No re-upload neededThese tools accept .HTML - your file is handed over directly.
No. Everything runs in your browser - your file never leaves your device. How this is verifiable
Sometimes a table just needs to be shown - in a newsletter, on an internal page, or as an attachment anyone can open without Excel. A standalone HTML file with a real <table> is more universal than a screenshot for this and stays searchable and copyable.
This tool reads the workbook entirely locally in the browser (SheetJS, pure JavaScript) and builds an HTML table per sheet, with borders and readable row spacing. A single sheet yields one lean HTML file; several sheets are combined into ONE file, each under its own heading carrying the sheet name.
Nothing is uploaded - unlike online converters that send Excel files to a server. The conversion even works offline after the first load.

Limitations: Formulas become their computed values; cell colours, charts and macros are lost. Several sheets land one after another in one file, not on separate pages. The HTML file carries only plain, embedded styling - no responsive or interactive layout. Very large workbooks need memory.

Yes, it is a standalone HTML document with embedded styling.
They land in ONE HTML file, each under its own heading.
