Hi HN,

I made a browser addon called Website Table Exporter for Firefox and Chrome. It lets you export any HTML table on a page to CSV, JSON and Markdown, straight to your clipboard with one click.

Why?

Because copying tables from websites is surprisingly annoying. I kept running into mangled formatting or weird extra markup when trying to grab data for research or personal use. So I built something small, open, and fully client-side. No tracking, no network calls, no nonsense.

Features:

- Export any HTML table to CSV, JSON or Markdown.

- One-click export via a small button in the first cell of each table.

- Automatically strips inner HTML tags.

- Warns if the table has merged cells (which can mess up the output).

- 100% local, no telemetry, no ads.

How to use it:

Install the addon, visit any page with a table, and click the little button that appears in the top-left cell. You can toggle the export buttons visibility clicking the addon button on browser's top bar.

Would love any feedback, ideas, or bug reports. Thanks!
