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.

The interactive charts can be manipulated directly by your website visitors. This increases the value of any chart, and involves your visitors in the analytical process.

  • Click on a data series to show or hide the series.

A calculating web form for catering orders

This one started as a spreadsheet we created to calculate catering costs. After a while, we found that people were using old versions with old prices. With SpreadsheetConverter, we could convert our spreadsheet to a web page calculator that people could use directly on our internal web.

When prices change, all we have to do is update and convert the spreadsheet, upload it on the web, and the new prices are immediately there for everybody.

Before we started using SpreadsheetConverter, we were always chasing people, asking them to provide additional information that we just must have to process a catering order, e.g. their cost center numbers. Then we found out how to add a Send button to our little calculator. Now, after people have specified their requirements and checked the prices, they can send us their order directly from our web page with just a click of a button.

SpreadsheetConverter allows us to make certain fields in the catering order form mandatory. So now, no-one can send us a catering order without specifying their cost center. You bet it saves us time!

Build powerful web apps with Excel

This developer is using Excel to create a calculator for a loan application form, and previewing the form on an iPhone.

You only need basic Excel skills to develop powerful web apps.

  • Use the iPhone/Android flavor to fully utilize touch screens.
  • Use the HTML flavor for a responsive design that adapts to the width of each screen.

Everything works just like in Excel. Use formulas and functions to calculate values, and design the layout with Excel’s formatting options. Everything you do in Excel comes across to the web app.


Create beautiful web apps for iPhone and Android

The screenshot is from a mobile web app that was directly converted from an Excel spreadsheet. The app calculates the monthly payments for a car loan depending on time and interest. It also shows you the total interest paid for the loan. For us, it also demonstrates some of our popular web widgets and the powerful hide rows feature.

To test the Car Loan calculator in your phone, scan the QR code below.

If you’re uncomfortable doing that, read our tutorial about scanning QR codes.

If you want to build apps like this just by converting Excel spreadsheets, read the guide to creating iPhone/Android web apps from Excel spreadsheets.


A responsive spreadsheet that adapts to the screen

Historically, most spreadsheets were made very wide to fit the desktop screens of long ago. Today, this landscape-oriented design makes old spreadsheets difficult to use on smaller devices that are mostly used with the screen in portrait orientation. The unnecessarily wide layout requires a lot of horizontal scrolling.

Other solutions may force you to create a separate “mobile” version of each spreadsheet. With SpreadsheetConverter you can instead easily divide the spreadsheet into responsive blocks that naturally flow across the screen to fit any screen width.

With responsive design, your web calculator or form automatically adapts to different screen widths.

  • A visitor with a wide screen sees the responsive blocks for JanuaryFebruary and March in the same horizontal row.
  • On a tablet, the calculator automatically shrinks to a two-column layout. The March block appears below the January and February blocks.
  • On a phone, there is only room for a single block at a time on the narrow screen. The February block comes after the January block, before the March block.

Responsive blocks are easy to use and with little effort make almost any old and wide spreadsheet fit even the smallest screens.
