CodeKitHubJSON Tools
Format, validate and work with JSON data.
JSON is the data format behind almost every modern API, config file and log line — and it usually arrives minified into one unreadable line. These tools make JSON workable again, entirely in your browser: paste API responses, tokens and internal configs without them ever leaving your machine.
Which tool do I need?
- JSON Formatter — Make minified JSON readable, validate syntax with exact error positions, or minify it back for transport.
- Base64 Encoder / Decoder — API payloads and JWT segments often wrap JSON in Base64 — decode them first, then format.
- Text Diff — Compare two JSON responses or config versions line by line.
