Merge cells dependent on a condition

teat me as a beginning beginner pre-beginner level user

4 columns - uniqueid, email, name, company

I will export to CSV and can import only the first 3 into the program.

Before exporting, within Excel, how would you attack this :

Where name is missing, populate it with the company if it exists

uniqueid,name,email,company 00011,CindyLou Who,cwho@company.tld, 00012,,grinch@company2.tld,Grinchdom 00013,,sally@company3.tld, 00014,Patrick,pat@spongebob.tld,Spongey 00015,,bob@spongebob.tld,Spongey 

desired:

uniqueid,name,email 00011,CindyLou Who,cwho@company.tld 00012,Grinchdom,grinch@company2.tld 00013,,sally@company3.tld 00014,Patrick,pat@spongebob.tld 00015,Spongey,bob@spongebob.tld
