Built Parsekit: free JSON tools that run entirely in your browser (nothing you paste is uploaded)

Got tired of JSON formatter sites that bury a simple tool behind popups and multi-step wizards, so I built a small collection of single-purpose ones:

• JSON Formatter & Validator (with clear error location)
• JSON to CSV and JSON to YAML converters
• Merge JSON Files (deep merge for objects, concat for arrays)
• JSON Diff, JSON Splitter, and JSON Escape/Unescape
• Base64 and URL encode/decode

Everything runs client-side: what you paste is processed in your browser and never uploaded. No signup either. The site uses Google Analytics for basic page-view and button-click counts, but it never sees what you paste.

Would love feedback, especially if something breaks on edge-case JSON, or if there's a tool you'd like next.
