Frequently asked questions

What does the HTML output look like?

The output is a complete HTML table with a <thead> containing column headers and a <tbody> with one <tr> per data row. Each cell uses <th> for headers and <td> for data.

Can I style the HTML table?

The exported HTML includes basic inline styles. You can add your own CSS classes or styles after downloading.

Can I convert a large CSV to HTML?

Yes, there is no row limit. However, very large tables may be slow to render in a browser — consider filtering to the rows you actually need before exporting.

Is the CSV to HTML conversion free?

Yes, completely free. No account, no size limit, no paywall.

Can I use the HTML table in an email?

Yes. The semantic HTML table structure is compatible with most email clients. You may need to apply inline styles for full email client compatibility.
