I’m creating an JSON developer toolkit app — need help deciding which tools to implement next

Hi everyone

I’ve been working on a side project: an online developer toolkit focused on JSON and data handling. Right now, I’ve already implemented:

-JSON Formatter & Validator with AI

-JSON ⇆ CSV and JSON ⇆ Excel converters

-JSON ⇆ XML converter and YAML ⇆ JSON converter

-JSON Minifier & Beautifier

-JSON Compare & Schema Generator

-AI JSON Generator (turn plain English into valid JSON)

-Mock API creator (publish JSON as a temporary API endpoint)

-JSON filter and JSON Merge

-JSON visualizer and JSON Translator

-JSON to Html and JSON to TS

-JSON to String

-SQL Formatter

My challenge is figuring out what features would be most useful to add next?

If you’ve used similar toolkits before, what features did you find missing?

I’d love to get feedback from other developers so I can prioritize the roadmap better.

Thanks in advance for sharing your thoughts
