I built a free JSON to CSV converter-what should I improve?

Hi Product Hunt community 👋

I recently built JSON to CSV Converter, a simple browser-based tool for turning JSON data into downloadable CSV files.

The goal was to make a common data task easier without requiring installation or an account.

You can:

• Paste or upload JSON

• Validate and format the JSON

• Preview the converted data in a table

• Copy or download the CSV

• Customize the delimiter

I’d appreciate feedback from developers, analysts, and anyone who works with structured data.

A few questions:

1. What feature would make this tool more useful in your workflow?

2. What should I improve first?

3. Are there any edge cases or JSON formats I should test?

You can try it here:

Thanks for sharing your thoughts!
