Frequently Asked Questions

What file formats does the HTML Table Generator support?

The HTML Table Generator supports multiple input formats including CSV (Comma-Separated Values), TSV (Tab-Separated Values), JSON (JavaScript Object Notation), and manual entry. You can paste data directly or upload files in these formats.

Can I customize the styling of the generated HTML tables?

Yes! The tool offers flexible styling options. You can choose to include CSS classes, inline styles, or both. When using inline styles, you can customize border width, border style, border color, and header background color to match your design requirements.

Does the tool handle special characters and HTML entities?

Yes, the HTML Table Generator automatically escapes special characters to prevent HTML injection and ensure proper display. All cell values are properly escaped, including quotes, angle brackets, ampersands, and other HTML entities.

Can I use the first row as table headers?

Yes, when using CSV/TSV input, you can enable the "Use first row as header" option. This will convert the first row into HTML table headers using <th> elements instead of regular table cells. In manual entry mode, the first row is automatically treated as headers.

Can I create tables manually without importing data?
