Excel Data Trapped in Spreadsheets?

You have data in Excel that needs to go on a website. Maybe it's pricing tables, product specifications, research data, or schedules. Copying and pasting doesn't work-you lose formatting and structure. Manually coding HTML tables takes hours.

Converting XLSX files to HTML solves this instantly. Your spreadsheet becomes a clean HTML table that displays correctly in any browser. In our testing, even complex spreadsheets with merged cells and multiple columns convert accurately in seconds.

How to Convert XLSX to HTML

  1. Upload your XLSX file - Drag and drop or select your Excel spreadsheet
  2. Confirm HTML output - HTML is selected as your target format
  3. Download your HTML - Get clean table code ready for any website

The entire process takes seconds. No Excel installation required, no coding knowledge needed.

Why Convert Excel to HTML?

HTML tables are the standard for displaying structured data on the web. Here's why converting matters:

  • Universal compatibility - HTML works in every browser on every device
  • Clean code - Unlike Excel's native export, our converter produces clean, readable HTML
  • Preserved formatting - Cell structure, merged cells, and data types remain intact
  • Easy styling - Apply CSS to customize appearance for your website
  • SEO benefits - Search engines can read and index HTML table content

In our testing, the HTML output from our converter is significantly cleaner than Excel's built-in "Save as Web Page" function, which generates bloated code with inline styles.

Common Use Cases

Product Catalogs and Pricing

E-commerce sites need product tables with prices, specifications, and availability. Convert your Excel catalog directly to HTML and embed it on any product page.

Data Reports and Statistics

Research findings, survey results, and analytics reports often start in Excel. Convert to HTML to share them on company websites, blogs, or internal portals.

Schedules and Timetables

Event schedules, class timetables, and shift rosters are easier to maintain in Excel. Convert to HTML when you need to publish them online.

Technical Specifications

Product spec sheets, comparison charts, and feature lists convert cleanly to HTML tables for documentation sites and product pages.

XLSX vs HTML: Format Comparison

Understanding the differences helps you get the best results:

  • XLSX - Microsoft's spreadsheet format with formulas, charts, and complex calculations. Requires Excel or compatible software to open.
  • HTML - Web markup language displaying structured content. Opens in any browser, no special software needed.

When you convert, the visual table structure transfers to HTML. Formulas become their calculated values-you see the results, not the formulas. Charts and images are handled separately.

What Gets Converted

Our converter handles the essential elements:

  • Cell data - Text, numbers, dates transfer accurately
  • Table structure - Rows, columns, and merged cells preserved
  • Multiple sheets - Each worksheet can be converted
  • Basic formatting - Cell alignment and structure maintained

Note: Excel-specific features like formulas, macros, conditional formatting, and embedded charts don't translate to HTML. You get the visible data in table format.

Alternative Formats

HTML isn't always the best choice. Consider these alternatives:

  • XLSX to CSV - When you need raw data for databases or other applications
  • XLSX to PDF - For sharing spreadsheets that shouldn't be edited
  • XLSX to XML - For data interchange between systems

For web display with styling flexibility, HTML remains the most versatile option.

Tips for Best Results

In our testing, these practices produce the cleanest HTML output:

  • Simplify before converting - Remove unnecessary columns and rows
  • Use clear headers - First row should contain column labels
  • Avoid complex merging - Simple cell structures convert most reliably
  • Check data types - Ensure numbers and dates are formatted correctly in Excel

Works Everywhere

Convert XLSX to HTML directly in your browser:

  • Windows, Mac, Linux, Chromebook
  • Chrome, Firefox, Safari, Edge
  • iPhone, iPad, Android devices

No software installation, no account required. Your spreadsheet data stays private-conversion happens in your browser.

Pro Tip

Before converting, create a dedicated 'export' sheet in Excel with only the data you need for the web. Remove helper columns, hide calculation cells, and ensure headers are clear. This produces much cleaner HTML than converting your working spreadsheet.

Common Mistake

Converting entire workbooks with hidden columns, calculation sheets, and internal notes. Clean up your spreadsheet first-only include what should appear on the website.

Best For

Publishing data tables on websites where you need styling flexibility and SEO benefits. Product specs, pricing tables, schedules, and research data display beautifully as HTML tables.

Not Recommended

Don't use for interactive spreadsheets that need formulas or calculations. HTML is static display only. Also avoid for very large datasets-consider pagination or database solutions for thousands of rows.

Frequently Asked Questions

XLSX to HTML conversion transforms Excel spreadsheet data into HTML table code that can be displayed on websites. The table structure, cell content, and basic formatting are preserved in a format any web browser can render.

No. HTML is a display format, not a calculation engine. Formulas convert to their calculated values-you see the results, not the formulas themselves. For interactive spreadsheets, consider embedding options instead.

Yes. Upload your XLSX file and each worksheet can be converted to HTML. You'll get separate table code for each sheet in your workbook.

Yes. Unlike Excel's built-in 'Save as Web Page' which creates bloated code with excessive inline styles, our converter produces clean, semantic HTML that's easy to style with CSS.

Yes. Merged cells in your Excel spreadsheet translate to HTML colspan and rowspan attributes, maintaining your table's visual structure in the browser.

Absolutely. The output is standard HTML table markup. Add CSS classes, apply stylesheets, or use any web framework to customize the appearance for your website.

Charts and embedded images don't convert to HTML table format. The conversion focuses on tabular data. Export charts separately as images if you need them for your website.

Yes. Conversion happens in your browser-your spreadsheet data isn't uploaded to external servers. Your files remain private throughout the process.

The converter handles standard business spreadsheets without issues. For very large files with thousands of rows, consider splitting the data into multiple conversions for better performance.

HTML tables load faster, work without plugins, are searchable by search engines, and can be styled to match your website. Embedded Excel files require viewers to have specific software or plugins.

Yes. The output is standard HTML code. Open it in any text editor or HTML editor to make changes, add classes, or modify content before adding it to your website.

The numerical values transfer accurately. Specific Excel formatting (currency symbols, decimal places, percentage signs) may need CSS styling applied in the HTML to match your original appearance.
