The .xlshtml file extension was used for Microsoft Excel documents saved as HTML by previous Excel versions. The latest version of Excel 2010 does save HTML documents, but uses the .html file extension instead. This xlshtml file format is obsolete and no longer supported. Many files contain text data. There are some programs that can open unknown files.
Associating the XLSHTML file extension to corresponding software in the Windows Registry is difficult. Is there a simple way to open these unknown file types? To open files, users can select, download, and install relevant software. For xlshtml files, old versions of Excel may work even though Microsoft no longer supports that format.
Excel’s default format is now .xlsx starting in Excel 2007. Other Excel formats like .xlsb take up less space and open faster! The focus in exporting Excel data is enabling third party software compatibility, not which internal format is used. So Excel offers different writers to take advantage of each format.
