Build an interactive web calculator in JavaScript from an Excel spreadsheet. Save hours of programming by using tested and trusted code libraries.
Your customer wants a simple JavaScript calculator for their website. In theory it is easy to program, however handling all possible errors, formatting the data and implementing the calculation can be rather tedious. A better solution is to create the entire calculator with Excel, and convert the Excel formulas to JavaScript using SpreadsheetConverter.
You create the calculator in Excel in no time. The machine conversion to JavaScript will be well tested, since thousands of users test our calculation engine daily. You get a fast, online JavaScript “spreadsheet” with all the features that your customers expected.
See examples of what SpreadsheetConverter can do for you.
Free offer: Send us a spreadsheet and we’ll send it back as a web page.
JavaScript spreadsheets activate your visitors and make them interact with the website. If they save time using a price calculator for a quote, or see how much they can save by refinancing a mortgage, they will return to your calculator over and over again.
A Excel JavaScript 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 it.
Excel and JavaScript are natural matches. Your web forms can have embedded calculations and validations. The entered data is collected and made available to you. Typical examples are:

SpreadsheetConverter is the perfect tool for creating calculating web forms and web pages that attract attention.
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.
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.
The calculations and data behind our Covid-19 risk assessment model are quite complex and without the Spreadsheet Converter we would have not been able to post the tool online in a reasonable time frame.
We are thrilled to have found this solution and would highly recommend it to others considering upgrading their spreadsheets to online tools!
I have found your product to be simply marvelous, and the support excellent. Many thanks.
I was able to release an android app on Google Play. Not bad for a guy who did not know what an app was 6 months ago.
By the way---thanks again---this software is awesome!
Many many thanks!!! In case you need a reference, do not hesitate to let us know. We have a sheet which is integrated in WordPress.
Your app is great!
We use SpreadsheetConverter to create design tools for our products. The Professional edition is able to handle a very large and complex Excel workbook, and saves our web programmer a significant amount of time.
That's brilliant! I can do a lot with that. As always, awesome stuff!
I wish your company well. You have a great product for many purposes.
I am an app developer. I found the spreadsheet converter software and it has made app development so much better and easier.
Love your products. Just amazing! Can I switch to the mobile converter?
I started two months ago developing a reservation system for my wine tour business in Excel and converted it for the website with Spreadsheet Converter.
Absolutely great product that saved hundreds of hours of manual coding converting my excel calculators to web pages.
I remain impressed. You have a phenomenal product.
Please forward my congratulations to your development team, as they have done an outstanding job!

Version 7 is brilliant, the way it shows and prints on a Mac, iPad and iPhone - WOW!
The converter is amazing.
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.
SSC7 is AWESOME! I am very happy about the show/hide rows or sheets - that's an incredible development for me.
This program was a great find for us. Eliminated plenty of money developing custom website as I do this all myself. Plus it has such great features and flexibility, customers love the interface.

Everything worked so well that we bought the software.

We guarantee the best support. During the trial period we will do our best to help you succeed, and six months of e-mail support is included in the price for all products. We promise answers by the next business day, but within the hour is our goal.
SpreadsheetConverter is a mature product that has been for sale since 2002. We constantly add new features to the product. Updates are free within the same major version, so if you buy any version 10 product, all 10.x updates are free.
We are pretty well staffed when it comes to support. Some of our best programmers like to be on call now and then. Most weekdays support will follow the sun from our Asian help desk via Europe to our support center for the Americas in West Virginia, USA. Usually you get to talk directly to the developers, or one of our web designers.
Some errors are really hard to recreate, and then it becomes very difficult for us to see what’s causing your problem. In many cases we may have to ask for a copy of your spreadsheet.
If we release a new major version within six months from your purchase, the upgrade to the new version will not cost you anything. That’s the kind of really nice guys we are.
I have found your product to be simply marvelous, and the support excellent. Many thanks.

SpreadsheetConverter is an add-in for Microsoft Excel in Windows. It appears as an extra menu in Excel. 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 Excel add-in to perform such conversions.
In fact, when spreadsheets are available online like this, many people no longer need their own Excel licenses, which can generate additional savings.
There is no risk, you’re safely protected by our 30-day money-back guarantee. If you are not satisfied with your purchase, just send us an e-mail, and we will cancel your purchase and refund the money.
