MyJSONPal

What it does

Legacy JSON formatters lag, crash on syntax errors, and force you to paste sensitive production data onto remote servers. MyJSONPal modernizes your workflow: ⚡ Magic Auto-Repair: Fixes trailing commas, single quotes, unquoted keys, and Python booleans in 1 click. 🔒 100% In-Browser Privacy: Zero network calls or logging. Process production payloads safely on your local machine. 🛡️ Type & Format Engine: Instantly generate Zod schemas, TypeScript interfaces, CSV, and YAML.

Format, validate, and auto-repair broken JSON instantly in your browser. 100% private client-side processing. Free developer JSON studio.

Prettify, validate and auto-repair JSON in your browser. Zero uploads, zero servers — every byte stays on your machine. MyJSONPal is a free online JSON formatter and validator built for developers who care about speed and privacy. Paste any JSON document into the editor and get a cleanly indented, color-highlighted result in milliseconds. Because everything runs in your browser through a Web Worker, your data is never transmitted, logged, or stored anywhere. Beyond pretty-printing, the workspace doubles as a strict validator: syntax errors are highlighted inline with line and column positions, and the Magic Auto-Repair engine can fix common mistakes such as trailing commas, single quotes,…from myjsonpal.com

  Talanoa▲346

  Hi 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…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
