The Coruscant Datacard is one of the hardest collectibles to find in the game. Here is the exact location.
How to find the data card on Coruscant | The Skywalker Saga
Some data cards can be found extremely easily in LEGO Star Wars: The Skywalker Saga, but others are a pain. A particularly tricky data card can be found on Coruscant.
The card is in the federal district. You need to go to the northwest corner of the map, where you will find a black door. There should be an orange cable running from it, which you should follow to a valve in the ground.
You can destroy the valve with an attack, which will lead you to a path consisting of some ledges. Follow it all the way to the end – it's quite long. On the last stretch of the road, you'll find a red force field with the Data Card behind it.
