Question 1

What is a JSON formatter?

Accepted Answer

A JSON formatter takes raw or minified JSON and re-indents it for readability. It also catches syntax errors like missing commas or unmatched brackets.

Question 2

Is my data sent to a server?

Accepted Answer

No. Everything runs in your browser. Nothing is uploaded or stored anywhere.

Question 3

What are collections?

Accepted Answer

Collections are named groups to organise your JSON files, similar to folders. You can create as many as you need.

Question 4

What is the difference between format and minify?

Accepted Answer

Format adds indentation for readability. Minify strips all whitespace to reduce payload size for APIs or storage.

Question 5

How do I validate JSON?

Accepted Answer

Click Validate in the toolbar. The error bar highlights syntax issues with a description of what went wrong and where.

Question 6

Can I download the formatted JSON?

Accepted Answer

Yes — use the Download button to save the current editor contents as a .json file to your device.

Question 7

Is there a file size limit?

Accepted Answer

There is no enforced size limit. Very large files may take a moment since everything runs locally in your browser.
