Can Excel activities also operate on and overwrite CSV files?

Hello,
I am using StudioX 2022.4.6.

Can activities for Excel operations, such as For Each (in each sheet), For Each (in each row), ReadCellValueX, and WriteCellX, also manipulate and overwrite CSV files?

I resolved it myself.
When reading a CSV file with the ReadCellValueX activity, it seems that using “formatted text” allows you to save the changes.
