    You can use the ExtendScript Toolkit to export your expression as a .jsxbin file. You can take the contents of that file, wrap it in double quotes and stick it in an eval() function like this:


    My experience though is that doing this can incur a significant performance penalty.

    It’s hard to say what’s going on without seeing the original expression, the .jsxbin code and the error message (if any). Is it a long expression? You may be running into and issue with carriage returns.

    As a simple test, start with this:


    Running it through the binary exporter gives this:

    @[email protected]@[email protected]

    and this expression does in fact produce a wiggle:

    eval(“@[email protected]@[email protected]”);
