An XLSHTML file is best understood as an Excel spreadsheet that has been saved in a web page format rather than in a normal native Excel workbook format like .xls or .xlsx. Instead of keeping the file strictly as a standard spreadsheet, Excel converts the visible sheet into HTML, which is the language used to build web pages. This means the file may still look like a spreadsheet when opened, with rows, columns, headings, borders, colors, and cell content, but underneath it is structured more like a web page than a full Excel workbook.

In practical terms, an XLSHTML file is closer to an exported or published version of a spreadsheet than to the original working file itself. A normal .xlsx file preserves workbook structure, formulas, sheet relationships, and other Excel-specific features in a format designed for editing and long-term use. An XLSHTML file, by contrast, is mainly meant to display spreadsheet content in a browser-like or web-friendly form. Excel tries to preserve the appearance of the sheet, but the file is no longer stored in the same way as a true workbook.
This is why an XLSHTML file can sometimes open in Excel and in some cases may also behave like an HTML document. It is essentially Excel content wrapped in web page code. The layout may still resemble a spreadsheet, but the purpose is more about viewing and sharing than about preserving every Excel feature. Someone might use this format when they want to publish spreadsheet data online, email it in a viewable format, or create a mostly static version of a worksheet for display.
The important limitation is that not all Excel functionality carries over well into this format. While basic values, tables, and much of the formatting may remain visible, advanced formulas, workbook behavior, multiple-sheet structure, macros, form controls, and other Excel-only features may be reduced, altered, or lost. That is why XLSHTML is generally not the ideal format for keeping a master editable spreadsheet. It is more suitable as a display version of the file than as the primary working copy.
A simple way to think about it is that .xlsx and .xls are real Excel workbook formats, while XLSHTML is a spreadsheet converted into a web page representation. It may still look similar on the screen, but it is no longer the same kind of file underneath. In plain English, an XLSHTML file is an older Excel-as-HTML format used to show spreadsheet content in a web-style form, making it useful for viewing and sharing, but less reliable for full spreadsheet editing and long-term workbook preservation.
