Convert CSV to HTML, free in your browser

Convert CSV or TSV rows into a responsive HTML table. Cell values are escaped so data displays as text rather than being interpreted as HTML.

How to convert CSV to HTML

1. Choose a CSV or TSV file.
2. Choose whether the first row contains column names.
3. Convert and download the standalone HTML table.

Limits & good to know

• CSV and TSV files up to 50 MB are processed on your device.
• The first row is treated as column names by default.
• The output is a static table and does not include sorting, filtering, or interactive scripts.

Frequently asked questions

Are my files uploaded to a server?

Your files are processed on your device, not uploaded to our servers. Your file and edits are saved in this browser for recovery, and previous documents remain in Saved drafts when you open another file. Use Saved drafts to resume or delete individual copies, or clear this site’s browser data to remove all copies. Browser storage can be cleared or become unavailable; download important work.

Can cell values run HTML or scripts?

No. Cell content is escaped before it is inserted into the generated table.

Is this really free, or free "until you hit a limit"?

Really free. Unlike most "free" PDF sites there is no task-per-day cap, no locked Pro features, no watermark stamped on your file, and no payment step before download. Every tool is the full tool.
