Tool HTML table extractor — Extract tables from pasted content and convert them to multiple formats. Paste HTML, rich text, or plain text containing tables, and the tool automatically detects and displays each table with a preview, then allows you to export it as HTML, Markdown, CSV, TSV, or JSON.

Yet another in my growing collection of paste-conversion tools. This one accepts pasted rich text from browsers (with embedded HTML tables) and converts every detected table into HTML, Markdown, CSV, TSV, or JSON.

Try it out by selecting everything on the Wikipedia List of cities and towns in the San Francisco Bay Area page and pasting it directly into the tool:

Screenshot of a web interface for converting table data between formats. A row of tabs labeled HTML, Markdown, CSV, TSV, and JSON sits below the bottom edge of a styled data table, with the TSV tab currently selected. The TSV tab displays the table's contents as tab-separated plain text in a monospaced font inside a bordered panel, with a "Copy" button in the upper right of that panel.

On a similar note, I recently rebuilt my Rich text to markdown tool to add support for tables and generally improve the UI.
