Question 1

What is JSON?

Accepted Answer

A text format for objects and arrays. APIs and config files use it. Names stay in double quotes.

Question 2

Why format JSON?

Accepted Answer

Indent makes structure visible. That is the usual debug step for a one-line response.

Question 3

Why minify JSON?

Accepted Answer

To drop whitespace before you ship a payload. Values do not change.

Question 4

Does my JSON leave the browser?

Accepted Answer

No. Parse and print run in the tab.

Question 5

Can I pick the indent?

Accepted Answer

Yes. 2 spaces, 4 spaces, or a tab.

Question 6

What if the JSON is invalid?

Accepted Answer

The tool shows the error and where it is. Trailing commas and single quotes will fail.

Question 7

Can I format a file from disk?

Accepted Answer

Paste or drop the text. This is not a project-wide linter.

Question 8

Will this sort keys?

Accepted Answer

No. Order stays as parsed.

Question 9

JSON or YAML?

Accepted Answer

If the file uses YAML syntax, use the YAML page. This parser will reject it.

Question 10

Can I convert JSON to CSV here?

Accepted Answer

No. Use JSON to CSV for a table export.

Question 11

Is there a size limit?

Accepted Answer

A huge paste can stall the tab. Split the file if the browser freezes.
