I am trying to mass change my email in username field, but I failed to do so. I exported my whole vault as csv, did the change but import fails. What I did was, export vault as csv, open in Excel, change [email protected] to [email protected], save file and import in web vault page. Then I get below error.
Not related to the issue, but just a warning:
A re-import will not replace (=overwrite) existing data. Instead the imported data will be added to the database.
The result will be that all entries will exist twice; unless of course you import them several times. So if you would import the data x times than you would have every item with x copies.
