JSON formatter: demand and opportunity research
AltF Signals rates "json formatter" at 75 out of 100 on AltFTool's own editorial opportunity scale, against no sourced search-volume estimate and high competition. AltFTool ships this: the JSON Formatter pretty-prints and minifies JSON with a chosen indent, reports parser error messages for invalid input, and can turn URL query strings and form fields into JSON. It runs locally, does not repair broken JSON and does not send the GET or POST requests it previews.

JSON formatter: questions and answers
Is my JSON sent to a server?
No. Parsing and formatting use the browser's own JSON parser, so the data never leaves the page. That makes it reasonable for payloads you would not paste into an unknown online tool.
Does it fix invalid JSON?
No. It shows the parser's error message so you can find the problem, such as a trailing comma or single quotes, but it does not rewrite your input. Fix the reported spot and format again.
