How to append new Google Slides to an existing deck

Generate new slides and automatically append them to an existing Google Slides deck

We often create reports for a specific date range and we want to review them alongside the data from previous dates. One easy way to keep these reports organized is to append the latest slides to a master slide deck. Here's how to set this up in Slideform.

  1. Open your project by clicking Configure on the project card.
  2. Navigate to the Output tab and scroll down to the Advanced Settings.

  3. Open the Google Slides deck where you want to append the new output. This is your Master Deck. The best practice is to generate the output once, then use the Slideform output deck as the Master Deck. This ensures that all subsequent output will be added to this deck.
  4. WARNING: Do not enter the Google Slides template as your master deck. Doing this will result in an exponentially-growing slide deck that will quickly crash your account.

  5. Make sure the Master Deck is shared with share@slideform.co as an Editor.
  6. Enter the full URL of the master deck into Slideform.
  7. By default, new slides will be appended to the end of the Master Deck. To insert new slides at the beginning of the Master Deck, uncheck "Append to end."
  8. Scroll down to the bottom of the page to Save.

Note: Each time you run the project, the new output will create a new Google Slides presentation and those slides will actually be inserted as linked slides into the master deck. Do not delete the standalone Google Slides output or else the linked slides will also disappear from the master deck.
