Pretty-print or minify JSON while preserving its structure and values.

What you can use it for

Pretty-print or minify JSON while preserving its structure and values.

  • Formatted and minified nested JSON correctly through its anonymous API.
  • Tested outputs preserved arrays, booleans, Unicode and nested values.
Workflow coverage and comparison notes

Pretty-printing and minifying JSON only. API output was tested; native desktop integration and the other DevUtils utilities are outside this comparison.

Before you switch

Replaces the JSON formatting/minification slice of DevUtils, not its native macOS toolbox, offline integration or all 47+ utilities. Hands-on checks covered the API, not the browser UI. API requests leave your machine; client-side processing is a separate website claim. Anonymous API is rate-limited to 10 requests/minute. Terms prohibit using its API to build a competing clone. Paid API upgrades are optional.

Alternatives to these paid apps

Each comparison covers the workflow described above, rather than every paid feature.
