Hello. You need to add text to the existing ones in Excel cells. What formula to use?

Question

excel

There is a table with data in the cells, you need to add more values. How can this be done?

Answer 1

None.
The formula cannot change another cell. The formula cannot exactly change itself - it can only calculate a new value.
This is done either by a formula in a separate column and then replacing the original column with calculated values, or by a VBA procedure.
