Let a business expert create a calculator or web form as an Excel spreadsheet including all necessary formulas. Then let SpreadsheetConverter generate the ASPX- or classic ASP-page. When a field on the page is changed, all other fields are automatically recalculated, just like in Excel.

Either use the page as it is or open it in Visual Studio for further processing. You can add back-end integration, for example for saving and restoring values to a database.

While the user moves on to edit the next field in the form, the server dynamically instructs the browser to update any fields or charts that were affected by the previous data entry. This enables the browser to provide automatic background recalculation, while still fully exploiting the remote ASP.NET server.

It’s so easy to put any existing form or calculator on the web: expense reports, surveys, quote generators, order forms, reservation forms, employment applications, financial calculators, engineering tools – the list is endless.

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.
  • The formulas are protected: All calculations are done inside the Flash file, so your formulas are invisible to the user.
  • Everything is live and interacting with your visitors: The calculator or form updates dynamically when values are changed. Even the charts are live! 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. Play with new layouts inside Excel before you convert them to web format, which saves lots of time (besides being lots of fun).
  • 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.
  • 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 Flash animation 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.

 

A happy web user likes a calculator that gets data off a secure Windows server with ASP.NET
 
With the ASP.NET version of SpreadsheetConverter, a portion of the web page resides on a Windows server behind the corporate firewall. This makes it much easier to fetch data from a secure database, e.g. the current interest rate, or interact with other server applications. All the sensitive formulas and business rules in the spreadsheet are also inaccessible behind the firewall.

All calculations are performed securely on the server by separate ASP.NET or classic ASP modules, freeing the browser from the workload required to do all the computations. This enables the browser to handle complex user interface logic even for very large web pages.

To maintain rapid response times, SpreadsheetConverter uses state-of-the-art Ajax technology to recalculate only the cells affected by each change. The spreadsheet is then silently updated while the user moves on to another cell.

Fast calculation with prefabricated components

Creating a calculating web page like an expense report or order form online can be very difficult. Programming, testing and debugging takes a lot of time even for a specialist. Most online calculators do all their calculation on the web server, which can make the web page slow because of all the network communication with the server.

With SpreadsheetConverter, all your spreadsheet formulas are automatically converted into program code by SpreadsheetConverter, using prefabricated components that have been meticulously tested. The conversion to web format retains the interactivity that is typical of a spreadsheet, and the entire visual layout is carried over to the web page.

All calculations can be done in the browser, without any help from the web server. Our basic product converts Excel spreadsheets to HTML with embedded JavaScript that can be used with any web server. The Flash version creates standalone Adobe/Macromedia Flash files that you can use on any page in your blog or website.

SpreadsheetConverter can also generate HTML5 web applications for iPhone and Android smartphones. This makes it easy to collect data with mobile devices, select or configure products or do spreadsheet calculations in a smartphone.

For developers, there are special server products that also can generate program code for ASP.NET and classic ASP web servers. This 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 another cell.

The new version 6 provides a new user interface that lets you work faster and more reliably. Power users move ahead up to four times faster, while new users get much more help and overview. You can use two or more flavors of the product simultaneously, and publish your results directly on the Internet on a free web server.

  • This is an excellent tool. I did most of what I wanted to do without reading the guide.

Low cost, no risk

The Standard edition of SpreadsheetConverter to Flash costs $187. The Professional Edition lets you create web pages for clients, supports more functions and more chart types, and costs $357.

Excel and SpreadsheetConverter are only used when you create the spreadsheet and convert it to web format. We charge a small one-time license fee for each computer on which you install the program to perform such conversions.

  • There are no additional fees per page or conversion.
  • There are no additional fees per web server, page view or visitor.
  • There are no additional fees for Excel or plug-ins. The web pages we create have everything in them and do not need or use Excel.

In fact, when spreadsheets are available online like this, many people no longer need their own Excel licenses, which can generate additional savings.
