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.
To display the QR code for a particular web page in the developer’s environment, just go to the History List and click on the QR icon to open the QR code window.
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 probably won’t be able to reach your local devices.
Some overly anxious antivirus and Internet security programs may 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.

The only traffic going into your network should be things that you or someone else asked for, like web pages, downloaded files or e-mail. Your network has one or more “firewalls” that prevent unauthorized network connections to your devices. If someone on the outside attempts to connect to a suspicious program in your laptop, it’s probably a bad thing. One of the firewalls should detect and prevent this intrusion.
Most networks have a primary firewall in or near the network’s outermost router or gateway, the one that connects your network to the public Internet. Many network devices like computers and smartphones also have their own firewalls. The firewalls monitor the applications to see what network ports they open, and allow data to flow through authorized connections. Unauthorized connections are terminated.
When we install our small web server in the development workstation, we do attempt to register it properly in the Windows Firewall. In case it doesn’t work as expected, you must adjust the firewall to enable access to the built-in web server, or our preview functionality will be unavailable. 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-ssc.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. If you use a third-party firewall, please follow the corresponding instructions in the applicable documentation.
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.
