Add class gives the a class attribute so you can target it from your own stylesheet, for example table.csv-table td { padding: 8px }. Inline styles writes border and padding rules directly onto the table and cells, which is what you want when pasting into Gmail, Notion, or a CMS that strips external CSS. You can enable either, both, or neither."}},{"@type":"Question","name":"How does it handle a field with a comma inside it?","acceptedAnswer":{"@type":"Answer","text":"Wrap the field in double quotes in your CSV and the comma stays part of the value. The line 「Smith, John」,42 parses into exactly two cells: Smith, John and 42, not three. Doubled quotes 「」 inside a quoted field become a single literal quote, and a newline inside the quotes is preserved, all following the RFC 4180 rule that most spreadsheets export."}},{"@type":"Question","name":"Does my CSV ever get uploaded to a server?","acceptedAnswer":{"@type":"Answer","text":"No. The parser and the HTML generator are JavaScript that runs entirely inside your browser tab, so the CSV you paste never travels over the network.

That means a financial export or a customer list with 5,000 rows stays on your machine, and you can even use the tool offline once the page has loaded."}}]}

Every cell is HTML-escaped, so a value like <script> shows as text, never runs. Inline styles survive a paste into Gmail or a CMS; the class hook keeps the markup themeable.

What this tool does

CSV to HTML Table converts a spreadsheet export, a database dump, or a pasted block of comma-separated rows into a ready-to-ship HTML <table>. The parser follows RFC 4180, so a cell wrapped in quotes keeps its embedded commas, its escaped "" quotes, and even a line break inside the field. Turn the first row into <thead><th> with one toggle, switch the delimiter to semicolon, tab, or pipe when your export is not comma-based, and decide whether the markup carries a class hook for your own stylesheet or basic inline borders that survive a paste into Gmail or a CMS. Every cell is HTML-escaped, so a value like <script> shows up as text instead of running. You see the rendered table and the source side by side, copy it with one click, and the whole thing runs locally without an upload.

How CSV to HTML Table fits into your work

Use it when the main problem is getting content from one practical format into another.

Conversion jobs

  • Turning pasted content or local files into a handoff-friendly format.
  • Previewing a conversion before you use it in a larger workflow.
  • Cleaning small format mismatches without opening a full editor.

Conversion checks

  • Try a small sample first when the source format is messy.
  • Check character encoding, separators, and line endings after conversion.
  • Keep the source until the converted output has been reviewed.

Real-world use cases

  • Drop a data table into a CMS post

    You wrote a blog post in a CMS that only takes HTML, and you have the numbers sitting in a spreadsheet. Export the range as CSV, paste it here, turn on the header toggle, switch on inline styles so the borders survive the editor, and copy the markup straight into the body. No external stylesheet to wire up, no hand-typing forty <td> tags.

  • Render a quick report in an HTML email

    Support hands you a CSV of last week's ticket counts and you need it inside a status email. Email clients strip <style> blocks, so you flip on inline styles, paste the CSV, and the table arrives with borders and padding baked into each cell. It looks the same in Gmail, Outlook, and Apple Mail because nothing depends on external CSS.

  • Generate table fixtures for tests or docs

    A developer needs a sample <table> for a component story or a documentation snippet. Type a few CSV rows, choose the class option so the markup stays clean and themeable, and copy the result into the codebase. The output is plain semantic HTML with <thead>, <tbody>, and escaped cells, ready to paste without a formatter pass.

  • Convert a semicolon export from a European spreadsheet

    Spreadsheets in many locales export with a semicolon delimiter because the comma is the decimal separator. Switch the delimiter to semicolon, paste the file, and the tool splits the columns correctly instead of mashing everything into one cell. The same works for tab-separated copies pasted out of Excel.

Common pitfalls

  • Leaving the header toggle on when the CSV has no header line. The first real data row gets promoted into bold <th> cells and disappears from the body. If line one is already data, turn the toggle off so every row stays a normal <td> row.

  • Picking the wrong delimiter for the export. A semicolon or tab file parsed as comma-separated lands every line in a single cell. Check the raw text first and switch the delimiter to match the character that actually separates the columns.

  • Expecting raw HTML in a cell to render. Cell content is escaped on purpose, so <b>bold</b> shows the literal tags as text, not bold styling. The escaping is a safety feature against injection. To build a styled table from scratch instead, use the HTML Table Generator.

Privacy

Parsing and HTML generation are plain JavaScript running in your browser tab. The CSV you paste, the table you preview, and the markup you copy never leave the page, and nothing is logged. There is no shared-link caveat here either: the input is not written into the URL, so even a long export stays entirely local to your session.
