Thanks for the help. I tried two things - changing it to one item/row, and using the create JSON module as you recommended and now it works (not sure if one or both of those changes helped) but only when im working with a single row, but i cant get it to work properly with multiple items (i have a collection of arrays i want to add as a row each into glide). ive read through Set columns in multiple rows - Glide API as that post seemed relevant, but im not familiar with the iterator/aggregator and parse JSON modules (Im unfamiliar with Make.com really) so i feel like this are relevant but not sure if that would help me to get this to add multiple rows to Glide?
