Collaborate with Real-time Sync, HTML flavor

Use Real-time sync to share a live calculator or smart web form with other users, when the calculator has been converted for the web with the HTML flavor.

SpreadsheetConverter Real-time Sync lets you collaborate on a spreadsheet on the web. Multiple users can update the same electronic form or live calculator at the same time to make the work more efficient. In this help page, we will show you how to create a session and invite other users from a web page created with the HTML flavor of SpreadsheetConverter. There is a similar page describing Real-time Sync in the iPhone/Android flavor.

To create a session, you define a secret key for your calculator web page, then send it to your colleagues in an invitation to join the collaboration session.

Enable Real-time Sync

In Excel, use the SpreadsheetConverter settings for the workbook to ensure that the SpreadsheetConverter Real-time Sync option is turned on.


Convert the spreadsheet

Open your spreadsheet in Excel. Select the HTML flavor in the SpreadsheetConverter ribbon. Convert the spreadsheet by pressing the Convert button.

Upload the spreadsheet to a web server

Before you start collaborating on a spreadsheet, you must upload it to a web server. SpreadsheetConverter provides built-in sharing of web forms and calculators via Dropbox. To learn more, read the tutorial on Dropbox sharing.

You can also upload the web page to any web server, see the tutorial on how to upload a converted calculator or form.

Open the web calculator in a web browser

To start a collaboration session, you must first open the converted web page on the web in your web browser.

Start Real-time Sync

Click the SpreadsheetConverter Real-time Sync button in the bottom toolbar of the converted web page.


Enter a Secret key, which should be unique for each session, for your collaboration team (see the screenshot below). Use seven characters or more, preferably using a combination of letters, digits and certain special characters. For more detail, read more about the Real-time Sync security concerns.

Enter your name or e-mail address to identify you during the session. This name will be shown to the others in the session when you change field contents.

Press Connect to create the SpreadsheetConverter Real-time Sync session.



Obtain a link to the session

Invite other users to the session

Share the copied link among your colleagues, e.g. by e-mail or chat.

When users enter the session, they provide the name or e-mail address they wish to use during the session.

For your convenience, the secret key is included in the link. If you wish to provide this separately, you should remove it from the link before you share it with others, by removing ?k= and all the text afterwards.

Verify that other users are connected

Use the Real-time Sync button in the bottom toolbar to see all participants in this Real-time Sync session.



Start making changes

As connected users make changes to the spreadsheet, a colored arrow appears with their name.

Save the results

Each collaboration session is automatically saved after each change. The next time you connect to the session using the same secret key, the calculator or form will contain the values from the last time you used it.
