Formatted JSON

FAQ

Pasted string looks like JSON but fails?

Leading BOM characters, smart quotes from Slack, or trailing commas from relaxed parsers break strict `JSON.parse`. Sanitize in a plain editor first.

Eval vs parse?

Never `eval` untrusted “JSON-looking” strings—use `JSON.parse` semantics only. Eval opens arbitrary code execution.

Escaped newlines?

Literal ` ` inside a JSON string differs from actual newlines; the parser handles escape sequences uniformly.

Large payloads?

Huge strings block the main thread; sample-truncate debugging is faster than pasting entire production blobs.

Schema validation?

Parse success ≠ business correctness; enforce contracts separately.

Privacy?

Local-only parsing in your browser.
