De-duplication

De-duplication

Is it possible to remove multiple rows at once?

Example, If i have my master database of contacts uploaded to Zoho sheets, and I want to remove any unsubscribers on a weekly basis, can i do this in an efficient way?

So say i want to remove 100 random (but specific) rows at once from the worksheet, is there a simple way to do this?

I normally do this in Access and run what we call a De-dupe - But im looking for an online solution and I dont want to have to upload a fresh database every week - I need a way to do this efficiently and online please.

Thanks in advance
