An XLSHTML file is an HTML version of a spreadsheet created with Microsoft Excel, a spreadsheet productivity application. It contains the HTML representation of the source .XLS spreadsheet file, and is typically published online to be viewed in a web browser.

More Information

To create a webpage version of your document in Excel 365, select File → Save As, then choose the "Single File Web Page (*.mht, *.mhtml)" option from the dropdown menu. You can also choose to save your document as an .HTM or .HTML file.
