A JSON Editor Online Alternative: VadeKit JSON Formatter

Looking for a JSON Editor Online alternative that doesn't paste your data through a web form? JSON Editor Online's free tier is ad-supported; removing ads and adding private cloud storage requires a subscription. VadeKit's JSON Formatter pretty-prints, minifies and validates JSON, walks it as a collapsible tree, and flips a nested array into a flat table - entirely on your device, included in the same $24 as every other tool.

For a quick, non-sensitive JSON check, JSON Editor Online’s free web tool is fine. If the JSON contains anything sensitive - API keys, user data, internal config - or you just don’t want ads, VadeKit’s JSON Formatter does the same job locally, included in the one-time $24.
