Please do not test smartphone calculators with your desktop browser. The smartphone calculators have been optimized for the smartphone’s small and narrow screen and do not fit a wide screen.

Here are a few tips on how to test web pages in iPhone, iPad or Android.

Free offer: Send us a spreadsheet and we’ll send it back as a web page.

Features and benefits

SpreadsheetConverter is the perfect tool for creating calculating web forms and web pages that attract attention.

  • Instantaneous response: All calculations and validations are done immediately when the user enters new data. Everything is done in the browser. No communication with the web server.
  • Everything is live and interacting with your visitors: The calculator or form updates dynamically when values are changed. Even the charts are live and allow users to focus on the data they are most interested in. Use calendars to select dates, stars to set ratings and sliders to vary data in real-time. Create forms with dropdown menus, checkboxes, radio buttons, large text fields, list boxes in a breeze. Design step-by-step wizards for complex forms.
  • It looks so good on the web: Normally, it takes a lot of time to make a web page look this well-designed. With Excel you just format the page the way you like. SpreadsheetConverter creates a web page that looks the same: borders, colors, fonts, checkboxes, dropdown lists etc work as they should, and numbers are formatted on the fly with decimals, thousand separators and currency symbols. Conditional formatting makes the most important numbers stand out. Design colorful themes the give your online spreadsheets a common look.
  • Built-in web publishing. The Publish to Cloud feature instantly publishes your converted web pages on distributed Amazon S3 web servers for rapid global performance.
  • You get a free WordPress plugin that imports converted Excel spreadsheets into WordPress. Create live calculators and smart web form and display them in your pages or posts.
  • All devices supported: the calculator or web form automatically adapts to the small screen in a smartphone or tablet, to look and work well on any device.
  • Integrates with existing systems in many ways, e.g. sends data with barcodes, http or e-mail; receives data via http.
  • Two or more team members can share the same spreadsheet: collaborate with your colleagues in real-time to create and analyze calculating forms and web pages.
  • The Link Image widget allows you to show different images in the web page depending on cell values or formulas. Now you can build advanced imaging applications where an image on the screen changes with the values in a web form or calculator.

  • Automatic form-to-Inbox delivery: When users submit completed forms, SpreadsheetConverter delivers them directly to your e-mail Inbox. For a small fee, forms can be saved in a database for later retrieval, thanks to a hosted service that requires no local installation or server.
  • Users can include up to ten files with any form they submit. Job applicants can include their CV, and expense reports can include scanned copies of receipts.
  • It’s so easy to change: Business rules frequently change, e.g. new prices, new discount options, new regulations etc. With hand-crafted web pages it’s hard to keep up with the frequent changes. With SpreadsheetConverter, you just change the spreadsheet, and regenerate the web page.
  • Scalable: Once the web page is downloaded into the visitor’s web browser, no resources are needed on the web server. So if your current website can handle 1,000 simultaneous visitors, a calculator you create with SpreadsheetConverter can be used by 1,000 simultaneous visitors.
  • You get the source code: The web page is completely self-contained. There are no library files or other external requirements.
  • There are no errors: The calculator doesn’t need any testing, since thousands of users already have tested our calculation engine.
  • It’s cost-effective: You need the SpreadsheetConverter program only when you perform the actual conversion from spreadsheet to web page format. You need one license for each PC on which you install the program to perform such conversions.
  • Excel isn’t needed: Once the web page is created, Excel is not required. Your web server doesn’t need Excel, and your users don’t need Excel. Even if Excel is all around, not all employees have it, and private persons seldom have it.
  • It’s free to distribute: With the Professional Edition, you can make the calculator part of a product that you sell.
  • You take no risk: Every purchase comes with a 30-day money-back guarantee and six months of free e-mail support.

Build powerful apps from Excel prototypes

Developing smartphone apps for Android and iPhone has never been this easy. Just create the table, calculator or form you want with Excel. SpreadsheetConverter iPhone/Android converts the spreadsheet into a calculating app in the form of HTML 5 web pages for iPhone and Android smartphones.

Apart from the small screen on the smartphone, everything works just like in Excel. Use the formulas and functions you know and love, and format the layout just about any way you like.


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, ASP.NET and classic ASP web servers. Since these flavors 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.
