About this Tool
Use this HTML Table to CSV Converter to extract clean comma-separated data from table markup. The parser recognizes table rows, header cells, body cells, captions where useful, and simple row or column spans with clear warnings when the layout cannot be flattened neatly. It is best for real table structures rather than visual layouts built with unrelated markup.
Examples
- <table> <thead><tr><th>City</th><th>Quarter</th><th>Revenue</th></tr></thead> <tbody> <tr><td>Berlin</td><td>Q1</td><td>12800</td></tr> <tr><td>Paris</td><td>Q1</td><td>11450</td></tr> </tbody> </table>
Frequently Asked Questions
Is my HTML table markup uploaded to a server?
No. The tool parses, transforms, previews, and exports data locally in your browser without uploading your input.
Does it extract tables from any web page?
The tool works with pasted markup or local files in the browser. It does not fetch pages from the network.
How are colspan and rowspan handled?
Simple spans can be expanded into repeated or empty cells, but complex layouts should be flagged for review before CSV export.
Is HTML output escaped?
Yes. Text values are escaped before generating table markup so cell contents do not accidentally become active HTML.
What file sizes are practical in the browser?
Small and medium tables are the best fit. Very large files can use a lot of memory because parsing, previews, and exported results all live inside the browser tab.
