Parsefy

What it does

Parsefy is a set of browser-only converters for JSON, CSV, Excel and markdown tables. Paste an API response or drop ajson file and get clean, spreadsheet-ready output — nested objects become dot-notation columns, and records with different keys merge into one header row instead of dropping fields. Nothing is uploaded. Everything runs in your own tab, so it's safe for production data and client exports. No account, no file-size limits, works offline.

Free online JSON to CSV converter. Turn JSON arrays and API responses into spreadsheet-ready CSV in your browser — no upload, no sign-up.

Convert JSON arrays and API responses into clean, spreadsheet-ready CSV — entirely inside your browser. Drop one or more .json files into the editor, or paste an array of objects straight from an API response. Nothing is transmitted anywhere. Nested objects become dot-notation columns such as user.address.city. Choose Multiple output and repeated arrays are split into their own related tables instead. Take the result as a single CSV file, or as a ZIP of related tables when you split arrays — ready for Excel, Google Sheets or a database import. Everything runs in your browser tab — there is no upload step and no server to store anything. That makes it safe for API responses, database dumps…from parsefy.app

  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…
