How do you inspect large JSON API responses during development?

When working with APIs, I often need to inspect and debug JSON responses, especially when the payload is large or deeply nested.

Typical tasks include:
• formatting JSON to make it readable
• validating JSON payloads
• comparing two API responses
• checking payload size for performance
• converting JSON to CSV or other formats

I’m curious what tools other developers are using for this.

Do you rely on Postman extensions, browser tools, or online utilities?

Recently I started using a browser-based JSON toolkit that helped with formatting and payload analysis:

Would love to hear what tools or workflows others prefer when dealing with JSON-heavy APIs.
