Examples & Use Cases

  • Before:

    Retyping the structure by hand for each language, and quietly introducing a typo in a key name that only shows up when a test fails much later.

  • After:

    Paste it once, click through the output formats, and copy each version out. The structure and every key stays identical because they all come from the same parse.

Useful when the same payload has to be kept in step across a polyglot codebase.

Move a payload between two services
The same object often has to exist in more than one language: a fixture in the Python test suite, a literal in the PHP client, a JSON body in the API docs.
  • Before:

    A single-line dict or array from a log file, full of single quotes and language keywords, that no JSON viewer will accept.

  • After:

    Indented JSON you can actually read, with the nesting visible and the keys in the order they were logged.

Turns whatever your logs printed into something you can inspect.

Read an object printed in a log
Logs and consoles print objects in their own language's syntax, which is rarely valid JSON and rarely readable when it is one long line.

Frequently Asked Questions

JSON, a JavaScript object literal, a Python dict, a PHP array (short [] syntax) or a Ruby hash. Each output uses that language's own conventions - 4-space indents for Python and PHP, 2 for the rest, bare keys in JavaScript where they are valid identifiers, and the right spelling for null, true and false.
