Turn your JSON into a clean, readable table — right on your phone. Paste
in any JSON and it opens as a table you can scroll and scan. Nested
objects open inline. Arrays become rows. You can read a 500-line API
response in a few seconds without scrolling through walls of brackets.

If you've ever opened a JSON file on mobile and given up halfway, this
is the fix. Use it when you're testing an API on the train. Or
debugging a production response from your phone. Or reading someone's
config without firing up your laptop. Tap Sample on the first screen
if you want to see what the JSON Viewer looks like before pasting your
own.

The JSON tools, in more detail.

JSON Viewer. The main one. Paste raw JSON, get a table you can read
and scroll. Works on objects, arrays, and the deeply nested shapes
APIs like to return.

JSON Formatter. Prettify or minify any blob of JSON. Handy when an
API response is one long line and you want to make sense of it.

JSON Fixer. Catches the usual things that trip parsers: trailing
commas, single quotes, unquoted keys, stray comments. Pastes back
valid JSON.

String to JSON. If you copied JSON out of a log file and it's full
of backslashes and escaped quotes, paste it here to get the real
thing back.

JSON to CSV and CSV to JSON. For the times you want to drop a quick
result into a spreadsheet, or read someone's CSV without opening
Excel.

If you also work with XML.

XML Viewer. Same idea as the JSON Viewer. Paste your XML, see it as
a table you can read.

XML Formatter. Prettify or minify XML.

XML Fixer. Patches common XML syntax slips.

XML to CSV and CSV to XML. Quick conversions when you need them.

And if you live in YAML land.

YAML Viewer. Paste your YAML, see it as a table.

YAML Formatter. Clean up indentation and structure.

YAML Fixer. Patches small YAML syntax slips.

YAML to CSV and CSV to YAML. For the same spreadsheet moments.

Everything runs on your device. The JSON doesn't go to a server.
There's no sign-up, no account, nothing to log in to. It's free.
