Inputs used

  • Input accepts JSON, CSV, and YAML (for YAML→JSON action)
  • JSON Patch Diff compares source JSON against target JSON panel
  • Conversion actions infer primitive value types where possible

Formula basis

  • Validation uses strict JSON.parse behavior
  • Sort keys uses recursive lexicographic ordering
  • Flatten/unflatten use dot notation with [index] for arrays
  • JSON Patch Diff outputs add/remove/replace operations compatible with RFC6902

Assumptions and limits

  • CSV parser assumes first row is header
  • YAML parser supports common indentation-based YAML structures
  • Unflatten expects object keys in dot/bracket path format
  • Large payloads may be slower on low-memory devices
