A small workbench for everyday JSON.

JSON Workbench helps developers and anyone working with structured data inspect, validate, and tidy JSON without creating an account.

What it does

Format with two spaces, four spaces, or tabs; remove optional whitespace; sort object keys; and copy or download the result. The guides explain common mistakes with working examples.

How it works

Parsing and formatting happen in your browser using JavaScript. This is a syntax tool, not a JSON Schema validator. It does not verify business rules or whether an API request is correct.

Our approach

Keep the original input visible, report errors without inventing repairs, and explain limitations plainly. No JSON history is saved.
