How to use this developer tool

Paste JSON to validate it, pretty-print it for reading, or minify it for compact output without sending the content to Tool2Do.

How the processing works

  • Parses the JSON in your browser.
  • Reports syntax errors when parsing fails.
  • Outputs either indented JSON or compact minified JSON.

Example

Format a compact API response before comparing it with another payload.

Using the output

Use the output as a practical starting point, then review it before using it in an important workflow.

Assumptions and limitations

  • The JSON is not executed.
  • Large files may be easier to handle in a dedicated editor, but typical snippets and API payloads work well here.

Frequently asked questions

Does this require an account?

No. The core tool works without creating a Tool2Do account.

Is my input included in share links or analytics?

No. Tool2Do share actions use the tool page URL and safe metadata, not private values or uploaded files.
