Best way to export SQL Server database to sqlite (or SQL Server Compact)
You can use my Exportsqlce tool to create .sql files in sqlite format from a SQL Server database. Then run them using sqlite3.exe
Download command line tools from https://github.com/ErikEJ/SqlCeToolbox/releases/tag/3.5.2
Export2SQLCE.exe "Data Source=(local);Initial Catalog=Northwind;Integrated Security=True" Northwind.sql sqlite
Good luck!
(I also have SSMS and VS extensions that allow you to do this from a GUI)
