Convert CSV into an HTML table
Need your data on a web page? This tool does the convert csv to html table job: it reads your CSV and generates semantic <table> markup with rows and cells you can paste directly into a site, a CMS or an HTML email.
Mark the first row as a header and it is wrapped in a <thead> with <th> cells; the rest goes in a <tbody>. Special characters are safely escaped, so values containing <, > or & render correctly instead of breaking your page.
Want the data as a spreadsheet instead? Use text to CSV or CSV からテキストへ. For APIs, see JSON から CSV へ.
How to use it
貼り付けまたはアップロード
Add your text or drop a file — it is read locally in your browser, never uploaded.
Preview & adjust
Check the live table and the row / column counts, then tweak the delimiter or options if a column looks off.
Copy or download
Grab the result with Copy or Download. You can reopen recent conversions from this device too.

Header rows with <th>
With 1 行目はヘッダー ticked, your column titles become <th> cells inside a <thead>. That is better for accessibility and lets screen readers and CSS target headings separately from data.
Safe escaping
Any value containing <, > or & is escaped to its HTML entity, so the table displays the literal text and never injects unintended markup. This keeps the output safe to drop into a page.
Styling the table
The markup is intentionally minimal — no inline styles — so you can apply your own CSS classes or a framework. Add borders, striping and padding in your stylesheet to match your site.
Copy and paste workflow
Use the Copy button to grab the markup, then paste it into your HTML. Because everything runs locally, you can convert sensitive data without sending it anywhere.
Tips and edge cases
- Tick the header option for accessible, styleable headings.
- Add your own CSS class to the <table> after pasting to control its look.
- For data exchange rather than display, export CSV, TSV or JSON instead.
From data to a web page
Pasting CSV into a page by hand is error-prone; generating the markup keeps every row and cell consistent. The output works in static sites, CMS editors, documentation and HTML email, and because it carries no inline styles it inherits your existing table CSS. For very large datasets, consider paginating or lazy-loading the table in your own template rather than rendering thousands of rows at once.
