Question 1

Can I format invalid JSON?

Accepted Answer

No — the formatter requires valid JSON. If your input is invalid, an error message will show you what went wrong and where.

Question 2

What does 'Sort Keys' do?

Accepted Answer

Sort Keys alphabetically orders all object keys in your JSON, including nested objects. This is useful for comparing two JSON objects or creating consistent output.

Question 3

Is my JSON data sent to a server?

Accepted Answer

No. All formatting and validation happens entirely in your browser. No data leaves your device.

Question 4

Can I load a JSON file from my computer?

Accepted Answer

Yes. Click the 'Load File' button to select a .json file from your device. The contents will be loaded into the input field.

Question 5

What indent options are available?

Accepted Answer

You can choose between 2 spaces, 4 spaces, or tab indentation. The selected indent style is applied when you click Format.
