Question 1

What does JSON Utilities do?

Accepted Answer

It prettifies (formats with indentation) or minifies JSON, and converts JSON to and from CSV and YAML.

Question 2

Is my JSON data uploaded to a server?

Accepted Answer

No — all formatting and conversion happens locally in your browser, so you can safely paste API responses or config data containing sensitive values without them leaving your machine.

Question 3

Will any JSON convert cleanly to CSV?

Accepted Answer

CSV conversion works best on a flat array of objects with consistent keys; deeply nested or irregularly shaped JSON may not flatten cleanly into rows and columns.

Question 4

Does minifying my JSON change the actual data?

Accepted Answer

No, minifying only strips whitespace, line breaks, and indentation — the keys and values stay exactly the same, so it's a lossless operation.

Question 5

Is JSON Utilities free to use?

Accepted Answer

Yes, it's free with no account or sign-up required.
