how to delete imported csv using mass delete

AI generated answer (using internal Slack threads):

To delete imported CSV files using mass delete, you can use the following methods: 1. URL Navigation Method: You can navigate to the URL that deletes CSV imports, plugging in the target ID. The URL format is

/app/setup/assistants/nsimport/savedimports.nl?method=delete&recid=###

. You can make a list of URLs in Excel and click each one. However, be aware that this method will not prompt for confirmation to delete and you should avoid opening hundreds of pages at once to prevent being timed out. 2. Custom Mass Update Script: You can create a custom mass update script where the script is a simple record.delete. Deploy the mass update to the desired record type. From the UI menu, initiate “mass update” and create saved search criteria for the records (rows) you wish to delete. 3. Overwrite Sublists Option: If you have uploaded a CSV file with incorrect data, you can try re-importing/updating the data, but this time make sure to check the "OVERWRITE SUBLISTS" option under the Advanced options section while importing. This should remove the extras and keep only what you have in your new CSV file. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
