About Excel to HTML
This Excel to HTML converter uses SheetJS to transform xlsx and xls spreadsheets into styled HTML tables locally in your browser. The conversion preserves cell data types, merged cells (colspan/rowspan), alignment, and basic formatting, generating semantic table, thead, and tbody structures. The output includes responsive styling and can be embedded in web pages, email templates, or documentation systems. It is worth understanding the boundary of what conversion handles: embedded images, charts, conditional formatting, and elaborate fonts do not survive; what does survive is the cell values, merged layout, and coarse alignment, which makes this ideal for turning a structured data sheet into a long, web-friendly table. If the source contains formulas, confirm the computed results are what you expect before converting, because SheetJS reads the calculated result rather than the formula itself. Custom CSS class names help the table melt into an existing site's design system without re-styling by hand.

FAQ
Are merged cells preserved after conversion?
Yes. The tool converts Excel merged cells to HTML colspan and rowspan attributes, maintaining consistent table layout.
Can the output HTML be used directly?
Yes. The generated HTML includes semantic table, thead, tbody structures and basic styling, ready to paste into web pages or email editors.
Does it support custom styling?
Yes. You can customize CSS class names to replace defaults and modify alignment, borders, and background color properties.
Can it handle cells with formulas?
Yes. SheetJS reads formula result values rather than formulas; the HTML table displays computed values, so verify them before publishing.
Are embedded images or charts converted?
No. Rich objects such as images, embedded charts, and conditional formatting do not become table content; only data values, merged layout, and basic alignment carry over.
Are the files uploaded?
No. All parsing and conversion run locally via SheetJS; your file never leaves the device, so sensitive reports can be handled safely.
