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

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.
