What is a CSV file?
CSV – Comma-separated values. CSV (comma-separated values) is plain text with one row of a table on each line and the cells separated by commas, semicolons or tabs. Every spreadsheet, database and programming language reads it, but it holds only values: no formulas, formatting or several sheets.
CSV Converter →What is an HTML file?
HTML – HTML page. HTML is the language of web pages. A saved .html file holds the text and structure of a page and shows in any browser.

Good to know
- The separator (comma, semicolon, tab or pipe) and the text encoding are detected, so files saved by spreadsheet programs in other countries open correctly. Numbers and dates are recognised; leading zeros in numbers are dropped.
- Every sheet is in the one HTML file, with its pictures built into it.
Frequently asked questions
Is converting CSV to HTML free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my CSV files uploaded anywhere?
This conversion runs on our server, because reading a CSV file needs LibreOffice, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the CSV file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the HTML look the same as the CSV?
The text and structure are kept: headings, lists, tables, bold and italic. Exact page layout, fonts and spacing may differ, because HTML is flowing text, not fixed pages.
Can I convert several CSV files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
