JSON returns Column Names separately from the Rows

I have a REST API that returns something like the following:

entity":
{
“items”:
[
{
“tableName”:
“mytable”
“count”:
7995
“columnNames”:
[
“c1”,“c2”,“c3”,“c4”
]
“rows”:
[
[r1c1value,r1c2value,r1c3value,r1c4value],[r2c1value,r2c2value,r2c3value,r2c4value],[…],[…],[…],[…],[…],[…],[…],[…]
]
}
]
}

When I refer to jsonPath($, “entity.items[*]”) it gives me columns as an array of columns and the rows are an array of rows.

How can I parse this so that I can map it to a Mapper to put into SQL?

Thanks
