[Koha] Need help in correcting migrated database

In my migrated koha system I have got to do many corrections and additions. Some fields got values wrongly and some of the fields got no values. But the source spreadsheet database has got correct values. I was thinking about a method by exporting the biblio, items and biblioitems tables to excel, make corrections/ additions to these excel files, truncate the biblio table which will make a cascaded truncation; import the excel files to the corresponding tables. If I import , in which order of tables should I import to. Run zebra-rebuild again. Will this method work?
