Secure JSON Repair
Format & repair JSON — 100% offline, no server
Secure JSON Repair launched on March 17, 2026.
What it does
I built this because I was tired of pasting API secrets into random online JSON formatters. Everything runs 100% locally in your browser. Zero server calls. Turn off your WiFi and it still works perfectly. Key features: - Auto-Repair — fixes trailing commas, unquoted keys, single quotes automatically - Collapsible Tree View with Copy Node Path - Sort Keys A→Z recursively - Syntax highlighting — One Dark Pro theme - Light & Dark mode - 100% free, no ads, no tracking
The only JSON formatter that never sends your data to a server. Built for developers who handle sensitive, private, or confidential data. Auto-repair broken JSON, explore with tree view, works 100% offline. Forever free.
Are You Sure Your JSON Formatter Isn't Logging Your Data? Think about the last time you pasted JSON into an online formatter. Was there an API key in it? A database response? A user record? An auth token? Most developers never think twice about this — and that's exactly what makes it dangerous. Secure JSON Repair was built for one reason: to give developers a professional JSON tool that never touches a server . Every single operation — formatting, validation, auto-repair, tree rendering — happens entirely inside your browser using local JavaScript. There is no server. There are no logs. There is no way your data can leak. One accidental paste of a production API response into the wrong tool…from secure-json-repair.netlify.app

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
