How to Manage Communities
Hi
how can I use this to update the existing records -- You have the ability to export the data from accounts explorer (refer the below screenshot)

Do I need to first extract the existing accounts to a CSV, update it offline and then upload? --
Yes, you can do this using the data loader.

I already have lots of accounts populated and I dont want to delete them, just update a certain field -
Never bother about deleting the data, you can update the certain field using the csv with Id as identifier using the dataloader.
Any Resources?
