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.
