How to execute a formula in GOOGLE SHEETS notation, assembled from text fragments, using a user-defined function?

Question

Google Sheets

For example: =RUN ( "=SUM("&A2&")" ) rather than using the equal sign =RUN ( "SUM("&A2&")" )

Simple math expressions are simple.

SCRIPT
function RUN(formula) { return eval(formula) }

=RUN("8*2*3") I get 48

There is no such built-in function in the tables themselves, I know, can it be possible to implement this with a Script? But only as a custom function.

Just sticking the collected formula into a cell from the script is no problem.

Tried from a custom function.
use cell A1 to insert a formula into it, and then pick up and return the result, but was denied access when executing the script.

Answer 1

Unfortunately, there is no such interpreter in Tables.
