Transmify

Extract tables from webpages, auto-format raw JSON, and convert 34+ data formats — free, right from your toolbar.

Transmify extracts tables from any webpage, turns raw JSON pages into a readable viewer, and converts 34+ data formats — all free, with no signup and no account. WHAT IT DOES 📊 Table Extractor Hover any table on any webpage and a small "Extract table" badge appears. Click it — or open the popup's "Tables on page" tab to see every table found with a one-click Extract button — to get the table instantly in whichever structured format you need. 🔍 JSON Viewer Navigate to a raw JSON API endpoint or a .json file and the page automatically reformats into a dark, collapsible, syntax-highlighted tree instead of an unreadable wall of text. Expand or collapse any object or array, with expand-all/collapse-all controls and one-click copy. ⚡ Quick Convert Click the toolbar icon for a full mini-converter. Paste data, upload a file, or drag & drop, pick your source and target format from 34 text-based conversion pairs, and get your result without leaving the page you're on. Right-click any selected text for a "Convert selection" option too, which opens the full converter with your selection pre-filled and the format auto-detected. WHY INSTALL IT Most tables on the web — pricing pages, data reports, comparison tables, admin dashboards — aren't offered as a download. Copying and reformatting them by hand is slow and error-prone. Transmify reads the table directly from the page and converts it locally in your browser. Raw JSON API responses are common for developers, but browsers show them as flat, hard-to-read text. Transmify formats them automatically, the same idea as JSONView or JSON Formatter. And when you just need a quick format conversion, the toolbar popup means you don't need to leave your current tab to get it. PRIVACY The extension runs locally and only reads a table's content when you take a specific action — clicking "Extract," or navigating to a page the JSON viewer activates on. It doesn't scan or transmit page content automatically in the background. Full details at transmify.dev/privacy/.
