Pro Tips

  • The Live Preview shows exactly how the table will render before you copy or download the markup
  • Choose the Styled option for a ready-to-use table with borders and alternating row colors, or Plain for a bare table to style yourself
  • The first row of the sheet is converted into <th> header cells; all other rows become <td> cells
  • Empty cells are preserved as empty <td> elements so the table's column count always matches the source sheet
  • The whole file is read and converted locally in your browser - nothing is uploaded anywhere

When to Use This Tool

Web Publishing

Turn a spreadsheet into an HTML table you can paste directly into a web page or CMS without needing a spreadsheet plugin.

Email Reports

Convert exported data into an HTML table that renders correctly inside HTML emails, unlike attaching a raw Excel file.

CMS Embedding

Generate table markup for blog posts, documentation, or knowledge base articles built in a CMS that accepts raw HTML.

Static Site Data Display

Produce a static HTML table for a site generator or internal tool without wiring up a spreadsheet-parsing library at runtime.

How It Works

1

Read the uploaded .xlsx file as binary data directly in your browser

2

Parse the file into a workbook using the SheetJS library, extracting all sheet names

3

Convert the selected sheet into a grid of rows and columns, treating the first row as headers

4

Build an HTML <table> element, escaping special characters in each cell

5

Optionally include a small CSS block for borders and alternating row colors

Frequently Asked Questions

Can I convert a workbook with multiple sheets?

Yes. After uploading, use the Sheet selector to choose which sheet to convert. Each sheet is converted independently into its own table.

What's the difference between Styled and Plain output?

Styled output includes a small embedded <style> block with borders, header shading, and alternating row colors. Plain output is a bare <table> with no CSS, useful if you plan to style it yourself.

Does formatting from Excel carry over?

No. Cell colors, fonts, and borders from the original spreadsheet are not preserved - only the cell values and the first row's role as headers.

Is my spreadsheet uploaded to a server?

No. The entire file is read and converted locally in your browser using the SheetJS library. Your data never leaves your device.

Why does the preview look different from my Excel file?

The preview uses generic table styling, not the fonts, colors, or column widths from your original spreadsheet, since HTML tables render based on CSS rather than Excel's formatting.
