# JSON Validator

> Paste JSON and get instant pass/fail with the exact line and column of any syntax error.

Validate JSON free with live checking and exact line/column error location. Runs entirely in your browser - API payloads stay private.

- **Canonical:** https://www.ailovekit.com/dev/json-validator/
- **Category:** Developer Tools
- **Processing:** Runs entirely in your browser. Files are never uploaded to AiLoveKit servers.

## Find the Broken Bracket in Seconds

A single missing comma can break an entire deployment. AiLoveKit's **JSON validator** checks as you type, reports the parser error, and pinpoints the offending line and column with a code snippet - so you fix the problem instead of hunting for it. Because validation runs locally, it is safe to paste payloads containing keys, tokens, or personal data.

## What Gets Checked

- **Syntax** - trailing commas, unquoted keys, mismatched brackets and quotes.

- **Structure** - root type, key count, and array length on success.

- **Position** - error offset converted to line, column, and the failing line itself.

Need to pretty-print a valid payload afterwards? Use [JSON Formatter](https://www.ailovekit.com/dev/json-formatter/), or shrink it with [JSON Minifier](https://www.ailovekit.com/dev/json-minifier/).

## Frequently Asked Questions

**Does it show where the error is?**

Yes - the parser message plus the exact line and column, with the failing line shown underneath.

**Is my data sent anywhere?**

No. Validation runs in your browser tab, so secrets, tokens, and production payloads stay on your device.

**What JSON features are supported?**

Standard JSON (RFC 8259): objects, arrays, strings, numbers, booleans, and null. Comments are not valid JSON and will be flagged.
