Turns compact or minified JSON into a readable, indented document without changing the data.
The service parses JSON with json.loads, then re-serializes it with the chosen indent (0, 2, 4 spaces, or Tab), optional alphabetical key sorting, and optional ASCII escaping for non-Latin characters. The data itself doesn't change — only how it's written.
Turn on strict validation to require canonical JSON: double quotes, no trailing commas, no JS-style comments. On failure the error reports the exact line and column where parsing broke, taken straight from Python's json.JSONDecodeError.
