Make messy JSON readable in a single paste.
Paste any JSON payload and instantly format, validate, and minify it—without leaving your browser, opening an IDE, or searching for another tool.
JSON TOOL
Clean up payloads without leaving Kompi.
Paste API responses, webhook payloads, or config files and format, validate, and copy them in one place.
Raw JSON
Indentation
Formatted JSON
// Output will appear here once your JSON is valid and formatted.
Formatting runs in your browser. Nothing is sent to Kompi servers.
JSON, BUT LESS CHAOTIC
Built for devs, operators, and curious teammates.
API RESPONSES
Inspect payloads quickly
Paste responses from your API client and read them like a human instead of a wall of characters.
WEBHOOKS & LOGS
Untangle noisy log lines
Format production logs or webhook payloads before you drop them into tickets, docs, or DMs.
CONFIG & SETTINGS
Safer edits for config files
Pretty-print config, make changes, then minify again before you paste it back into your app or dashboard.
Questions about the JSON formatter?
Here's how this tool fits into your Kompi workflow alongside links, QR codes, and contact forms.
Is the Kompi JSON formatter free?
Yes. The JSON formatter is free to use with no login or signup required.
Is my JSON sent to Kompi servers?
No. Formatting happens in your browser. Kompi does not store or inspect the JSON you paste into this tool.
What can I use this formatter for?
It works well for API responses, request bodies, webhook payloads, log snippets, and configuration files.
Can I use this inside my Kompi dashboard?
Yes. When you create a free Kompi account you can pin the JSON formatter as a dashboard tool so it’s always one click away.
Does it support big JSON payloads?
Yes, for most practical use cases. Extremely large payloads may be slow depending on your device and browser.
