Modify or Update an Add-in

ClassDendrogram — Tue, 06 Jan 2026 01:05:05 GMT

This may be a silly question, but I can't seem to find the answer online. I created an add-in, which is saved as a .jmpaddin file in a folder. The JSL scripts function as expected when calling them from the add-in.

However, I made some modifications to the scripts, but they are not reflected when running them via the add-in, even after restarting JMP. I can't figure out how to open the add-in in edit mode to either reload the scripts or make other modifications.

Reopen the .jmpaddin file, with the new jsl in it, and JMP will ask you if you want to reinstall the addin

HI @ClassDendrogram ,

If you're on Windows, when you go to File > Open and find the jmpaddin file, there's an arrow that you can click that will give you the option to open using the add-in builder, where you can switch over the jsl script that is being used.

Thanks,

Ben

Hi @ClassDendrogram ,

the .jmpaddin file is just a zipped file with all of the files neede by the addin.
If you have chosen to reference additional files, that will probably not be updated automatically, depending on JMP Version.

Which JMP Version are you using?

How did you generate your AddIn, by JMP Addin Builder? Create Add-Ins with the JMP Add-In Builder

When you added a script in Addin Builder as a file (in JMP <= version 18), you need to add it again, to make the change effective.
This may have changed in JMP 19, but I did not test so far.
