Questions
Good to know
Which line stays?
The first one, in the order of your list. If you choose ‘The last’, the last one stays. The order of what remains doesn’t change.
Can I compare on one column, such as the email address?
Yes. Choose ‘Rows of a table’ and click the column letter of the email address. Two rows with the same email address then count as duplicates, even if the name is different.
Does my list go to a server?
No. Everything happens in your own browser.
