Spreadsheet Proper Name Corrections

I have a spreadsheet of fewer than 1,000 rows and up to 10 columns that holds copyright-related data. Many of the entries are proper names—authors, publishers, imprints, and similar fields—and several of those names have been typed inconsistently.

Your task is to go through every row, verify the spelling of each proper name, and correct any mistakes you find. I need the file returned in the same format, with the corrected names clearly identifiable (track changes, a separate “Corrected” column, or cell highlighting—choose whichever method is fastest for you and keeps the sheet clean).

Because the sheet is small, I expect fast turnaround and a very high level of accuracy. No changes are needed for general typos or technical terms; you can focus exclusively on proper names.

Deliverable: the updated spreadsheet with all proper names spelled uniformly and an indication of every change you made.
