JSON Formatter

Why format JSON before sharing it?

Clean JSON exposes missing commas, inconsistent casing, or unescaped characters that can silently break APIs. Paste payloads from Postman, mobile logs, or third-party webhooks, then hit Format to get a diff-friendly structure you can drop into GitHub issues, SEO audits, or knowledge base articles without extra tooling.

  • Use Validate before shipping schema changes to your production API gateway.
  • Minify responses embedded in HTML/JS to cut transfer size without changing data.
  • Share readable snippets with non-technical teammates—no IDE required.

Quick workflow

  1. Paste the raw JSON payload or response body.
  2. Click Format to beautify or Validate to catch syntax errors instantly.
  3. Copy the output and attach it to bug reports, API documentation, or templated metadata.

Tip: combine this with the API Tester to capture live responses, then format them here before publishing.
