Meaning
に and で can both appear after place nouns, but に often shows a place of existence or a destination, while で shows the place where an action happens.
Formation
Use place + に with います or あります when saying where someone or something is. Use place + で with an action verb when saying where someone does something.
Usage
Choose に for sentences like there is a desk in the room or I am at the station. Choose で for sentences like I study in the room or I wait at the station.
Nuance
に points to a location as a fixed point. で sets the scene for an action. This difference is very useful because many beginner sentences use the same place noun but need a different particle depending on the verb.
Comparison
部屋に机があります describes existence. 部屋で勉強します describes an action. The verb is often the best clue: います and あります usually go with に, while action verbs such as 勉強します, 食べます, and 待ちます often use で for place.
Common Mistakes
A common mistake is choosing the particle only from the place word. The place word is not enough. Check the verb: if the sentence is about existence, use に; if it is about an action happening there, use で.

に
に (ni) points to a specific time, destination, location of existence, or person related to an action. It is one of the most important N5 particles.
で
で (de) marks where an action happens or what means, tool, or language is used. It is different from に, which often marks existence or destination.
に vs へ
に and へ can both mark direction with movement verbs, but に focuses more on the destination, while へ focuses more on the direction toward it.
