# JSON-LD Validator

> Paste JSON-LD to validate structure, detect missing required fields, format code, and identify schema errors before deployment.

**Category:** Schema

## How it works

The JSON-LD Validator runs directly against a live URL or your own pasted content — no signup, no install. Results come back in seconds as a prioritized, plain-English list rather than a raw score, so you know exactly what to fix first and why it matters. It's a focused, single-purpose check, built to answer this one question quickly rather than replace a full schema audit.

1. Paste in your URL, text, or data — no signup required.
2. The tool runs its analysis and returns results in seconds.
3. Review the flagged issues, ranked by severity, with a plain-English explanation of each.
4. Fix the highest-priority items first, then re-run to confirm.

**Why it matters:** Structured data is how search engines and AI answer engines understand what a page actually is, not just what it says. Valid JSON-LD is table stakes for rich results in Google Search and for being cited accurately by AI Overviews, ChatGPT, and Perplexity.

This is a free, interactive, browser-based tool — no signup required. It runs client-side JavaScript, so this Markdown page describes what it does; [use the live tool](https://iliassami.com/tools/json-ld-validator) to actually run it.
