JSON Workbench

View, format, decode, compare, and save JSON locally in Chrome.

JSON Workbench is a private JSON workspace for Chrome. It helps you view, format, validate, decode, compare, and save JSON directly in your browser. Use it to inspect API responses, debug webhook payloads, compare old and new JSON, clean up copied JSON, and reopen previous JSON snippets from your local library. Core features: • View JSON in a clean workbench Open detected JSON responses in a full-page workbench designed for large payloads and easier navigation. • Format, minify, and sort JSON Pretty-print JSON, minify it, sort object keys, and customize indentation with 2 spaces, 4 spaces, or tabs. • Compare JSON for free Quickly compare current JSON with pasted JSON, saved JSON, recent JSON, or clipboard JSON when supported. See added, removed, and changed fields with clear paths. • Decode stringified JSON Detect escaped JSON strings such as webhook bodies, log fields, and API payloads, then decode them into readable JSON. • Save and reopen JSON locally Keep recent JSON and manually saved JSON in a local library. Rename, pin, reopen, delete, or compare saved items later. • Validate JSON with clear errors Check whether JSON is valid and see helpful error messages when something is wrong. • Side panel quick tools Paste JSON into the side panel for quick formatting, validation, decoding, copying, or opening in the full workbench. • Privacy-first local workflow JSON Workbench is designed to process JSON locally in your browser. Your JSON is not uploaded to a server. You can clear recent history, saved JSON, settings, or all local data anytime. Useful for: • Frontend developers inspecting API responses • Backend developers debugging payload changes • QA testers comparing expected and actual responses • Support teams reviewing error payloads and webhook data • Anyone who works with JSON and wants a faster browser-based workflow JSON Workbench is built for one purpose: helping you work with JSON faster and more privately in Chrome.
