Topic: Changing multiple and various species names using a batch update?

I am hoping it will be possible to design a batch update that will use a simple spreadsheet to change an existing species name to a new specified species name for the TOK keys present.

All the other original data remains unchanged, the batch update will correct a minor species name error that happened during importing.

Any help with this would be wonderful, maybe someone else has already designed a batch update that they would be prepared to share?
Many thanks,
