[Koha] import question

[Maintenance]

We just built a KOHA server and would like to import our other Library
manager data.

We are currently using one called  "Handy Library Manager" made by "Primasoft"

We exported the data from that system and it is just a excel file

We have about 14K books.

We don't want to remake the database in KOHA by hand.

Is there a way to import it into KOHA?

If needed, I can give a copy of the DB export so you can see what we have.

Thanks
Jason
