how to change read only cell to editable cell
Welcome @Nur_Muhammad_Fuadi
Is the cell you are trying to edit part of a column with a column-only data type such as Autonumber, Column Formula, Related row lookup, or Related row rollup? …or a System data type like Created by/Updated by or Created at/Updated at?
Cells in these types of columns are read-only. More info about column-only data types here:
If you have Project Management settings enabled on a worksheet, parent row cells of project management columns such as start date, end date, duration, and % percent complete are read-only because they are auto-computed from child cells. More info about Project Management settings here:
