Best way to manipulate excel stimulus sheets

I have been working on designing experiments in PsychoPy for a few months, however the method I’m using to load the Stimuli into lists in Python doesn’t seem to translate well into JavaScript. I was wondering if there was a better way to go about loading them? Here is what I have been doing so far:

I use a loop. Take a look at Brookes template for how I do this.

Hi, I have tried implementing the list.append() that you suggested, however when I try to run this online it tells me that this is not a function. Any suggestions?

Check the code_JS section of my crib sheet for how to define .append as .push.

Best wishes
