Thanks @JR Boulay ,
A graphical user interface (GUI)-based Acrobat JavaScript utility has been developed to streamline the workflow for manipulating dynamic PDF form files. This add-on, integrated into the Tools pane of Acrobat Pro, enables users to perform folder-level batch processing. This functionality allows for the simultaneous injection or deletion of JavaScript code or scripts into multiple fields form documents, thereby automating a repetitive task that would otherwise require manual entry into individual fields or forms within each document.
