Example input

{"customer":{"id":42,"active":true}}

Expected output

{
  "customer": { "id": 42, "active": true }
}

Reproducible method

  1. Preserve the original and create the smallest representative sample.
  2. Run a strict parse or validation before transformation.
  3. Record options, compare counts and structure, then test in the receiving system.

Common error

Trailing commas and single quotes are JavaScript conventions, not valid JSON.

Reduce a failure while retaining the problematic structure; this separates malformed input from unsupported behavior.

Technical limitation

Formatting cannot repair truncated input or guarantee safe integer precision.

A successful preview does not remove format ambiguity or downstream requirements.

Security and privacy

Redact credentials and compare the parsed structure after formatting.

Local processing reduces transfer risk but cannot protect a compromised browser, unsafe extensions, clipboard history, or later misuse.
