Final answer:
The displayed value of "#####" in an Excel worksheet cell typically indicates that the cell content is too wide to be displayed fully.
Step-by-step explanation:
The displayed value of "#####" in an Excel worksheet cell typically indicates that the content of the cell is too wide to be displayed fully. The ##### is Excel's way of indicating that the cell content is too long to fit within the default column width. To display the full content, you can adjust the column width by double-clicking on the column separator or by using the AutoFit feature.
