How to convert XLSX to HTML?

You can convert XLSX to HTML with MConverter in three easy steps:

Choose XLSX files from your device or cloud storage
At the top of this page, drag and drop your XLSXs.

Alternatively, click on the Browse box to select files with your device's file picker, or copy and paste an XLSX file by pressing Ctrl+V (or ⌘+V on Mac).

MConverter can easily import XLSXs from Google Drive, OneDrive, and Dropbox.

Converting a folder with XLSX files to HTML is also supported: simply paste, drag and drop it, or use the ADD FOLDER button.
Click or tap on HTML from the list of target formats
You could also use the search box at the top right to quickly find the format you need, whether it's HTML or something else.
Get your HTML files after MConverter has finished processing them
Click on DOWNLOAD ALL to save your HTMLs to your default downloads folder, or select SAVE TO to choose another location.

You can also configure automatic file downloads during the conversion process or in the settings menu. When enabled, each HTML file is downloaded as soon as its conversion is complete, without waiting for the others to finish.

If supported by your device, you'll see a Share icon, allowing you to directly send converted files to other apps.

HTML, short for HyperText Markup Language, is the foundation for all web pages and websites. HTML files contain the basic structure of a web page, but they can also contain references to other resources, such as CSS for styling and JavaScript for interactivity. HTML files can be viewed with browsers, which interpret the code and display it to the user.
