Question 1

How do I convert an HTML table to CSV?

Accepted Answer

Paste the HTML markup that contains one or more <table> elements into the input area, pick a delimiter and click Convert. The tool parses the DOM, extracts every table and lets you preview and download each one as CSV, TSV or Excel-ready XLS.

Question 2

Does it handle colspan and rowspan?

Accepted Answer

Yes. The parser expands colspans and rowspans into a clean rectangular grid, repeating each cell value across the spanned cells so the resulting CSV opens correctly in Excel, Sheets or pandas without gaps.

Question 3

What if the HTML has multiple tables?

Accepted Answer

Each table gets its own tab in the preview. Use the Table 1 / Table 2 / ... buttons to switch between them, then download whichever table you need. You can also re-emit all tables as one CSV file separated by blank lines.

Question 4

Is my HTML sent to a server?

Accepted Answer

No. Parsing happens in your browser using the built-in DOMParser. No markup, table data or extracted CSV is uploaded anywhere.
