welcome, @wwcanoer to the community!
Excel does have a remove duplicates tool, on the “Data” ribbon:
Bitwarden import neither overwrites nor “merges” entries. In the premium plan ($10/yr), there is a reused passwords report on the web vault, which can help you find duplicate entries, but it too does not automatically remove entries from your vault.
There is a long-standing request for a duplicate removal tool/report that you might consider voting for.
I think that depends. When I first started with a password manager, I came from “paper & pencil” - and just entered everything by hand, one by one.
(for those who may read it also: I found, logging in to my services and changing the password at the same time as I entered it into Bitwarden, was quicker as first entering everything and after that go through everything again and changing all passwords…)
I guess no duplicate tool can help you with that now…
So, good luck then!
PS: If you don’t create new chaos afterwards, the good thing is, the duplication tool is probably never needed again when everything is set up…
I switched from LastPass to Bitwarden. LastPass has had a duplicate password finder for years. Should I go back to LastPass to fix my duplicates?
Though Bitwarden has no automatic removal or merge for duplicates - a duplicate finder for passwords is there: the “Reused Passwords report” (see here: Vault Health Reports | Bitwarden Help Center).
+1 in 2025, please
