I am doing a data load.

The data was exported from the old system with data for each part in a single row

The data for the new system needs to be in multiple rows for a single part to be imported. How can I automate this process in excel?

For example (this is a simple example the real one has 18 rows per part for the new system)

Old data:

PartNameA PartNumberA PartDescriptionA
PartNameB PartNumberB PartDescriptionB
PartNameC PartNumberC PartDescriptionC

I need the new data to show:
PartNameA
PartNumberA
PartDescriptonA
PartNameB
PartNumberB
PartDescriptionB
PartNameC
PartNumberC
PartDescriptionC

Thanks!
