Data.ImportExcel node error

Hi everyone.
Looking for some help on my Dynamo script- the script itself is supposed to take X, Y and Z coordinates of a road alignment (Civil 3D) from Excel and then import them and connect them into generic adaptive family. For some reason an error appears “Warning: Data.ImportExcel operation failed” on the Data.ImportExcel. This problem seems to happen only on my computer, as the script and the same Excel file was tested by a colleague and there was no error. The only visible difference is that my computer has the 2019 office version but my colleague has 2013 version of office.
Looked through some topics on this forum, but no solution to the error.
Any ideas?
