How to export SharePoint Online list and import into a new tennant

Question

Is there any way to export SharePoint Online lists and import into an another site?

There was an option for that in on-prem installations but I did not find any in SherPoint Online.

(I need something like a file what can be saved and published in an another SP site, this is how the SharePoint designer worked.)

Answer 1

There are some options for your reference:

1. Use "Save list as template" and include content, then upload to destination site list template, then create a new list using this template.

2. Use Third-party tool as ShareGate to migrate the list.

   Reference: Copy a List in SharePoint or Office 365

3. Use PowerShell and CSOM to go through the source list and add items to destination.
