JSON Formatter & Validator
Paste messy or minified JSON and get it back indented, sorted and validated: with the line and position of a syntax error whenever your browser reports one. Handles large payloads and never leaves your browser.
Watch explai answer one real business question
A recording of the product itself. At the top, the question someone types in: roll a promotion that grew revenue 12% out across all European stores. Below it, explai's answer: it checks that claim against the real sales data, shows every reasoning step, and comes back with a chart and a clear recommendation against the rollout. Under 10 seconds, starts by itself, nothing to click.
That was one question, on our data. In measured deployments teams save about three hours per person a day, and a week of repeatable analysis comes back in roughly five minutes. A private sandbox is waiting for your data: upload a CSV and ask your first question in a few minutes.
Questions people ask about this tool
How do I format JSON online?
Paste the JSON into the input pane and it is parsed and re-indented instantly. Formatting happens in your browser using the built-in JSON parser, so even large or confidential payloads are never uploaded.
Why does my JSON say "Unexpected token"?
That error means the parser hit a character it cannot use at that position: most often a trailing comma, a single quote instead of a double quote, or an unquoted key. The validator shows the offset so you can jump straight to the character that broke it.
Is it safe to paste production data into an online JSON formatter?
In this one, yes: it runs entirely client-side, makes no network request when you format, and stores nothing. That is not true of every online formatter, so check before pasting anything sensitive elsewhere.
