If your calculator is for a blog, it may be easier to just upload it and show it in an iframe. To support an increasing number of mobile visitors, we recommend that you use the iPhone/Android flavor instead.

Let a business expert create a calculator or web form as an Excel spreadsheet including all necessary formulas. Then let SpreadsheetConverter convert the spreadsheet to a live Flash animation. When a field on the page is changed, all other fields are automatically recalculated, just like in Excel.

With SpreadsheetConverter, anyone can create a calculating order form that can be automatically sent to your order desk just like with a web shop. Our form delivery service sends each completed form as an e-mail, or stores them in a database for easy download.

Note: SpreadsheetConverter Flash is being phased out, and the information on this page may not be current anymore. Version 7 can still be downloaded from our download page. If you want to build advanced web components from Excel spreadsheets, consider converting to HTML/JavaScript, iPhone/Android, Node.js or ASP.NET instead.

It's so easy, you can do it yourself!

In the old days, we used to pass good spreadsheets around. But there were always the old versions floating around that you couldn’t get rid of, with old prices or discounts. As people started making changes to keep up with new business rules, there suddenly were many different versions of the same spreadsheet.

SpreadsheetConverter lets you easily share any Excel spreadsheet with friends, co-workers or customers. It does this by converting your spreadsheet to a live, interactive web page with tabs and charts. If someone edits a value, everything recalculates automatically. You can do this with absolutely no programming!


This way you can share your spreadsheet without releasing control of it. If business rules change, you just update your source spreadsheet and convert it again. You can even hide the formulas with one of our web server flavors.

You can also design smart web forms in Excel, validating user input with Excel’s Data Validation features or with formulas.

You can split forms into sections that the user proceeds through using a Next button or by clicking on panels. You can hide sections until they are needed in a survey or application form.

With forms you get a Submit button that sends the completed form to any e-mail inbox. We can also save survey responses etc in a cloud database – just download any new responses whenever you like.

Just put your Excel skills to work and publish your favorite calculators and smart web forms on the web.

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.

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.

Just slip the calculator into any blog or web

With the arrival of SpreadsheetConverter to Flash, anyone with basic Excel skills can create invaluable calculators, smart forms or live charts from a plain spreadsheet, and then convert it into a complete, self-contained Flash file.

Using the Flash file is just as simple as adding an image or a movie to your blog or website. Simple step-by-step instructions help you insert Excel spreadsheets, calculators or charts into environments like WordPress, Blogger, Drupal or Joomla in just a few minutes, thanks to the convenient Flash format.

The Flash file contains all the programming logic and formatting information from the spreadsheet. Your formulas and business rules, previously visible in the spreadsheet, are now cleverly concealed in the Flash file.

Flash is one of the best established platforms on the web, and more than one billion Flash-enabled mobile devices have been shipped to consumers. Spreadsheet Converter is a clever shortcut to advanced Flash programming that lets you grow with that momentum.


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.
