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! 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). For a stringent corporate look, apply the same visual theme to all your calculators.
  • Use if from any type of device: responsive blocks automatically fit any screen, both your handheld devices and your desktop screen.
  • True, real-time, online collaboration: multiple users can update the same calculating web page or web form at the same time, seeing each other’s changes.
  • 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.
  • No debugging: No HTML or JavaScript knowledge is needed. SpreadsheetConverter generates bug-free HTML and JavaScript directly from the Microsoft Excel spreadsheet.
  • 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.
  • 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.

SpreadsheetConverter is a unique product

Only SpreadsheetConverter HTML works on all web servers, since we do the calculations using JavaScript. JavaScript is always supported.

Only SpreadsheetConverter has royalty-free distribution. No extra per-server fees.

SpreadsheetConverter makes business users more productive

  • 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.
  • Use your existing skills. If you can do it in Excel, you can put it on the web.
  • It supports almost all Excel’s built-in functions. Currently all but a few advanced financial and statistical functions are supported.

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.

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 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.

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, the 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 another cell.

  • I have been a long-time user of ExcelEverywhere and SpreadsheetConverter and have frequently had issues, made suggestions etc. All have been resolved satisfactorily. However, I have to say version 8 is absolutely brilliant and unlike in the past there is no "but ..."! With a bit of imagination there is virtually nothing that can't be delivered using it. Well done to all and thanks.
