JSON mistakes are rarely dramatic. More often they are small syntax slips that waste time because they break silently somewhere downstream.
Use pretty mode for reading
Pretty formatting helps when you need to:
- inspect nesting
- compare fields
- spot duplicated keys or misplaced arrays
- debug payload shape before sending a request
Use compact mode for transport
Compact output is useful when:
- you need to paste payloads into tight config fields
- size matters in logs or quick sharing
- you want a clean one-line output for documentation snippets
Text
{"user":{"id":42,"role":"admin"},"flags":["beta","staff"]}JSON review pass
- Validate the payload before copying it anywhere important.
- Switch to pretty mode when the structure feels hard to scan.
- Use compact mode only after the payload is already correct.
- Never assume comments are valid in strict JSON.
