Data cleanup using API's



Hi Guys. I’m looking to hire a developer to help with some data cleanup. We have around 9.3k company records. Only around 1.3k have domain names. There are 8.4k contacts with email addresses that are associated with these companies. I want to use the associated contact email address extension to propogate the company domain. I can export records to excel and do the cleanup there, however, I can’t get the data back into Hubspot without creating duplicate company records (that would in turn not be associated with the relevant deal records). I also have around 1k duplicate companies that need to be merged (rather then deleted). It would take forecvet to try to do all this manually so I’m hoping someone is able to achieve this using the Companies API? If so, please get in touch as I’d like to hire, cost dependent, some development resource to help resolve this.
