That's with a loadable JSON1 extension, which one won't find e.g. in Android.
Though checking now for this, someone has packaged a later version of SQLite with this extension [1]. I wonder if there is any possible performance advantage when using a system provided SQLite vs. one installed with the application?
I think a better sqlite page about the concept of serializing things in your database is the fact that sqlite has json support.
