Building off the other comments, I'd suggest trying to get rid of the
intermediate JSOn format and also just focus on a single row at any given
time.

For an update the first argument to the metacommand could be the unique key
value present in the previous result. The resultant UPDATE would just put
that into the where clause and every other column in the result would be a
SET clause column with the thing being set the current value, ready to be
edited.

DELETE would be similar but without the need for a SET clause.

INSERT can produce a template INSERT (cols) VALUES ... command with some
smarts regarding auto incrementing keys and placeholder values.
