just do
Be careful: I noticed that if you use table properties VariableUnits, then it gets lost!!

From my experiments, jsonencoding a table, writing, then jsondecoding the file returns an equivalent array of structures. You can convert back to a table via struct2table but that assumes you knew it was a table to begin with.
So, I guess you would have to do it "manually" by changing each table to output into, say, a structure with a table field and a unique ID field so that after this structure (with the ID and table field) was read back in, you could parse the returned item for such structures and just, now with foreknowledge, convert the table field back to a table via struct2table.
Not very pretty
