Fast, stable and secure

Live, calculating web pages like these are very expensive to develop by hand with all the programming, testing and debugging that takes a lot of time even for a specialist.

By developing your expense report, order form or shipping calculator in Excel, you save a lot of time already at the design stage. Your calculator works and can be tested even before we turn it into a web page for you.

The converter turns the spreadsheet formulas into blocks of standard program code that have been meticulously tested by thousands of users.

The web pages are responsive and adapt to the screen width. On the narrow screen of the tablet, there is only room for two blocks side-by-side.


Our selection of flavors

  • Our basic product converts Excel spreadsheets to HTML with embedded JavaScript that can be used with any web server. All calculations are performed in the browser, without any help from the web server.
  • SpreadsheetConverter can also generate HTML5 web apps for iPhone and Android smartphones. These make it easy to collect data with mobile devices, select or configure products or do spreadsheet calculations in a smartphone. Web apps can be delivered through an app store and you can charge for them.
  • Special server products generate program code for Node.js, web servers. Since this flavor keep the formulas on the server and perform all calculations there, your business formulas are hidden from the end user. Running the formulas on the server also makes it much easier to add back-end integration, for example for saving and restoring values to a database. Communication with the server is minimal and the web calculator updates itself quietly in the background while the user is busy entering data into the next cell. Your technical people refer to this technology AJAX.

We first released SpreadsheetConverter in 2002, and have added more and more value to the product in many releases since then. Our update policy gives you free updates within the same major version, e.g. if you have a version 10 license you get all version 10.x updates for free.

We have three support centers in Europe, America and Asia that provide almost around-the-clock support during workdays. Technically competent support engineers will answer your e-mails and solve your problem. Most of them are programmers or web developers with long experience.
