I’m having issues with datalinking larger excel tables into CAD.
We’re investigating if it is possible to insert a table through Dynamo instead. Has anyone been successful with this? We would ideally want the table to update dynamically with the Dynamo script and not re-inserted every time (but can still entertain a less than ideal scenario 
)
Yes, this is definitely doable! Caveat is that the nodes for working with tables weren’t added until Civil 3D 2025, so you’ll need to either be using 2025 or 2026.
Assuming that isn’t an issue, then the node you’re looking for is Table.ByPointContents. If you right-click on the node and select Help..., there is some documentation and a sample that you could try out to start with. You can click the little insert button on the sample to drop it into the workspace:
This doesn’t include the Excel part, however. Here’s a sample you can try that shows how to import some example data.
