What HTML table formats are supported?

The converter supports standard HTML tables with , , , , , and elements. It correctly handles tables with or without header rows, colspan/rowspan attributes are ignored gracefully, and special HTML entities are decoded automatically.

Is my data safe? Does it get uploaded anywhere?

Your data never leaves your browser. All parsing and conversion is done entirely client-side using JavaScript. No data is uploaded to any server, and nothing is stored or logged. This makes it safe to use with sensitive or proprietary data.

What is the difference between CSV, TSV, and JSON output?

CSV (Comma-Separated Values) separates fields with commas and is widely supported by Excel, Google Sheets, and databases. TSV (Tab-Separated Values) uses tabs instead of commas, which avoids quoting issues when data contains commas. JSON (JavaScript Object Notation) outputs an array of objects, ideal for use in APIs and web applications.

Can I convert multiple tables from a single HTML page?

Yes! If your HTML contains multiple elements, the tool detects all of them and lets you select which table to convert. A table selector appears when multiple tables are found.

What should I do if the conversion result looks wrong?

Make sure the HTML you paste includes a valid element. If your table uses complex nested structures, try simplifying it first. The tool handles most standard HTML tables correctly, but heavily customized layouts (e.g., tables used purely for layout) may not parse as expected.
