Turn Excel Spreadsheets into Browser-Ready HTML Tables
Excel spreadsheets with pricing tables, comparison data, schedules, and reports need to be embedded in websites, emails, and online reports where installing Excel is not an option. XLSX-to-HTML converts your spreadsheet data into <table> HTML markup that renders natively in any browser, email client, or web page — no plugin, no download, no dependency.

Click "Convert Now" to open with XLSX → HTML pre-selected in the document tab.
Drag & drop your Excel file or click Browse. Works with .xlsx and .xls files.
Conversion runs entirely in your browser — no server upload, no cloud service involved.
Your clean HTML file downloads immediately, ready to paste into any CMS or email editor.
Excel Data to HTML Tables: Publish Spreadsheets on the Web
Spreadsheets and web pages are the two dominant data presentation formats in business, but moving data between them has always been awkward. Excel's "Save as Web Page" output is bloated with Microsoft-specific CSS and conditional comments that break in modern browsers. Copying and pasting into a CMS loses column alignment. XLSX-to-HTML produces clean, semantic <table> HTML that designers can style with standard CSS, CMS editors can paste directly, and email marketing tools can embed in HTML newsletters. Each Excel worksheet becomes a separate <table> element with <thead> for the header row and <tbody> for data rows. Cell values are HTML-escaped so special characters display correctly. The output HTML is framework-agnostic — paste it into WordPress, Webflow, HubSpot page builder, or any raw HTML editor. Developers building reporting dashboards use XLSX-to-HTML to render dynamic data tables without client-side JavaScript table libraries.

Key Questions About XLSX to HTML, Answered
Direct answers structured for AI extraction, voice search, and featured snippets.
Does the HTML output include styling, and are merged cells preserved?
The output uses semantic table, thead, tbody, tr, th, and td tags with minimal inline styles — you apply your own CSS to match your site's design. Merged cells in Excel produce colspan and rowspan attributes in the output HTML, visually preserving the merged appearance when rendered in a browser.
- Semantic markup: clean table/thead/tbody/tr/th/td structure
- Merged cells: become colspan/rowspan attributes automatically
- Styling: bring your own CSS — the structure accepts any table stylesheet
Are multiple worksheets handled in the output?
Each worksheet in the XLSX file becomes a separate table element in the output HTML, with the worksheet name as a preceding h2 heading. You can then extract individual tables from the HTML as needed.
- One table per worksheet, each with its own h2 heading
- Extract a single sheet's table by copying its section of the HTML
Does cell formatting like bold and colors carry over?
Basic cell formatting like bold is preserved as strong tags. Background colors can be included as inline style attributes. Complex Excel formatting — gradients, icons, sparklines — is not supported.
- Bold text: converts to <strong> tags
- Background colors: included as inline styles where present
- Gradients, icons, sparklines: not supported in the HTML output
Can I paste this HTML into WordPress or use it in an email?
Yes to both. In WordPress, switch to the HTML/Text block editor, paste the table markup, and your Excel data renders as a formatted table — make sure you're in code view, not the visual editor, when pasting. The output also uses table-based HTML layout, the standard for HTML emails, and is compatible with Gmail, Outlook, and Apple Mail. Add border-collapse: collapse and explicit border styles to make the table visible in email clients.
- WordPress: paste into the code/HTML view of the block editor
- Email clients: table-based layout works in Gmail, Outlook, Apple Mail
- Privacy: conversion happens in your browser — your spreadsheet never leaves your device
