How to tell them apart
に marks a target or point something goes to or happens at, while で marks the setting where an action unfolds. The test is whether the place is a destination or a spot of activity: 学校に行く takes に because school is the goal, but 学校で勉強する takes で because studying is what happens there. Swapping them sounds odd, since でに行く implies acting at a destination rather than heading to it.
- に Use に when naming a destination, direction, or specific time an event occurs.
- で Use で when naming the place where an action happens or the means used.

に ni
Marks a place, point in time, or direction of movement
The particle に marks the place, moment, or direction toward which something happens or is directed. It follows a noun, as in a time like １１時 or a destination or target like きみ. It also appears after a verb stem in patterns like 一人になりたい, where it points to a resulting state or direction.

で de
Marks the location of an action, or the means or method used
The particle で follows a noun to mark the place where an action happens, or the means, tool, or method used to do it, as in イタリア語で (in Italian). It can also mark a role or capacity, like a bit part. It attaches directly after nouns.
