Reads the JSON above. Nested objects are named <Root>_<field> (e.g. Root_tracks); arrays use T[] style. Numeric fields are distinguished as int64 / float64. Python nested objects are flattened to dict; TypeScript expands them fully.
JSON Format: Beautify / Validate / Minify
Typical scenarios: ① format compact JSON returned by an API into readable text; ② check whether JSON is valid (commas, quotes, brackets) before writing code; ③ remove whitespace before deploying a config file.
How to use: paste your JSON, then click Beautify to indent, Minify to strip whitespace, or Validate to check legality. On error, the tool points to the exact line and position.
Notes: ① watch for leading/trailing spaces or invisible characters when pasting — they may break parsing; ② the standard format doesn't allow NaN/Infinity and will flag them in red; ③ you can paste multiple JSON snippets at once.
