in formulas.
While I was reading we ran into the question “What do the two colored triangles in a cell mean?”.
The two colored triangles that can appear in a cell are green (formula error), and red (comment). A green triangle in the upper-left corner of a cell indicates an error in the formula in the cell.
How do I remove a green triangle from a cell?
Ignore Error- Ignores the error (and removes the green triangle from that cell only) Edit in formula bar- takes you to the formula bar so that you can make a change Error Checking Options- takes you into the Error checking options where you can control the green triangles and what they highlight, or switch them off completely.
