Hi Product Hunt! 👋 I built JoinJSON to make everyday JSON tasks easier for developers. Merging files, working with nested objects, and reviewing JSON changes can take extra time when switching between different tools. With JoinJSON, I want to make these tasks simpler and more convenient in one place. I'd love to hear your feedback!
