Excel Car OEM Data Entry

I already have a spreadsheet holding roughly 750 rows of vehicle information—each row contains the make, model and year. The only thing missing is the correct OEM number. Your job is to open the file, add a new “OEM Number” column, and populate it by searching reliable online sources (a quick Google search or a manufacturer’s parts catalogue usually does the trick).

Deliverables
• Updated Excel sheet with an OEM number filled in for every vehicle
• Sources kept handy in case I need to verify any entry

I’ll run random spot-checks, so accuracy matters more than speed, though I’d like the completed file back as soon as realistically possible. If you’re comfortable with Excel and systematic web research, this should be a smooth task.
