Download ObjectTools 5.0 for Mac from our website for free. This Mac app was originally designed by Aparajita Fishman. The program is included in System Tools.
From the developer:
ObjectTools is a plugin that gives you a full suite of commands for managing an object. An object is a sort of a BLOB, but instead of accessing anonymous items sequentially or by offset, you access each item by name. You can directly access, modify and delete array elements within an object without copying the array into a variable.
