Finally, thank you Jesus! I've been researching on this for the last 24 hours! The other methods out there was complicated for me and didn't give me what I wanted. The toObject was key for me in this tutorial. I will be using this step as part of my cutover work. Thank you Valentin, keep up the great work!

Hi Valentina..
This is what I was looking for - feed a bunch of input requests from external file. 2 follow up questions:
1) I presume the same concept works for CSV input as well.. Maybe some twaeks to concert CSV to valid JSON; similar to JSON.Stringify you used in this video
2) If I were to run this using Newman CLI and save the responses to a file (another video of yours), how does the file selection part work in CLI (in PM, you select the external file from a folder)?

[honeyclementina]
