Johoba, thanks for the feedback. We noticed that there is a lack of tooling in this area, and want to build a better experience for you.

One of Wale IDE's features is to run your prompts over an CSV of data - see "Import data or start from scratch" on our landing page. Give this a try and see if it helps with testing your prompts.

Let us know if you would be open to a short 15 min call: link: https://cal.com/zach-zhao/20min?duration=20.
