Due to the nested array, processing your data in make will require more than n operations for n bundles. There are two workarounds to this problem: If you have an enterprise account, you can write custom IML functions in javascript. This would allow for the data processing to occur in 1 operation regardless of the bundle count. Use a service like 0codekit.com or autocode.com to host a custom javascript solution, then use an HTTP module to post the aggregated bundles to the endpoint.

Context: Stack Overflow question (score 2, has accepted answer): In Make.com / Integromat, I have an API call result with the following format (I have actually much more bundles, but that is not relevant for my question): > Bundle 1 : { "InvoiceId" : 1111, "InvoiceElements" : [ { "Id":1, "Description" : "Fish" , "Price" : 10}, { "Id":2,"Description" : "Meat" , "Price" : 30}, { "Id":3,"Description" : "Tomato" , "Price" : 4} ] } > Bundle 2 : { "InvoiceId" : 1112, "InvoiceElements" : [ { "Id":1, "Description" : "Fish" , "Price" : 10}, { "Id":2,"Description" : "Meat" , "Price" : 30}, ] And I cannot manage to transform this 2 Bundle-object into a 5-row array, or even a 5-Bundle output , without generating 2 operations (or N operations if I have N invoices/bundles !) I simply would like t obtain a result like this : [ { "InvoiceId" : 1111, "Id":1, "Descriptio
