Three tools in one small extension

Table Extractor

Hover any table on any webpage — a small "Extract table" badge appears. Click it, or use the popup's "Tables on page" tab, to get CSV, JSON, or Markdown instantly, plus XML, YAML, SQL, TSV, and TOML.

JSON Viewer

Navigate directly to a raw JSON API endpoint or .json file and the page auto-formats into a dark, collapsible, syntax-highlighted tree — the same idea as JSONView or JSON Formatter.

Quick Convert

Click the toolbar icon for a full mini-converter: paste, upload a file, or drag & drop, pick from/to across 34 text-based format pairs, and get your result without leaving the page.

Turn any HTML table into CSV, JSON, or Markdown

Most tables on the web — pricing pages, data reports, Wikipedia comparisons, admin dashboards — aren't offered as a download. The extension reads the table directly out of the page's HTML and converts it locally in your browser, so you can paste the data into a spreadsheet, a script, or anywhere else you actually need it, without manually copying and reformatting rows by hand.

Raw JSON pages, made readable

API responses and .json files often render as an unreadable wall of text in a plain browser tab. The extension detects when a page's entire response is JSON and replaces it with a properly indented, syntax-highlighted, collapsible tree — click any object or array to expand or collapse it, with expand-all/collapse-all controls and a one-click copy.

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. See the full privacy policy for exactly how the "Open in converter" handoff works and what is and isn't sent anywhere.

Install it

Not yet published to the Chrome Web Store or Firefox Add-ons — load it directly from source in the meantime. Full instructions (Chrome, Edge, Brave, and Firefox) are in the extension README on GitHub.
