The Free CSV to HTML Converter With Live Preview

Sometimes you have data in a spreadsheet or CSV file but you need an HTML table: dropping data into a web page, an email newsletter, a CMS, or any document that accepts HTML. Our free online CSV to HTML converter does exactly that: paste your CSV, see a live preview of the table, and copy or download clean HTML source. Everything runs locally in your browser, so your data is never uploaded and never logged.

Your CSV is never sent to our servers. All conversion happens in JavaScript on your device. We log nothing. Free forever with no account required.

Auto-Detect Delimiter

Not sure if your file is comma, semicolon, tab, or pipe separated? Leave the delimiter on Auto and the converter figures it out using a robust CSV parser. You can also force a specific delimiter, which is handy for European CSV files that use semicolons or for tab-separated exports.

Clean, Semantic HTML Tables

  • Header row: the first row becomes <thead> with <th> cells, or generated headings if your data has none
  • Custom class: add your own CSS class to the <table> so it matches your site styles
  • Inline borders: optionally add inline border styles so the table renders standalone in emails and documents without external CSS
  • Pretty or minified: readable indented HTML, or compact single-line output
  • Safe output: all cell content is HTML-escaped so special characters cannot break your markup

Live Preview and HTML Source

Switch between a live rendered preview of your table and the copy-ready HTML source at any time. The preview shows exactly how the table is structured, while the source view gives you clean, escaped HTML you can paste straight into your page.

Frequently Asked Questions

Is the CSV to HTML converter free?
Yes, completely free, forever. Conversion, delimiter detection, header and class options, inline borders, live preview, copy, and download are all available with no account, no subscription, and no usage limits.
Is my CSV data sent to a server?
No. All conversion runs locally in your browser using JavaScript. Your data is never transmitted to our servers and we keep zero logs.
Does it auto-detect the delimiter?
Yes. Leave the delimiter set to Auto and the parser detects comma, semicolon, tab, or pipe separated values automatically. You can also force a specific delimiter if your data is ambiguous.
Can I add my own CSS class to the table?
Yes. Set a custom class in the Behaviour settings and it is added to the <table> element so the output matches your site styles.
Will the table render in an email?
Turn on inline borders and the converter adds inline border styles to the table cells, so it renders correctly in email clients and standalone documents that do not load external CSS.
Is the cell content safe / escaped?
Yes. All cell content is HTML-escaped, so characters like angle brackets and ampersands cannot break your markup or inject unwanted HTML.
