Stop copying JSON into random websites. Pretty Payload gives you clean, secure JSON inspection in one click. View, format, repair, and explore any payload with everything running 100% locally. Nothing you inspect ever leaves your computer. Whether you're debugging APIs, inspecting network responses, reviewing webhook payloads, or working with copied JSON, Pretty Payload turns unreadable data into something you can actually work with. Why Pretty Payload? Most online JSON formatters require you to paste sensitive data into a website. That might be fine for sample data, but it's not ideal when you're working with customer information, PHI (protected health information), production payloads, authentication tokens, internal APIs, or proprietary business data. Pretty Payload works entirely inside your browser. • No uploads - your JSON is processed entirely on your machine • No cloud processing • Nothing you inspect is ever stored or shared • Works offline Your data stays where it belongs: on your computer. ⚡ Features ✓ Format JSON instantly Beautify compact or minified JSON into an easy-to-read, syntax-highlighted view. ✓ Repair malformed JSON Automatically fixes common syntax issues so you can spend less time debugging formatting problems. ✓ Un-stringify nested JSON Automatically detects JSON stored as strings and converts it into readable, expandable objects. ✓ Search everything Find keys, values, IDs, error messages, or any text inside your payload. ✓ Sort alphabetically Organize object properties to make large payloads easier to compare and navigate. ✓ Trim payloads Remove keys you don't need, with full undo, then copy the cleaned JSON. ✓ Import from your clipboard Paste JSON from Postman, logs, browser dev tools, Slack, emails, or documentation. ✓ Read JSON directly from webpages Inspect payloads without the copy-and-paste workflow. 🔒 Privacy First Pretty Payload processes everything locally.
