Web calculators boost sales

Web calculators engage your visitors and make them interact with the website. If they save time or money using your calculator for a better purchase, or see how much they can save by refinancing a mortgage, they will return to your calculator over and over again.

A web calculator is also valuable on websites without products. If you can use your fantasy to develop a useful calculator, visitors will return to your site, and spread the word about your site.

The list of calculators you can offer is virtually endless:

  • Pick the best components for a loudspeaker system.
  • Calculate the right amount of seeds for their garden.
  • Find out if the odds for football matches provide any good betting opportunities.
  • Convert a recipe for a given amount of guests.
  • Calculate health characteristics like body mass index, calorie intake or energy consumption.

Online spreadsheets make your web professional

A time-saving calculator makes your web site stand out from the competition. 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.

We’re not only talking simple plus-and-minus spreadsheets here.

  • Create mobile-friendly, responsive forms that automatically adapt to different screen widths, portrait/landscape orientation etc.
  • To make it easier to understand a large form, split it into two or more separate steps and let users navigate between the sections using tabs, next/previous buttons or sliding panels.
  • Use graphical widgets like menus and calendars to make the form easier to use.
  • Hide rows or complete sections of a form until you know they are applicable.
  • Allow file attachments with submitted web forms.
  • You can have mandatory responses.
  • Use hidden fields to discretely include supplemental information in the form.
  • With Real-time Sync, two or more persons can share a web form and collaborate in real-time.
  • Fetch live data from corporate databases when run on ASP.Net or Node.js servers.
  • Build forms-based web apps for iPhone and Android devices that can submit smart forms directly  – even when the phone is offline.
  • Use live, interactive charts that invite users to point-and-click, and the charts automatically update when values are changed.

The free form-to-Inbox service requires no installation, no programming skills and no configuration. Once you upload your first web form to your server, submitted forms start arriving at your Inbox. You are up and running within minutes. For a small monthly fee, we can store submitted forms in a cloud database for you until you visit our server to pick them up.

 

Home Equity calculator with live interactive chart

This is one of our favorite examples because it shows the advantage of live charts. Change any cell in the spreadsheet and the chart immediately reflects the new values.

In this example, you can also see a useful implementation of a slider. To change the years remaining on a loan, we could just have used a standard numeric field. Using a slider allows for much easier visualization of how the equity varies over the lifetime of the loan.

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 deployment.
  • 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: your users can collaborate with colleagues in real-time directly inside the web page.
  • The Link Image widget allows you to show different images on 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.

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.

 

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.
 

Superior support

If you need help, don’t hesitate to contact our Help Desk. We guarantee free of-course-we’ll-get-you-up-and-running support during your free trial and for at least six months after you purchase a license. Expect an answer by the next business day, often within the hour.

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.

With any error report, we beg you to include the spreadsheet that’s causing you problems. Yes, we know they often contain terribly important information, but we need to recreate your problem in order to solve it, and it may be so difficult unless we have exactly the same data as you have.

If you buy a license, and we happen to release a new version within six months after your purchase, we’re not greedy – we’ll automatically give you a complimentary upgrade to the new version free-of-charge.
