If you develop for mobile devices, the new Instant Testing feature lets you quickly test each new version from any device on the same network just by scanning a barcode.
The Instant Testing feature offers two time-saving services to developers:
SpreadsheetConverter automatically generates a barcode, a so-called Quick Response code, that contains a link to the converted web page in the developer’s workstation.
Special QR code reader apps allow you to scan the barcode with a mobile device to have the web page open automatically in a web browser on a smartphone or tablet. You can also use the barcode to open the web page in another laptop, if it has a camera. Read more in the QR code tutorial.
If you don’t need the QR code, you can easily disable the QR code window by deselecting the Show on conversion checkbox.
If you later need the QR code for a particular web page in the developer’s environment, just go to the History List and click on the new QR icon to open the QR code window again.
If you change your mind and would want the QR code window to appear automatically after every conversion, you can select the Show on conversion checkbox in any QR code window to reactivate it.
If you are viewing a converted web page from another device, you only need to scan the barcode the first time you open the page. After that, you can simply refresh the browser window to reload the most recent version from the development environment.
When you have finished testing a spreadsheet, you can of course keep using it from the development environment if all users are on the same network as the developer, and the development system is permanently online.
If you want to make a calculator or web form available outside your own local network, you still have to upload the converted web page to a public web server.
During the installation of SpreadsheetConverter, we install a tiny web server in the development environment that serves the converted web pages to web browsers in the same PC, or to other devices on the same network.
You may be unable to connect to the development environment from your cell phone, tablet or another laptop, and instead get time-out error messages saying
These problems are usually caused by the Windows Firewall in the development PC, which is blocking attempts to connect to the built-in web server node.exe. In this case you may need to adjust the Windows Firewall in the development workstation.
The built-in server automatically finds a free incoming port, so the port number may change. You must open the firewall for all ports that are opened by node.exe, not only the port number it is currently using.
The instruction on how to change these settings in the Windows Firewall are below. Please follow the instructions relevant to the version of Windows that is used in the development environment.
These instructions apply to the development workstation, e.g. the PC where you have installed SpreadsheetConverter, if it’s running Windows 8 or Windows 10.
These instructions apply to the development workstation, e.g. the PC where you have installed SpreadsheetConverter, if it’s running Windows 7.
These instructions apply to the development workstation, e.g. the PC where you have installed SpreadsheetConverter, if it’s running Windows Vista.
