How to delete bulk Master Data like Customers?

Hi friends, I’d like to delete testing data (20,000+ customers) from ERPNext.
But it only allows me to delete max 500 from the Customer List.

Is there anyway I can do it in one go?

There is no such provision to delete this much data. If you have created testing data, then you can reinstall the site. It will flush all the records and you can start with a fresh site with no records.

Thanks for your reply @Sangram, is there anyway I can reinstall the site from a hosting account in Frappe? because it’s not self-hosted, I don’t have access to bench.

Fixed. Need to ask the Frappe Team to re-install & reset. thanks for the help.
