Convert _XLS to XLSHTML

Understanding the xls and xlshtml file formats

XLS is a proprietary spreadsheet file format developed by Microsoft for use with Microsoft Excel. It stores data in worksheets, supporting formulas, charts, and formatting. XLSHTML is not a standard file extension, but it typically refers to an HTML file generated from an Excel spreadsheet, preserving the table structure and formatting for web display.

Why convert xls to xlshtml?

Converting XLS to XLSHTML allows you to share spreadsheet data on the web, making it accessible in browsers while retaining much of the original formatting and structure.

How to convert xls to xlshtml

The most reliable way to convert an XLS file to XLSHTML is by using Microsoft Excel. Here’s how:

1. Open your XLS file in Microsoft Excel.
2. Go to File → Save As.
3. Choose the location where you want to save the file.
4. In the Save as type dropdown, select Web Page (*.htm; *.html).
5. Enter your desired file name, ideally with the .xlshtml extension if you want to distinguish it.
6. Click Save.

This will create an HTML file that preserves your spreadsheet’s layout and formatting. You can then rename the file extension to .xlshtml if needed.
