[Koha] Excel to Koha year wise filtration problem

How can we add year in marc tag 008 for the bulk data migration from excel? like we do 260$c for the year?. The reason why I am asking this, year-wise filtration works only when we add the year in marc tag 008 07-10 (thanks to IGD sir). we want to import all excel data to koha with year-wise filtration. please help us *Mahesh Palamuttath* M.Phil.
