What is a .XLSMHTML file?
An .XLSMHTML file is a type of file created by older versions of Microsoft Excel, specifically the 2007 edition and earlier. This file format is essentially a Microsoft Excel MIME HTML Spreadsheet. The purpose of an XLSMHTML file is to archive a spreadsheet in a way that it can be viewed in a web browser. This is achieved by saving the spreadsheet data as HTML code, which is the standard code used to create web pages. The HTML code in an XLSMHTML file mimics the appearance and structure of the original spreadsheet that was created in Excel, typically with a .XLS extension.
However, it's important to note that newer versions of Microsoft Excel no longer support the creation or opening of XLSMHTML files directly. This means that if you have an XLSMHTML file, you cannot open it using the latest versions of Microsoft Excel. Instead, you can view these files using a web browser like Google Chrome, Mozilla Firefox, or Microsoft Edge. Simply open your web browser, go to the file menu to open a file, and select the .XLSMHTML file. The browser will display the spreadsheet as a web page, allowing you to view but not edit the content.
If you need to edit the contents of an XLSMHTML file, you might consider converting it back to a standard Excel format using third-party file conversion tools available online. This conversion would allow you to open and edit the spreadsheet in newer versions of Excel or other compatible spreadsheet applications.
