Instant Testing lets you quickly test each new version directly after conversion. For mobile devices, just scan the barcode to open the web page.
Instant Testing offers several time-saving services to developers:
Using the Browsers and Conversion Path Option you can get a list of all the web browsers installed in your system.
Select one or more web browsers by clicking on their icons. After each conversion, the converted web page will open automatically in all the selected browsers.
The Instant Testing web server in the development workstation attempts to provide the converted web page to any computer or other device on the same network. Copy the link and send it to other devices via e-mail or messaging.
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.
The ThemePreview toolbar also contains a convenient link to obtain the QR code, e.g. if you want to see how different themes change the appearance of a calculator in a mobile device.
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. If the web page is already open in your mobile device, just press the Reload button. It is usually a circular arrow (it looks like a “rotate clockwise” symbol) and it is often located near the website address field.
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. In this case you may get time-out error messages in your web browser saying
You should also check the Errors tab of the task pane for error messages like these from the conversion:
If you are trying to access the web page in the development workstation from another device, you should double-check that you are indeed connected to the same network as the development workstation. Your device should typically be showing a wifi symbol for the local network – don’t try this with a phone that says it’s connected with 4G or any other “G” because it won’t be able to reach your local devices.
Problems connecting to Instant Testing may be caused by the Windows Firewall in the development PC, which is blocking attempts to connect to the built-in web server node-ssc.exe (previously node.exe). Read more in the Firewall issues section below.
Another common problem is overly anxious antivirus and Internet security programs that incorrectly identify portions of our product as malware. We frequently see false alarms related to the node-ssc.exe or node.exe programs, in particular from Bitdefender. If you get such messages, you may have to whitelist the program or disable the antivirus program completely while using SpreadsheetConverter.
Read more in the help page for Internet security software.
In case you need to adjust the Windows Firewall in the development workstation to enable access to the built-in web server, please follow the instructions below.
The built-in server automatically finds a free incoming port, so the port number may change. You must ensure that the firewall is open 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.
