Convert XLSHTML to XLSMHTML

Understanding xlshtml and xlsmhtml file formats

XLSHTML is not a standard file format but typically refers to an HTML file generated from a Microsoft Excel spreadsheet, often by saving or exporting a worksheet as a web page. These files contain HTML code that represents the spreadsheet's data and formatting, making it viewable in web browsers.

XLSMHTML (also known as MHTML or .mht) is a web archive format that encapsulates HTML and all linked resources (such as images, stylesheets, and scripts) into a single file. When Excel saves a worksheet as a Single File Web Page, it uses the .mht or .mhtml extension, allowing the entire spreadsheet to be shared as one file with all its resources embedded.

How to convert xlshtml to xlsmhtml

Since xlshtml is essentially an HTML file exported from Excel, and xlsmhtml is a web archive format, the conversion process involves re-saving the HTML file as a single file web page. This can be done using Microsoft Excel or a web browser that supports MHTML export.

Best software for xlshtml to xlsmhtml conversion

• Microsoft Excel: The most reliable way to convert is to open the original Excel file (if available) and use Excel's export feature. If you only have the HTML file, you can open it in Excel and then save it as a single file web page.
• Microsoft Word: Word can open HTML files and save them as MHTML. Open the HTML file in Word, then use File → Save As and select Single File Web Page (*.mht; *.mhtml).
• Web browsers (like Internet Explorer): Open the HTML file in Internet Explorer, then use File → Save As and choose Web Archive, single file (*.mht).

Step-by-step conversion using Microsoft Excel

1. Open the original Excel file or the HTML file in Microsoft Excel.
2. Go to File → Save As.
3. Choose the location and set the file type to Single File Web Page (*.mht; *.mhtml).
4. Click Save to create your xlsmhtml file.

Tips and considerations

• If you only have the HTML file, some formatting or features may not be preserved when opening in Excel or Word.
• MHTML files are best viewed in Internet Explorer or Microsoft Edge (IE mode), as not all browsers support this format natively.
• For batch conversions or automation, consider using command-line tools or scripts, but manual conversion via Excel or Word ensures the best fidelity.
