SpreadsheetConverter in many flavors

Our basic product is called SpreadsheetConverter HTML. It generates standard cross-platform web pages in HTML with the Excel functionality provided by Javascript programs and HTML5 charts embedded in the web page. The resulting web pages can be hosted on any web server and runs in all modern web browsers in laptops, tablets and mobile devices. Responsive design allows your spreadsheet to dynamically reformat itself to perfectly fit any screen size.

Anyone can develop mobile calculator apps for smartphones with the iPhone/Android version. Collect data on the road, or keep your favorite spreadsheet in your jeans pocket.

For advanced users, we provide Professional editions of the program, that cater for the extra needs of professional web authors and developers – and quite a few power users as well.

Special server products can generate program code also for Node.js servers, typically to hide the spreadsheet formulas, or on ASP.NET and classic ASP web servers.

To buy a new license or add additional flavors to an existing license, visit the license shop.

Forms-to-inbox services

If your spreadsheet is used as an online form that visitors can enter data into, you can add a Submit button to the form that sends each completed form to your inbox using our Free or Advanced Submit Service.
