About This Tool
Designed for API debugging and config file comparison, the JSON Diff tool normalizes both JSONs (optional key sorting and minification) and performs line- and word-level diff. It offers side-by-side and unified views with options to ignore whitespace and case, helping you quickly locate additions, deletions, and modifications. All processing is local to ensure privacy.
