Excel schedules to Revit

[Yna_Db]

Hello, quick answer: you will probably need to link your datas using GUID, see this for instance:

Excel to rooms by ID

The elements IDs can change but the GUIDs are stable. There is a node called Revit ID in the Hot Gear package that will give you these GUIDs. For more explanation, please see on Revit forums: http://forums.autodesk.com/t5/revit-api-forum/unique-id-vs-elementid-which-identifier-to-stored-in-the/td-p/4962636 And also, Id to Element from Archi-lab Grimshaw accepts GUIDs

Using a dictionary could also be necessary:

Pairing Data according to criteria - Dictionary

I did not replicate this situation but to me, a Dictionary.ByKeysValues node (spring nodes) makes sense here: Walls have a tag (=keys) to identify elements in Excel sheet (=values), and you need to search by ‘Pier Number’ (=search keys). See in the thread you mentioned:
